Error 256 linux

Oops!! Frustrated with YUM error 256? We can help you fix it.

This error occurs due to many reasons including corrupted YUM cache, configuration changes, etc.

At Bobcares, we often get requests from our customers to fix YUM error 256 as part of our Server Management Services.

Today, let’s get into the details on how our Support Engineers fix this problem.

When does YUM error 256 occur?

YUM is an open-source package management tool for RedHat Package Manager based Linux systems. It makes package installation a simple process.

However, while using YUM, we may encounter many errors. Today, we discuss in detail on how to fix one such yum error having code 256.

This error occurs mainly due to:

• corrupted YUM cache
• inaccessibility of a repository URL from the system
• due to some configuration mistakes

Let’s see how our Engineers find the fix for this error.

How do we fix?

We just saw the common reasons that could result in Yum errors. And, the fix can vary depending on the triggering reason. Let’s see the top ones.

1. Corrupted Yum cache

Recently, one of our customers approached us with an error in his RHEL6 server. He was trying to install the java package.

We checked and confirmed that the folder /etc/yum.repos.d contained only valid repositories. The link was also working correctly when accessed via a browser. Thus the problem happened due to YUM cache corruption. So, we did the following:

Firstly, we removed the old YUM cache from the system by running the following commands:

rm -rf /var/cache/yum/*
yum clean all

Then updated the packages using

yum update

Thereafter, the java package installation went on fine.

2. Incorrect repository

Similarly, YUM error 256 can happen due to incorrect repository set up too.

In one of the cases, the customer was using a local repository on his server. Here the GPG check was failing.

Therefore, our Engineers fixed the problem by making the following changes in /etc/yum.repos.d/_local.repo.

gpgcheck=0

That removed the GPG check and the yum started working again.

[Having trouble with YUM commands on your server? We’ll fix it for you.]

Conclusion

In short, this error occurs due to many reasons including corrupted YUM cache, inaccessibility of a repository URL from the system, etc. Also, we saw how our Support Engineers fix this error.

WoeUSB это приложение для создания загрузочного носителя для операционных систем Windows из дистрибутива Linux

Если вы ищете, как установить и использовать WoeUSB, у нас уже есть статья а также видео, демонстрирующее весь процесс в деталях.

Когда «вилка упала»

Я использую WoeUSB в течение долгого времени, и ни разу мне не удавалось создать загрузочную флешку Windows с помощью программного обеспечения. Тем не менее, я постоянно вижу отчеты на нашем форуме, Диолинукс Плюсот людей, у которых был неприятный опыт с программой.

Именно в одном из этих отчетов я увидел, как пользователь объяснил, что он не может использовать программное обеспечение из-за печально известной «Ошибка 256», и именно в этот момент я понял, что уже получал такое же сообщение об ошибке раньше. Однако в моем случае мне всегда удавалось устранить это небольшое неудобство относительно простым способом.

В тот момент я решил воссоздать здесь, в моей системе, ситуацию, в которой возникает ошибка, чтобы задокументировать эффективный способ ее решения! И, наконец, вот руководство, предлагающее решение.

Сначала я расскажу, в какой ситуации возникает «Ошибка 256».

Во всех моих тестах эта ошибка возникала только тогда, когда я пытался использовать флешку, которая уже содержала записанный с нее образ какого-то дистрибутива Linux. Чтобы использовать USB-устройство с WoeUSB, оно должно быть отформатировано в fat32 и желательно пустым.

Это связано с тем, что способ разбиения и форматирования флеш-накопителя при получении загрузочного ISO из системы Linux несовместим с тем, как WoeUSB работает с файлами ISO Windows, и именно здесь «Me # д * »все происходит.

Чтобы использовать такое устройство с образом Windows, необходимо отформатировать его. Однако в этих случаях недостаточно просто щелкнуть «Формат», нам также необходимо создать новую таблицу разделов на устройстве.

Когда отображается «Ошибка 256», также отображается сообщение о том, что «целевое устройство в настоящее время занято, размонтируйте все разделы, установленные на целевом устройстве, и повторите попытку».

Оказывается, это сообщение может немного сбивать с толку, ведь при разборке целевого устройства (которым является флеш-накопитель) оно просто «исчезает» из системы, что делает невозможным его выбор в WoeUSB.

Для решения проблемы вы можете использовать приложение под названием «Gparted». После того, как вы установили его, откройте его и убедитесь, что ваше устройство флэш-памяти выбрано (вверху справа). Нажми на “устройство“А потом”Создать таблицу разделовВ появившемся диалоговом окне выберите «MSDOSИ затем нажмите «Применять».

После этого появится сообщение об ошибке, просто нажмите «игнорировать».

Теперь полностью отключите флэш-накопитель от USB-порта, подождите 5 секунд и замените его. Что сделано, в левом верхнем углу программы нажмите на меню «Gparted“А потом”Обновить устройства».

В верхнем левом углу Gparted нажмите «Создать новый раздел». В открывшемся окне, в поле «Файловая система“Выбрать”fat32“, в “метка«Введите все, что вы хотите (например,« Pen Drive »), а затем нажмите«Добавить».

Дождитесь завершения операции и в поле «Применение отложенных операций“щелкнуть”близко». Также закрой Gparted и иди!

Ваша флешка готова для получения изображения Windows через WoeUSB без проблем.

Вероятно, это одна из единственных причин, по которым у многих людей возникают проблемы с использованием WoeUSB. Исходя из моего опыта, это программа, которая всегда очень хорошо выполняла свою работу.

Я надеюсь, что, следуя этим советам, вы также сможете насладиться лучшим из WoeUSB. И избавьтесь от «головной боли» каждый раз, когда вам нужно создать загрузочный носитель Windows на Linux.

Были ли у вас проблемы при попытке использовать WoeUSB? Вы уже знали это решение? Расскажите в комментариях ниже о своем опыте работы с WoeUSB до и после этого совета. И если у вас есть еще лучший совет, обязательно поделитесь им с нами!

Вот и все, ребята! ?

с такой картинкой только ванга или кашпировский сможет понять что нибудь.
так,навскидку,что по форумам часто пишут про Arch Linux install script,вроде устанавливает только на разделы uefi ,на mbr не устанавливается.
лично сам не пробовал и не собираюсь,проще и лучше установить стандартным способом.
или в крайнем случае что-то вроде EndeavourOS с графическим установщиком как в убунту.

Re: Whichever game I try to install on Lutris returns me with the error code 256

Post by ThaCrip » Wed Jul 13, 2022 1:35 am

I can’t answer your question directly since I never tried to install games through Lutris directly.

but I do use Lutris (currently v0.5.10.1), with the newest stable Wine from the winehq website, and then I pair it with GloriousEggroll runner for Lutris for the small amount of games I replay (Mafia series and RDR2(with RDR2 I have to set Wine to Windows 10 mode as if you leave Wine in the default of Windows 7 the game won’t start up)).

basically I use Lutris with newest Wine (from https://wiki.winehq.org/Ubuntu ; I use the ‘stable’ one and after that’s done I issue ‘sudo apt install wine-desktop-files’ which gives you the entries in the Mint menu to configure Wine if needed) paired with the GloriousEggroll custom runner for Lutris (i.e. https://github.com/GloriousEggroll/wine . m/releases ; currently you would download «wine-lutris-GE-Proton7-22-x86_64.tar.xz» and extract it to «

/.local/share/lutris/runners/wine/» and then Lutris should automatically use it. if not, you can force it on the games shortcut in Lutris by right clicking it, select Configure > Runner Options and under ‘Wine version’ you can select the Lutris runner from the drop down menu) and then just make a shortcut in Lutris and guide it to the location of the games main EXE file and then play it.

but off the top of my head if you got a game installer you can probably just install the game like usual through Wine (i.e. double click the installer EXE). once installed, then load up Lutris, make a shortcut and guide it to the location of the games EXE file (which will probably be located in this general location. «

/.wine/drive_c/» ) and play it.

NOTE: to make a shortcut in Lutris it’s simple enough. start Lutris, click «+» in the top left corner, then on menu that pops up select ‘Add locally installed game’. then a ‘Add a new game’ window will appear at which point on the ‘Runner’ text to the right of that says ‘Select a runner from the list’, click that, change it to ‘Wine (Runs Windows games)’, then over on the ‘Game options’ tab under ‘Executable’ you guide it to the location of the games main EXE file (by clicking the ‘browse’). you can tweak more if you want to, but that’s the basic idea.

but looking at what you posted. it seems that «lutris-fshack-7.2-x86_64» is not installed by default. but you can install that in particular directly by going to Lutris’s ‘Preferences > Runners’ and then scroll down to the bottom and see where it says ‘Wine’ and to the right of that is two icons you can click, click the one to the right, which should then open a ‘Manage wine versions’ screen at which point you can click ‘install’ to the right of the «lutris-fshack-7.2» text (maybe if you manually install this fshack stuff first and then do your installer, maybe it will work(?)). but honestly, I suspect that GloriousEggroll runner I posted is probably better in general as with that I can run a game or two that normally don’t seem to work.

for the record. you can install certain versions of the GloriousEggroll runner from within Lutris directly if you want as they are listed as ‘lutris-ge etc’ using what I described above in that general ‘lutris-fshack-7.2’ section.

but looking online a bit for that ‘error code 256’ your getting one user suggested recently (about 4 days or so ago). «Top right hamburger menu > preferences > global options > disable lutris runtime (toggle this to off aka no orange)» and a user replied saying it worked for them for whatever this is worth.

this means your flash drive is not large enough to hold the win10 iso. i just formatted my really old 8GB flash drive which i have formatted maybe 1000 times to fat32 and i have no issue making windows usb out of it. what is the full name of your win10 iso called? are you trying to make a bootable iso from an .exe update?

did you format your flash drive with the Usb stick Formatter?

rightclick on the .iso and Open With «Disk Image Mounter» but more than likely your copy of install.esd is larger than 4GB which woeusb can’t handle. is this an official microsoft .iso?

try open gparted, select your flash drive and under devices > create new partition table > msdos > EXIT and format with USB FORMATTER NTFS

not sure if woeusb works with ntfs since it does install grub but fat32 will give you a limit at 4GB

you need to get an OFFICIAL copy of windows 10 or create the usb in other windows os with the Windows USB/DVD Download Tool

I have the same identical problem using Cinnamon 18.3, but I went further in analyzing it. I installed the Ubuntu repository for WoeUSB, and ran WoeUSB. My copy of Windows 7 Pro is the official Microsoft OEM compatible version, because I have an OEM MS Win. 7 Pro license sticker on my computer, which the local Microsoft rep guided me by phone to verify — it verified as good. Then the Microsoft rep guided me to create a bootable USB stick on a Windows 7 Pro machine I have, using 100% Microsoft software, and that procedure produced a bootable USB stick using my official MS .iso file of OEM Windows 7 Pro 64bit.
So I have a working copy of a USB stick with official MS Win 7 Pro .iso installed on it, made entirely using Windows software, not Linux, to compare with my WoeUSB. Both copies, my 100% Microsoft copy, and my WoeUSB copy are IDENTICAL on my computer screen, plugged in side by side into my computer, until the instant that the WoeUSB installation finishes, when suddenly it crashes in the last milllisecond of installation, and after that millisecond the two copies are no longer identical, but radically different!

Conclusion: THIS IS A VALID COMPLAINT, WHICH I HAVE VALIDATED AS CORRECT, needing attention by the gurus on this forum. The previous guru was wrong in his conclusions.

yum Docker install error Errno 256 Errno 14 HTTPS Error 404 — Not Found

As I have done in the past, I am trying to install docker-ce on RHEL 7(ppc64le) like this:

sudo yum-config-manager —add-repo https://download.docker.com/linux/centos/docker-ce.repo

yum repolist
repo id repo name
docker-ce-stable/x86_64 Docker CE Stable — x86_64

sudo yum install docker-ce
I get the error output below. I have tried all the solutions recommended, but I think the real error is the very last line in the error output which is:

failure: repodata/repomd.xml from docker-ce-stable: [Errno 256] No more mirrors to try.
https://download.docker.com/linux/centos/7/ppc64le/stable/repodata/repomd.xml: [Errno 14] HTTPS Error 404 — Not Found

Any suggestions on how to resolve this error?

========= Start error output ==================
https://download.docker.com/linux/centos/7/ppc64le/stable/repodata/repomd.xml: [Errno 14] HTTPS Error 404 — Not Found
Trying other mirror.
To address this issue please refer to the below knowledge base article

h t t p s://access.redhat.com/articles/1320623

If above article doesn’t help to resolve this issue please open a ticket with Red Hat Support.

One of the configured repositories failed (Docker CE Stable — ppc64le),
and yum doesn’t have enough cached data to continue. At this point the only
safe thing yum can do is fail. There are a few ways to work “fix” this:

Contact the upstream for the repository and get them to fix the problem.

Reconfigure the baseurl/etc. for the repository, to point to a working
upstream. This is most often useful if you are using a newer
distribution release than is supported by the repository (and the
packages for the previous distribution release still work).

Run the command with the repository temporarily disabled
yum —disablerepo=docker-ce-stable .

Disable the repository permanently, so yum won’t use it by default. Yum
will then just ignore the repository until you permanently enable it
again or use —enablerepo for temporary usage:

or
subscription-manager repos —disable=docker-ce-stable

Configure the failing repository to be skipped, if it is unavailable.
Note that yum will try to contact the repo. when it runs most commands,
so will have to try and fail each time (and thus. yum will be be much
slower). If it is a very temporary problem though, this is often a nice
compromise:
