I'm affected by this bug, too, and I confirm that @raczkow patch solves the problem -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1901648 Title: docker.io package: cannot stat /var/lib/docker.migrating/* To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/docker.io/+bug/1901648/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1901648] Re: docker.io package: cannot stat /var/lib/docker.migrating/*
I have the same problem with a ZFS-based docker deployment.
The issue in my case seems to be, that
/var/lib/dpkg/info/docker.io.postinst assumes/hard-coded, that the
docker content should be located under the the /var/lib/docker
directory. It then tries to migrate this off into a separate dataset.
Too bad: I already created a dedicated ZFS dataset for Docker on my own.
And it's also in a different place: My /etc/docker/daemon.json has the
following content
{
"data-root" : "/srv/docker"
}
And this is also already a separate ZFS dataset:
# findmnt -n -o SOURCE /srv/docker
z4tank/docker
Looking at the docker.io.postinst file, the problem is that it hard-coded
always assume /var/lib/docker and does not respect a potential diverting
"data-root" setting:

@raczkow @etjohns2 : Do you both share something from my setting? i.e. a
preconfigured ZFS dataset or a non-default data-root configuration?

I've found this bug too.
It fails on postinst script. I've checked it and I'm wondering why does it try
to create zfs dataset when it already exists?
When I applied this patch, everything works OK:

This should probably be filed under the docker.io package instead of ubuntu-release-upgrader. ** Package changed: ubuntu-release-upgrader (Ubuntu) => docker.io (Ubuntu) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1901648 Title: docker.io package: cannot stat /var/lib/docker.migrating/* To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/docker.io/+bug/1901648/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
