Please do not update until further Notice!
The install of grub* 2.04-9 could lead to a unbootable system

Bitte vorerst keine Updates!
Vermutlich führt die Installation von grub* 2.04-9 zu einem nicht startfähige System

Background: BootHole. Fixes for that are coming in and they are broken!

If you have installed the grub-packages with version number 2.04-9, please report.

If this was this morning (what time zone is the forum clock on) I rebooted after DU ( new kernel ) I am on Grub 2-04-9 . However I will leave PC on until fix appears.

[devil]

This is just a precaution, because other distros like Ubuntu, Red Hat  and Debian Stable are having problems.

[tranquil]

Darn, I need to remember to check here before upgrading. I've already upgraded one of my computers. Hopefully the Grub upgrade doesn't hose my system. Thank you for the warning.

[devil]

After some more investigation it seems that this only fails with secure boot signed kernels. Ours is not. Others liked Debian, Ubuntu, Mint and others are. I set up a test system and it rebooted fine after the upgrade. So siduction is safe, but Debian is not, from what I hear.

Here is some more information on the bug and it's handling: https://www.debian.org/security/2020-GRUB-UEFI-SecureBoot/#buster_point_release

@devil


after a grub update my system boots ok


BUT I loose my internet connection.............................


This is after only updating grub without any other updates.

[devil]

I doubt, loosing your connection is related to this bug. Please completely dist-upgrade your system and see if connection is back.

I haven't tried updating siduction, but there was a grub update 2 days ago and a regression fix update today in Buster so presumably it would be good in sid now also.

[charlyheinz]

I' ve just run a DU and everything is working nice... .
- grub2 2.04-9 installed

[eriefisher]

Confirmed after yesterdays d-u. Grub 2.04-9. Reboot was good.

[devil]

pjnsmb, you can update grub now and if the problem persists, open a new thread for it.

As always thanks for your help and advice.


I will leave my explanation of the answer to my problem on this thread to help anyone else searching the forum for a similar boot problem :


After I updated grub to  2.04-9 I kept getting this line repeated in terminal after  using 'apt update':


Failed to fetch http://httpredir.debian.org/debian/dists/unstable/InRelease  Something wicked happened resolving 'httpredir.debian.org:http' (-5 - No address associated with hostname)


After a forum search I found out this appeared to be a DNS problem and on investigation realised that as part of the grub updates it was updating network manager settings.
I use dnscrypt-proxy for my dns and have added the advice :


'edit the file in /etc/Networkmanager/NetworkManger.conf and add "dns=none" under the [main] section'
[/size]to stop my resolv.conf file from being altered.After removing this line apt worked properly again.
