Error verification failed 15 access denied

Since today when I start or restart my PC I immediately get a blue screen which says:

Verification failed: (15) Access Denied

I press return to enter «OK» and get another blue screen called «Shim UEFI key management».

I am given 3 options: Continue boot; Enroll key from disk; Enroll hash from disk

If I select enroll key/hash I get a long list — I’ve tried selecting some of them but the key cannot be found [message: Only DER encoded certificate (*.cer/der/crt) is supported].

If I select continue boot I boot directly into Windows 8.1 (64-bit) despite my system being dual-boot with a Linux distribution (and working with both Linux and Windows perfectly well until today). Every time I boot or reboot I have to go through this same sequence and can only boot Windows.

Possiblly important additional info:

1) I have been invited to upgrade to Windows 10 but have not done so yet — I’m «hiding» the 8.1-> 10 upgrade option;

2) yesterday (i.e. just before this problem appeared) the HP Support Assistant updated «HP PC Hardware Diagnostics UEFI» to version 5.8.2.0

Has any UEFI expert any tips to overcome this Access Denied problem and/or tell me how to enroll the key which appears to be lost for some mysterious reason?

How to fix Secure Boot error «Image failed to verify with *ACCESS DENIED*» on startup?

When I started up my machine this morning (I have Secure Boot and UEFI only enabled) I got this error (sorry for low quality image):

What does it mean by Image failed to verify with *ACCESS DENIED* ? After I pressed OK I managed to get into my BIOS and turn off Secure Boot as well as settings the UEFI only option to accept both UEFI and Legacy, this seemed to do the trick and now it boots, however I am unable to set it so that Secure Boot is on again and this poses a security threat to me so I am wondering what the problem is here? And why I got the error? I mean, is there error something to worry about? And why did it *ACCESS DENIED* me?

The only thing that I can think of that I might have done last night before this issue this morning occurred is receive some security updates for grub and some other stuff:

So basically I need to know what the error means, why I got it, and how to fix this situation. I mean, could this error mean that I have been compromised in some way and should do a fresh install or something? Or is it just a malfunction? And if so, how do I fix it so that I can use Secure Boot again?

I am running Ubuntu GNOME 15.10 with GNOME 3.18 on a Lenovo B590.

Information Update:

The output from the command efibootmgr is:

According to https://bugs.launchpad.net/bugs/1528345 this was caused by Ubuntu shipping security updates for grub in an incorrect way, and can be fixed by installing the package grub-efi-amd64-signed, and then reenabling secure boot in the BIOS. This worked for me. (I also checked that reinstalling the package caused shimx64.efi to show up in the output of efibootmgr -v instead of grubx64.efi , which was there while the problem was present.)

First, go back into your firmware and disable the CSM («legacy boot») support. If you were booting in a pure-EFI environment, as it sounds like you were, that option will do you no good, and could come back to bite you later. (See my page on the subject for more information on CSM’s problems.)

Second, the error message indicates that your computer attempted to boot a boot loader that was not signed with an authorized Secure Boot key. (Some of the messages warning of such violations are pretty obtuse — they vary from one EFI to another, and in some cases from one follow-on program to another, depending on where the violation occurred.) Such a message popping up after the computer has been booting successfully, and with no changes to your boot programs or firmware settings, is a big red flag.

I saw no mention of updates to either GRUB or Shim, so your boot process should not have been affected by those updates. OTOH, it could be that something else has modified the boot path. This might be an innocent change that’s gone badly and caused a glitch — for instance, if you’re triple-booting with another Linux distribution, it might have changed the boot path to an unsigned GRUB. If that’s the case, you can change the boot order back to Ubuntu’s GRUB (via Shim) with efibootmgr — type sudo efibootmgr -v to see the current boot order (on the BootOrder line) and options (the bulk of the output). Locate the line for Ubuntu that launches via Shim and use the -o option to change the order so that it’s first, as in sudo efibootmgr -o 0009,0000,001B if the desired entry is Boot0009 and two alternatives are Boot0000 and Boot001B . Another possibility is that an unrelated Windows update has interfered with GRUB. (Microsoft has the ability to update most computers’ Secure Boot keys, and if they’ve bungled that or deliberately blacklisted Ubuntu’s Shim for some reason, you might see the error you’ve described.)

There’s a small chance that something malicious is happening — some piece of malware might have installed itself in your boot path. If that’s happened, then by disabling Secure Boot, you’ve already enabled the malware to run. There’s no telling what the consequences might be if this is the case. I don’t mean to alarm you; the odds of this having happened are low. If this has happened, though, it will take expert TLC to recover your computer, since pre-boot malware is notoriously difficult to extricate.

Updating your GRUB configuration is unlikely to do any good, although there’s a slim chance that it might if you switch GRUB from booting an unsigned to a signed version of the kernel. (The last I checked, Ubuntu’s GRUB would boot unsigned kernels, but that might change in the future. Some other GRUBs, like the one used by Fedora, are stricter and will boot only signed kernels.)

You can check your boot path with efibootmgr and verify that it’s booting through Shim by default — that is, the boot loader for the first item in the boot order should be EFIubuntushimx64.efi . If that’s not the case, then you may be able to change the boot order back. If it is the case, then perhaps your shimx64.efi binary has become damaged (or worse, replaced by malware). Completely re-installing GRUB might fix the problem. (Boot Repair can do this fairly easily.)

Как разблокировать аккаунт после 5 неудачных попыток входа

Как разблокировать аккаунт после 5 неудачных попыток входа

Наверное, каждый сталкивался с ошибкой при попытке авторизации с не валидными данными, которая по-английски звучит так

Sorry, there have been more than 5 failed login attempts for this account. It is temporarily blocked. Try again later or request a new password.

Аккаунт временно заблокирован по причине более чем 5 неудачных попыток входа. Попробуйте войти позже, или запросите новый пароль.

Это простая самооборона Друпала, которая активируется после 5 (по умолчанию) попыток входа. Таким образом, система не позволяет злоумышленникам забрутофорсить (англ. brute force. Cм. Полный перебор) сайт. Работает она достаточно просто: во время каждой авторизации, Друпал сохраняет ip-адрес пользователя, запоминая при этом, точную дату события и дату окончания «срока годности» попытки.

Вот некоторые нюансы:

• По умолчанию «срок годности» составляет 1 земной час.
• Количество возможных, неудачных попыток входа — 5.
• Эти значения могут быть изменены.
• Вместо ip-адреса может быть сохранено имя хоста.
• Данные, у которых истек «срок годности» очищаются только по крону.
• Вы можете войти в систему, в любом случае если пройдете процедуру «Сброса пароля»!

Вот еще один интересный факт:

Вы можете имя пользователя указать верно, но при этом 5 раз ошибиться с паролем. В таком случае, попытки авторизации будут запрещены на 6 часов. При этом, через 60 минут можно будет повторить попытку входа, но с другого ip-адреса.

Что касается простых смертных — мы разобрались. Администраторы, же или программисты могут сталкиваться с этой проблемой чаще, т.к. им хлеб в рот не клади, дай только что-нибудь сломать. К счастью, для тех у кого есть доступ к Драшу или напрямую к базе могут обойтись без сброса пароля или часового ожидания. Нужно просто почистить таблицу flood
. Вот восемь способов это сделать.
