[SOLVED] vncterm error

[Shawn Sivy]

I upgrade our Proxmox servers from 4.2 to 4.4 today. On one of the servers, I cannot launch a console in the PVE manager to any LXC containers either locally on the same server or a container located on another server in the cluster. It works if I lauching a console to a qemu/kvm vm. The task error I get is

TASK ERROR: command '/usr/bin/vncterm -rfbport 5900 -timeout 10 -authpath /vms/107 -perm VM.Console -notls -listen localhost -c /usr/bin/dtach -A /var/run/dtach/vzctlconsole107 -r winch -z lxc-console -n 107' failed: got unknown parameter 'keeplocale' for run_command

Any help in tracking down this error would be appreciated. I'm assuming it is a configuration setting somewhere.

I can start a console for the LXC containers if I go to one of the other PVE managers in the cluster and launch it from there.

Ok. I managed to track down the issue to the run_command in /usr/share/perl5/PVE/LXC.pm. That function call added "keeplocal" to it which wasn't on my 3 other Proxmox servers. After running pveversion -v and carefully cross checking the version, it appears that the server with the issue (coincidently the last one I upgraded this morning), had different versions for the pve-container and lxc-pve packages. After downgrading them to match the other servers, everything worked fine again.

Downgrade lxc-pve 2.0.7-4 --> 2.0.7-3
Downgrade pve-container 1.0-96 --> 1.0-94

root@hpc-moose1:/usr/share/perl5/PVE# apt-get install pve-container=1.0-94 lxc-pve=2.0.7-3

I can confirm that issue. Today morning upgrade killed web-vnc. Downgrade is helped me.

should be fixed with the last round of updates on pve-no-subscription - sorry for the hassle.
