[SOLVED] Failed to start VM: failed to remove default vlan tags of tap104i0 - command '/sbin/bridge bridge vlan del dev tap104i0 vid 1-4094' failed: exit code

[blackwarp]

After updating latest testing PVE packages I got the following error:
Object "bridge" is unknown, try "bridge help".
failed to remove default vlan tags of tap104i0 - command '/sbin/bridge bridge vlan del dev tap104i0 vid 1-4094' failed: exit code 255

kvm: network script /var/lib/qemu-server/pve-bridge failed with status 65280
TASK ERROR: start failed: QEMU exited with code 1

Workaround:
Change the following in /usr/share/perl5/PVE/Network.pm:

Hi Fabian,

is there a workaround for those who have already executed the update?

apply the following diff (identical to original post here) https://git.proxmox.com/?p=pve-common.git;a=commitdiff;h=16cecc0dcca2c37479c72956aae8ae81cfab1bb5

to /usr/share/perl5/PVE/Network.pm and restart pveproxy and pvedaemon . updated libpve-common-perl 6.0-21 should be available soon.

libpve-common-perl 6.1-1 is available via pve-no-subscription and fixes the issue!
