[vpsFree.cz: community-list] Co dělat když nestartuje LXD ve snapu / What to do when LXD from snap doesn't start

Ahoj, (English below) Pokud vám po restartu VPS nestartuje LXD, je to pravděpodobně způsobeno změnou ve snapd. Ve verzi 2.60 dělali nějaké změny s AppArmorem a aspoň v našem prostředí pak LXD nestartuje. Chyba při instalaci např. vypadá takto: # snap install lxd error: cannot perform the following tasks: - Start snap "lxd" (25505) services (systemctl command [start snap.lxd.activate.service] failed with exit status 1: Job for snap.lxd.activate.service failed because the control process exited with error code. See "systemctl status snap.lxd.activate.service" and "journalctl -xeu snap.lxd.activate.service" for details. ) Jednoduchý workaround je v detailu VPS ve vpsAdminu zrušit feature "AppArmor control directories" (aby to nebylo zaškrtnuto). snapd ani LXD se potom nebudou snažit AppArmor použít a bude to fungovat. ENGLISH: If you're having an issue with LXD installed as snap not starting, it is most likely caused by a change in snapd. Version 2.60 contained some AppArmor-related changes which do not work correctly, at least not in our environment. For example, this is the error when trying to install lxd: # snap install lxd error: cannot perform the following tasks: - Start snap "lxd" (25505) services (systemctl command [start snap.lxd.activate.service] failed with exit status 1: Job for snap.lxd.activate.service failed because the control process exited with error code. See "systemctl status snap.lxd.activate.service" and "journalctl -xeu snap.lxd.activate.service" for details. ) A simple workaround is to disable feature "AppArmor control directories" in VPS details in vpsAdmin -- uncheck it. snapd and LXD will no longer try to use AppArmor and will work again.
