linux-purge is not able to purge when there is no meta-kernel installed on Astra Linux Special Edition 1.7.5.16 or 1.8.0.14

$ sudo linux-purge --list --keep=2
[linux-purge] WARNING: Using whiptail, if needed, because dialog is not

Is this Astra Linux somehow associated with Ubuntu Linux? Could you provide the debugging information produced with the --debug option as an attachment?

[Andrey Solopko (avsolopko)]

I am attaching the file "linux-purge.debug_BTP" obtained by the command "sudo linux-purge --list --keep=2 --debug"

[Andrey Solopko (avsolopko)]

How the "sudo linux-purge -c" command works.

Can you attach/paste the output of

dpkg-query -W -f '${Depends}\n${Pre-Depends}\n' linux-image-5.10-generic linux-image-5.10-hardened linux-image-latest-generic

[Andrey Solopko (avsolopko)]

$ dpkg-query -W -f '${Depends}\n${Pre-Depends}\n' linux-image-5.10-generic linux-image-5.10-hardened linux-image-latest-generic
linux-headers-5.10-generic, linux-astra-modules-5.10.190-1-generic

linux-headers-5.10-hardened, linux-astra-modules-5.10.190-1-hardened

linux-headers-latest-generic, linux-astra-modules-6.1.50-1-generic

[Jarno Suni (jarnos)]

I was expecting to also see packages linux-image-5.10.190-1-generic, linux-image-5.10.190-1-hardened and linux-image-6.1.50-1-generic, listed by the command. I wonder how your system gets kernel updates, if no meta-package depends on the latest kernel.

What is the output of

apt-cache rdepends --important linux-image-5.10.190-1-generic, linux-image-5.10.190-1-hardened and linux-image-6.1.50-1-generic

and

apt-cache rdepends --important --installed linux-image-5.10.190-1-generic, linux-image-5.10.190-1-hardened and linux-image-6.1.50-1-generic

I reinstalled the Linux kernel especially for you. Now like this:
0 AstraLinux GNU/Linux, with Linux 6.1.50-1-generic
1 AstraLinux GNU/Linux, with Linux 6.1.50-1-generic (recovery mode)
2 AstraLinux GNU/Linux, with Linux 5.15.0-83-generic
3 AstraLinux GNU/Linux, with Linux 5.15.0-83-generic (recovery mode)
4 AstraLinux GNU/Linux, with Linux 5.10.190-1-generic
5 AstraLinux GNU/Linux, with Linux 5.10.190-1-generic (recovery mode)
6 AstraLinux GNU/Linux, with Linux 5.4.0-162-generic
7 AstraLinux GNU/Linux, with Linux 5.4.0-162-generic (recovery mode)
8 UEFI Firmware Settings

Everything is working fine.

linux-purge was designed to purge kernels of Ubuntu Linux and possibly its derivatives. Astra Linux is not a derivative of Ubuntu Linux and seems to have different dependency structure and naming policy for kernel related packages, so I find it hard to support two incompatible systems.

Could you give the output of

apt-cache rdepends --important --installed --recurse linux-image-6.1.50-1-generic

for example?

I'll examine, if I can make linux-purge a bit more general to cover this case and to make it more future-proof for Ubuntu Linux.

[Jarno Suni (jarnos)]

Can you tell why linux-image-latest-generic doesn't depend directly on linux-image-6.1.50-1-generic, but via linux-astra-modules-6.1.50-1-generic?
