LXC config fails

[ricop1981]

Hi,
I've 3 nodes in cluster and today update proxmox on node 1 (no dist-upgrade only apt-get upgrade) after reboot pxt start <vmid> fails with this errors:

lxc-start: 112: confile.c: parse_line: 2340 Unknown configuration key "lxc.tty"
lxc-start: 112: parse.c: lxc_file_for_each_line_mmap: 102 Failed to parse config: lxc.tty = 2

Something is strange indeed if I run:

lxc-update-config -c /var/lib/lxc/<vmid>/config && lxc-start -n <vmid> the container start and it is running.

but If i run:

lxc-update-config -c /var/lib/lxc/<vmid>/config && pct start <vmid> the container fails and very very strange is that the files /var/lib/lxc/<vmid>/config is overwritten and restored to previously values (ie. lxc.tty=2).

Any help is appreciated.
Thank you.

no dist-upgrade only apt-get upgrade

never do apt-get upgrade only 'apt-get dist-upgrade' or 'apt dist-upgrade'

Hi, thank you for reply.
But " apt-get dist-upgrade" is safe for cluster?
Unfortunately I cannot try on develop servers, only on production. So I can try upgrade only 1 node? Or is need upgrade all 3 nodes? If I update only 1 node is this distructive for cluster?
Thank you very much.
Best regards.

yes

the recommended procudure is:

for every node:
move vms/ct away from node
upgrade node
move vms/ct back
goto next node
