[SOLVED] Cannot upgrade kernel

[enboig]

Trying to upgrade fails. I checked and it is not a space problem:

The following packages were automatically installed and are no longer required:                                     
  libltdl7 slirp4netns                                                                                             
Use 'apt autoremove' to remove them.   
The following additional packages will be installed:
  proxmox-kernel-6.5 proxmox-kernel-6.5.13-3-pve-signed
The following NEW packages will be installed:
  proxmox-kernel-6.5 proxmox-kernel-6.5.13-3-pve-signed
0 upgraded, 2 newly installed, 0 to remove and 2 not upgraded.
21 not fully installed or removed.

that sounds like the deb file on disk is potentially corrupt? can you check your disk and memory health, and maybe clear out the cached APT files and retry?

 

[enboig]

I tried "apt clean", it continue failing. I decompressed cache filed with "ar x ..." and worked without an error.

It is a test server with 4gb of ram. I have discovered it don't have swap, so maybe it is a low ram issue?

 

[fabian]

please try "rm /var/cache/apt/archives/*.deb" and then retry.

Stopping containers and rebooting solved the issue; so I am pretty sure it was an "out of memory" problem.

Thanks.
