Особенность: если сначала пропинговать зеркало, а потом запустить pacman — то все работает.

[SOLVED]error:failed retrieving file ‘core.db’ from mirrors.kernel.org

Today I suddenly got this error when doing ‘pacman -Syu’

I know just should take another mirror but I still wonder where the error comes from.

Thanks in advance!

EDIT: solution -> wait until mirror is back online

Re: [SOLVED]error:failed retrieving file ‘core.db’ from mirrors.kernel.org

Yep, I get this every once in awhile when I have an FTP server as my first mirror, you should rankmirror say, three or more mirrors in your list so that it falls back to another good mirror if the first one fails.

Hello archerix,
Welcome to Arch. First off, I doubt your issue is the same as the one in this thread. This thread is eight months old.
Your issue appears to be you have no network connection.

Based on that assumption, I am going to ask that you start a new thread. I am going to close this thread in accordance with our policy

Feel free to refer back to this thread if you feel it is relevant. Before you do, I suggest you see if you can ping archlinux.org or goggle.com. If you cannot, that is certainly the crux of your problem.

[Pacman] Арчепроблемы?

Попробовал несколько других зеркал, тоже не работает. При этом extra, community и multilib нормально обновляет. WTF?

Это я к чему: mirrors.kernel.org пробовали?

попробуй из этих:

Это я к чему: mirrors.kernel.org пробовали?

Тоже не работает.

Я только что поставил арч, по netinstall, и он качал пакеты из этого core. Стоило перезагрузиться, как такой вот fail.

Казалось бы причём тут пакман, тем более, что у всех, кроме тебя, подобных проблем нет.

так попробуй сгенерировать по самым быстрым зеркалам от тебя, а потом — pacman -Syy

У меня такой косяк всплывал с миррором яндекса, потом прошло само.

и да смотри настройки wget’a, curl’a или чем ты там скачиваешь.

Что в pacman.conf?

Почти всё по дефолту, только multilib раскомментировал.

pacman -Syu —debug

Дальше как обычно. На

выдаёт кучу строк, среди которых те же самые про Connection time-out и download library error.

Можно расскоментировать в pacman.conf строчку

XferCommand = /usr/bin/wget —passive-ftp -c -O %o %u

и посмотреть, что из этого выйдет.

в строчку загрузки ядра (обычно в /boot/grub/menu.lst), перегрузитесь.

О, брат по несчастью!

Можно расскоментировать в pacman.conf строчку

XferCommand = /usr/bin/wget —passive-ftp -c -O %o %u

и посмотреть, что из этого выйдет.

Теперь всё обновилось, только что это было?

Заккоментируйте взад, если ошибка повторится, то ipv6.disable=1

(Баг пакмана, есть тикет в багтрекере.)

failed retrieving file ‘core.db’ from. when connected on the wifi

I’ve just moved home today and pacman doesn’t work when I’m connected on wifi:

But no problem to update once I connect to my phone’s hotspot. Is there a rational explanation (and how to fix this problem) ?
Thanks

Re: failed retrieving file ‘core.db’ from. when connected on the wifi

Seems like a DNS problem. Can you issue `ping www.google.com` and ping 8.8.8.8 to see what happens? Can you connect to the internet at all? Can you try to force your system to use Google DNS (8.8.8.8)? Also what is the content of /etc/resolv.conf?

Not a DNS problem apparently

wlp1s0 is my network interface name.

There’s one thing that strikes me as odd : all replies are ipv4 .

Can you tell me exactly how to know if it’s enabled or not ? It seems ok according to this command:

By the way, I don’t have a file like /etc/sysctl.d/40-ipv6.conf

How can I find the link to try ? I’ve tried $ wget archlinux.mirrors.uk2.net/core.db but I guess it’s a wrong address

Re: failed retrieving file ‘core.db’ from. when connected on the wifi

Pass the —debug option to pacman to show the urls it is using.

Re: failed retrieving file ‘core.db’ from. when connected on the wifi

Will print (-p) the file locations for all packages that are in the current full system update (-u).

For packages available in the cache, this will be file:///var/cache/pacman/pkg urls, for packages that still need to be downloaded, this will be http urls that you can use to download. You can also use a package you definitely don’t have installed, in order to retrieve the correct url. The core.db will just be swapping out the last component, but I assume any file from the mirror would have the same error.

For the current version of pacman, you can now use

To get the right base url for a repo, and then append «/core.db»

By the way, I don’t have a file like /etc/sysctl.d/40-ipv6.conf

IPv6 addresses starting with fe80 are a special case, see https://en.wikipedia.org/wiki/Link-local_address .

Ping uses ipv6 by default and ipv4 as fallback or when ping is specifcally told to use ipv4 (like pinging 8.8.8.8 )
The kernel by default supports ipv6 , but your networkcard hasn’t gotten an ipv6 dhcp address .
That means you disabled it OR your router / isp don’t support ipv6.

problems with ipv6 might have to do with the timeouts.

Re: failed retrieving file ‘core.db’ from. when connected on the wifi

The last router I used worked well, I guess it means that my router doesn’t support ipv6 ? It’s the first time that I get this issue, most of the routers support ipv6, right ?
Then how to fix it ?

And I have also a small question aside my issue, why the mirror protocols are not using ssl ? I guess it’s a leak because a man-and-the-middle could modify the db file and make a link pointing on another content (locally or from internet, I guess there are further securities to prevent it, but still it’s something incertain), do you have any explanations about the http ?

It’s not of big as a risk as you’re making out. All of the packages in the official repositories are signed so it would be impossible for an attacker to get you to install an untrusted package. The worst they could do is to modify core.db so you didn’t get any updates for specific packages hoping to keep you on a vunerable version of a piece of software.

No, it didn’t «fix» anything. It just shifted the brokeness one space to the right. — jasonwryan
