TASK ERROR: Not an ARRAY reference at /usr/lib/x86_64-linux-gnu/perl5/5.32/AptPkg/hash.pm line 54.

[Bl1c]

Not an ARRAY reference at /usr/lib/x86_64-linux-gnu/perl5/5.32/AptPkg/hash.pm line 54.

To fix it, add an unsubscribed Proxmox repository (if you don't have a subscription) to the end of the /etc/apt/sources.list file:

nano /etc/apt/sources.list

Add line:

deb http://download.proxmox.com/debian/pve bullseye pve-no-subscription
#monual proxmox update ref

And do:

apt-get update
apt-get dist-upgrade

After that, check if the update error in Proxmox has been resolved.
