Verification for groovy: I took a 20.10 VM with current pollinate 4.33-3ubuntu1, and after booting, pollinate.service is in state failed as per the bug description. I then updated to 4.33-3ubuntu1.20.10.1.

Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how to enable and use -proposed. Your feedback will aid us getting this update out to other Ubuntu users. If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested, what testing has been performed on the package and change the tag from verification-needed- groovy to verification-done-groovy. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification- failed-groovy. In either case, without details of your testing we will not be able to proceed. Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance for helping! N.B. The updated package will be released to -updates after the bug(s) fixed by this package have been verified and the package has been in -proposed for a minimum of 7 days. ** Changed in: pollinate (Ubuntu Groovy) Status: Triaged => Fix Committed ** Tags added: verification-needed verification-needed-groovy ** Changed in: pollinate (Ubuntu Focal) Status: Triaged => Fix Committed ** Tags added: verification-needed-focal -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1848923 Title: pollinate.service fails to start: ERROR: should execute as the [pollinate] user -- missing CacheDirectory= To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/pollinate/+bug/1848923/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1848923] Re: pollinate.service fails to start: ERROR: should execute as the [pollinate] user -- missing CacheDirectory=
@Christian: Debian still needs/wants to support sysvinit. Of course init.d scripts ought to create cache directories too (like munin, mopidy, and others already do, but probably not all of them), but that will be a bit more work. FHS applies to SysV init as well, so the same reasoning still holds. Also, some postinsts seem to do legitimate work, like fontconfig which also creates an initial font cache. If you want to start an MBF, it first needs some initial discussion, or at least announcement, on debian-devel@ [1]. And then it needs checking which packages actually have that problem, as I don't think it's actually *that* many -- two dozens tops? But in general I think this is a nice goal for sure. (For the record, we have not detected any problems related to this in the Cockpit test suite on any Debian or Ubuntu image, except for pollinate) The "/var/cache/ should be removable" reference is [2], it was already in comment #9: [1] https://www.debian.org/doc/manuals/developers-reference/beyond-pkging.en.html#reporting-lots-of-bugs-at-once-mass-bug-filing [2] https://refspecs.linuxfoundation.org/FHS_3.0/fhs/ch05s05.html -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1848923 Title: pollinate.service fails to start: ERROR: should execute as the [pollinate] user -- missing CacheDirectory= To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/pollinate/+bug/1848923/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

@Martin - since you made me think about that "/var/cache should be removable without impact" I was looking around a bit and I think there would be many more packages that are possible affected.

That path is used to detect if it has run before and skip re-execution as it isn't needed anymore then. A path change might be wanted, but would either need all sorts of maintscript magic to carry from old to new location if that has happened on a given system. The option to use: CacheDirectory=pollinate is very tempting. Because if the path is there already this does nothing => no re-execution even on reboots. But if running in an environment that has cleaned /var/cache then this will ensure it is "fine again". I think we can at this time also remove the mkdir from the postinst. I'll prep that tomorrow and experiment with it -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1848923 Title: pollinate.service fails to start: ERROR: should execute as the [pollinate] user -- missing CacheDirectory= To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/pollinate/+bug/1848923/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Indeed all our images clear up /var/cache [1]. Sorry, I forgot about this bit before! An admin should always be able to rm -rf /var/cache, reboot, and get a fully working system [2]. So if the pollinate data is in any way precious, it should better be in /var/lib/pollinate then (similar to /var/lib/systemd/random-seed). So indeed it seems that CacheDirectory= will be at least *a* fix, or moving to StateDirectory= and moving the file to /var/lib/pollinate/ if it's precious. Thanks Christian for your help here! And sorry for my unnecessarily harsh words in comment #5, I should not have assumed that it was broken everywhere. 來 [1] https://github.com/cockpit-project/bots/blob/master/images/scripts/lib/zero-disk.setup#L42 [2] https://refspecs.linuxfoundation.org/FHS_3.0/fhs/ch05s05.html -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1848923 Title: pollinate.service fails to start: ERROR: should execute as the [pollinate] user -- missing CacheDirectory= To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/pollinate/+bug/1848923/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Awesome debugging Martin! but while I agree that: CacheDirectory=pollinate would in your case mitigate the issue by systemd providing that directory, it would also hide that this dir was lost at some point. The postinst of pollinate would have created that dir: root@h:~# grep cache /var/lib/dpkg/info/pollinate.* /var/lib/dpkg/info/pollinate.postinst: adduser --disabled-password --quiet --system --home /var/cache/$PKG --ingroup daemon --shell /bin/false $PKG /var/lib/dpkg/info/pollinate.postinst:mkdir -p /var/cache/$PKG /var/lib/dpkg/info/pollinate.postinst:chown -f $PKG /var/cache/$PKG /var/lib/dpkg/info/pollinate.postinst:rm -f /var/cache/$PKG/tag And only on remove it is removed, which didn't happen here: /var/lib/dpkg/info/pollinate.postrm:rm -rf /var/lib/$PKG /var/cache/$PKG /etc/default/$PKG And if we examine the groovy image that you referred at https://cloud-images.ubuntu.com/daily/server/groovy/current/groovy-server-cloudimg-amd64.img it has that path and would therefore not be affected.
