[SOLVED] lxc don't start after upgrade from 5.4 > 6.0

HI,
you can try to figure out what the problem is by running the container in foreground mode,
`lxc-start -n ID -F -l DEBUG -o /tmp/lxc-ID.log`
where ID is the container ID.
 
is that the problem?
Code:
lxc-start 106 20190718125730.153 INFO     conf - conf.c:run_script_argv:356 - Executing script "/usr/share/lxc/hooks/lxc-pve-prestart-hook" for container "106", config section "lxc"
lxc-start 106 20190718125730.580 DEBUG    conf - conf.c:run_buffer:326 - Script exec /usr/share/lxc/hooks/lxc-pve-prestart-hook 106 lxc pre-start with output: unable to parse version info 'bullseye/sid'
 
My temp solution:
Mount the lcx and edit /etc/debian_version from "bullseye" to "buster" and they started successfully

Sorry for the double post in english/german
