I looked into this a bit more. I have two drives which both had EFI partitions on them . However one of the EFI partitions was empty and was actually unused. I deleted the empty EFI the partition and I didn't get this bug and partition manager stopped crashing.
The unused EFI partition was on the Samsung SSD drive. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1567462 Title: Identical mount points for two file systems error To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubiquity/+bug/1567462/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
