Having restored from backup, I restarted the upgrade from LTS 10.04. A bin problematic but I eventually arrived at LTS 12.04.5 and created backups of this version for recovery. I then started the update from LTS 12.04.5 to LTS 14.04. The first command used was 'sudo do-release-upgrade' but this fails as my locale is 'C'. The second command used was 'LANG=enGB.utf8 sudo do-release-upgrade' (to get round some insanity where the default locale is broken). This runs for some time (with segmentation faults and other errors) and then fails with a fatal error leaving the system in a broken but functional state between LTS 12.04.5 and LTS 14.04. In the attached pack.tar are the following: 1) installed-LTS-12.04.5.gz: Output of apt-show-versions before starting upgrade. 2) updmap.3rc9Fc0L.gz: Output that the log indicated may be needed. 3) dist-upgrade.tar.gz: Tar file of the contents of /var/log/dist-upgrade Hopefully, Brian and others will be ably to diagnose the issues using the attached files and provide a forward path in the near future.
