[SOLVED] Proxmox VE 7.2 : /usr/bin/kvm error

[remuald]

Hi,

I have an issue with /usr/bin/kvm binarie and maybe other files.

My proxmox server have been installed 15 days ago with 2 NVMe in RAID 1 ZFS and Proxmox VE 7.2 ISO.

But since last upgrade (this week) the backup feature doesn't work and after proxmox reboot, I can't start any VM.
qemu-server 7.2-3 to 7.2-4
pve-qemu-kvm 6.2.0-11 to 7.0.0-2



I have always same error :
#qm start 100
/usr/bin/kvm: symbol lookup error: /usr/bin/kvm: undefined symbol: proxmox_backup_new_ns
Command '/usr/bin/kvm --version' failed: exit code 127
Detetecd old QEMU binary ('unknown', at least 3.0 is required)

#/usr/bin/kvm --version
/usr/bin/kvm: symbol lookup error: /usr/bin/kvm: undefined symbol: proxmox_backup_new_ns

After qemu-server and pve-qemu-kvm reinstall, nothing change

Do you have any idea to fix this issue ? Or I need to completely reinstall Proxmox Ve ?

Thank for your feedback.

How did you upgrade the server? If you did it manually on the CLI, did you run apt upgrade or apt full-upgrade? Alternatively, with apt-get it should be apt-get dist-upgrade and not apt-get upgrade

Thank you for your quick answer
Sure, I have used Upgrade via WebUI interface. And after the reboot via CLI with all commands (apt upgrade, apt full-upgrade, apt-get dist-upgrade)

Hmm, what is the output of the following command?

debsums -s pve-qemu-kvm libproxmox-backup-qemu0 proxmox-backup-client proxmox-backup-file-restore

Before apply this command I need to install debsums, but the command result is :
Can't locate Dpkg/Conf.pm in @INC (you may need to install the Dpkg::Conf module) (@INC contains: /etc/perl /usr/local/lib/x86_64-linux-gnu/perl/5.32.1 /usr/local/share/perl/5.32.1 /usr/lib/x86_64-linux-gnu/perl5/5.32 /usr/share/perl5 /usr/lib/x86_64-linux-gnu/perl-base /usr/lib/x86_64-lin

BEGIN failed--compilation aborted at /usr/bin/debsums line 22.

In other hand, when I reinstall the libproxmox-backup-qemu0, I can apply with success the qm start 100 command .
"apt install libproxmox-backup-qemu0 --reinstall"

So, now, I think the issue is fixed. I have changed the type of this topic to Solved .

Thank you for this suggest.
