OK. (It is a shame boot.log is not rotated to retain old versions.) I fixed my boot issue and I still see the message - I did not need to reinstall.
BTW In case anyone is here for a boot problem ;-) In my particular case I installed lxc-android-config without checking what it was because it contained a file mentioned in a HOWTO I was trying to follow. Uninstalling it and redundant dependencies did not fix the problem because many files remained on my system. Files in these directories could have caused the problem AFAIK: /etc/apparmor.d/ /etc/dnsmasq.d-available/ /etc/init/ /etc/rsyslog.d/ /etc/system-image/ /etc/udev/rules.d I fixed manually by searching for files on my system only provided by the packages I wanted removed (according to apt-file list and apt-file search and using some bash glue). Then I removed them to a backup tgz. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1273261 Title: Cryptsetup error during boot: /scripts/local-top/cryptroot: line 1: can't open /dev/mapper/ubuntu--vg-root: no such file To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/cryptsetup/+bug/1273261/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
