Problem with the installation of linux-image-4.19.0-14

[_Michel_]

Hello,

Since several days, I have a debian buster machine that tries to install the last kernel image.
And each day, it said it has already downloaded it.

(...) The following NEW packages will be installed:
linux-image-4.19.0-14-amd64
The following packages will be upgraded:
linux-image-amd64
1 upgraded, 1 newly installed, 0 to remove and 0 not upgraded.
Need to get 0 B/48.4 MB of archives.
After this operation, 270 MB of additional disk space will be used.
Download complete and in download only mode

I rebooted two times, however:

Code: Select all

# uname -a           
Linux wifi-deb 4.19.0-12-amd64 #1 SMP Debian 4.19.152-1 (2020-10-18) x86_64 GNU/Linux


And what is weird:

Code: Select all

# file vmlinuz.old   
vmlinuz.old: symbolic link to boot/vmlinuz-4.9.0-14-amd64
# file vmlinuz     
vmlinuz: symbolic link to boot/vmlinuz-4.19.0-12-amd64


So the new kernel is linked to vmlinuz.old and the old kernel is linked to vmlinuz.
What can I do? Just exchange the links?

Can we see

Code: Select all

dpkg --list | grep '^hi'

Looks like apt is in download only mode. What exact command do you run ? Any "Download-Only" option in /etc/apt/apt.conf or /etc/apt/apt.conf.d/* ?

So the new kernel is linked to vmlinuz.old and the old kernel is linked to vmlinuz.

vmlinuz-4.9.0-14-amd64 is not 4.19.0-14, it is from stretch. Why do you have such kernel in buster ?

Thanks to both of you.

Can we see

Code: Select all

dpkg --list | grep '^hi'

This returns nothing.

You're right. Didn't see the major number difference. This was actually a strech install at the beginning and I upgraded to buster last year.

I have no /etc/apt/apt.conf and:

Code: Select all

/etc/apt/apt.conf.d# grep -r Download-Only .

returns nothing.

I have few to no knowledge concerning debian. I used this to configue automatic security updates (which worked well up to now, sorry it's in french): https://geekeries.org/2016/04/mises-a-j ... reloaded=1

I use cron-apt. Of course, after upgrade, I changed all occurences of "strech" to "buster".

/etc/cron-apt/action.d/5-security

Code: Select all

upgrade -y -o APT::Get::Show-Upgraded=true


/etc/apt/sources.list:

Code: Select all

deb http://ftp.fr.debian.org/debian/ buster main contrib non-free
deb-src http://ftp.fr.debian.org/debian/ buster main
deb http://ftp.fr.debian.org/debian/ buster-updates main contrib non-free
deb-src http://ftp.fr.debian.org/debian/ buster-updates main

/etc/apt/sources.list.d/security.list

Code: Select all

deb http://security.debian.org/debian-security buster/updates main contrib non-free
deb-src http://security.debian.org/debian-security buster/updates main

/etc/cron-apt/config.d/5-security

Code: Select all

OPTIONS="-o quiet=1 -o APT::Get::List-Cleanup=false -o Dir::Etc::SourceList=/etc/apt/sources.list.d/security.list -o Dir::Etc::SourceParts=\"/dev/null\""

/etc/cron.d/cron-apt

Code: Select all

0 6     * * *   root    test -x /usr/sbin/cron-apt && /usr/sbin/cron-apt

So is the kernel version updated if you run

Code: Select all

# apt update
# apt upgrade

I can't follow that French guide (I didn't even try tbh) but see https://wiki.debian.org/UnattendedUpgrades if you want to automate the updates. I've used that method myself on the family laptop and it works well, I never have to touch the machine except for when I'm backing it up.

Did this and got that after reboot:

Code: Select all

$ uname -a
Linux wifi-deb 4.19.0-14-amd64 #1 SMP Debian 4.19.171-2 (2021-01-30) x86_64 GNU/Linux

So, I think it resolved the symptoms. Thank you.

Concerning the automation of the updates, my config is there for two years and worked until now.
As this machine is somewhat vital for my home (it manages the wifi connections), I will let this as it is.
Maybe there are some drawbacks with this guide when time comes to update the kernel. I will see and take appropriate actions if needed.

Thank you again.
