I can’t post in topic LXD?
Since LXD is no longer under the Linux Containers project, it was stated here:
When it comes to this forum, the LXD section will be reconfigured to not allow new topics.
Existing topics will remain active and replies can be posted inside of them. New topics related to LXD posted to other sections of the forum will be redirected to the Ubuntu Discourse instead.
The context behind all of this is on the same link above.
