Issue description
When I try to restore a container I get this error: “Error: In use”. I’ve been doing this rollback for about 2 weeks for internal testing and I haven’t changed anything.
The problem seems to be strongly related to the transition from version 4.0.6 to version 4.0.7:
Steps to reproduce
- lxc snapshot container snapshot
- lxc restore container snapshot
- Return this error: “Error: In use” and the container is stopped
Information to attach
- Container log (
lxc info NAME --show-log)
lxc info container --show-log
