However, Ubuntu 16.04 (xenial) reached end-of-standard-support on April 29, 2021 which was almost three years ago. Please only install supported releases of Ubuntu. See this document for currently supported Ubuntu releases: https://wiki.ubuntu.com/Releases I'm closing this as 'Invalid' as you don't appear to have found a bug in a supported release of Ubuntu. ** Changed in: ubiquity (Ubuntu) Status: New => Invalid -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2063011 Title: disk crashed To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubiquity/+bug/2063011/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
