I know that the interim releases had issues with zfs and trying to update gave the message "Sorry, cannot upgrade this system to 25.04 right now System freezes have been observed on upgrades to 25.04 with ZFS enabled. Please see https://wiki.ubuntu.com/PluckyPuffin/ReleaseNotes for more information. "

The release notes don't seem to mention zfs. I hope these issues have been fixed?
