* d/pollinate.service: ensure cache directory is recreated (LP: #1848923) -- Christian Ehrhardt <christian.ehrha...@canonical.com> Tue, 09 Feb 2021 10:57:54 +0100 ** Changed in: pollinate (Ubuntu Bionic) Status: Fix Committed => Fix Released -- You received this bug notification because you are a member of नेपाली भाषा समायोजकहरुको समूह, which is subscribed to Xenial. Matching subscriptions: Ubuntu 16.04 Bugs https://bugs.launchpad.net/bugs/1848923 Title: pollinate.service fails to start: ERROR: should execute as the [pollinate] user -- missing CacheDirectory= Status in pollinate package in Ubuntu: Fix Released Status in pollinate source package in Xenial: Won't Fix Status in pollinate source package in Bionic: Fix Released Status in pollinate source package in Focal: Fix Released Status in pollinate source package in Groovy: Fix Released Bug description: [Impact] * /var/cache is expected to be able to be cleared for a reboot without drawbacks. But the directory of pollinate is a classic cache, yet it only is created in postinst. That leads to the service failing on reboot after the path was cleared. For example the cockpit images are affected by that * The Fix for that is to instruct systemd to (if needed) create that path under the same permissions. [Test Case] * sudo rm -rf /var/cache/pollinate * sudo reboot * systemctl status pollinate Without the fix it will fail to start missing the directory (but complaining about a wrong user). With the fix it works as systemd recreates that directory if needed. [Where problems could occur] * We modify the service file, so issues would be around the /var/cache/pollinate creation/usage or the start/stop/restart of the service. [Other Info] * the postinst bits doeing the mkdir are not removed to easen backport to e.g. Xenial where this systemd feature does not exist. ---- In a standard Ubuntu 19.10 cloud image install, pollinate fails to start: ● pollinate.service - Pollinate to seed the pseudo random number generator Loaded: loaded (/lib/systemd/system/pollinate.service; enabled; vendor preset: enabled) Active: failed (Result: exit-code) since Sun 2019-10-20 12:17:10 EEST; 3 months 4 days ago Docs: https://launchpad.net/pollinate Main PID: 665 (code=exited, status=1/FAILURE) Oct 20 12:17:10 ubuntu systemd[1]: Starting Pollinate to seed the pseudo random number generator...

So (1) this is a bad error message, and (2) pollinate.service is missing "CacheDirectory=pollinate".
