[Bug 1874304] Re: grub-probe fails with failed to get canonical path of rpool with ZFS
I'm unfortunately not going to be able to repair the pool. Since grub- mkconfig was blocking all apt package installation, I simply added "exit 0" to the top of the script to get things working. But, this was a bad time to discover my backups weren't working. That's my fault for not verifying them. I used to have a manually created ZFS root using the ZoL documentation and replicated that back to a FreeNAS system (FreeBSD 11.3). This time I let Ubuntu create the root and apparently it added feature flags that FreeBSD doesn't so my replication system ceased working. So, it's looking like I'm just going to have to recreate the pool. I leave it up to you as to whether you want to close this issue out. I do think it'd be nice if a grub-mkconfig failing didn't get apt into a state where nothing can be added or removed until grub-mkconfig successfully runs. It may very well be the case that fixing the pool requires fetching another software package. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1874304 Title: grub-probe fails with failed to get canonical path of rpool with ZFS To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/zsys/+bug/1874304/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

** Description changed:
I've been running Ubuntu 20.04 daily builds for about a month. Within
the past several days, something broke with grub where it is no longer
able to probe my ZFS datasets in order to build up its menu. This had
been working fine, aside from the issue #1867007 I previously filed, so
I believe this is a regression. As a result of it, I'm unable to update
my kernel.
I noticed it when trying to perform a dist-upgrade, but it's
reproducible running `grub-update` on its own:
❯ sudo update-grub
[sudo] password for nirvdrum:
/usr/sbin/grub-probe: error: failed to get canonical path of

It's great that it's in 12.04, but that's not yet released. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/936143 Title: Please update openjdk7u2/icedtea2.0 to version 7u3/2.1 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/openjdk-7/+bug/936143/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
