do-release-upgrade to 14.10 fails

[Kevin Cole]

Initially, I had third party packages. I purged them, removed /etc/apt/sources.list.d/*, and even purged the system of the community-supported apps. Now the only packages on the system are officially supported ones.

Occasionally, I got errors about a 0xA0 Unicode decode error, which I eventually tracked to a completely messed up /var/lib/update-manager/meta-release which was an HTML file. I deleted it and let the system recreate it on a further run of do-release-upgrade. The new version appears to be good.

Well... I wish I'd known where to look before removing everything from my system. Submitting this bug report allowed me to see VarLogDistupgradeMainlog.txt which contained this choice tidbit.

2014-11-02 17:22:10,545 DEBUG blacklist expr '^postgresql-.*[0-9]\.[0-9].*' matches 'postgresql-plperl-9.3'
2014-11-02 17:22:10,545 DEBUG The package 'postgresql-plperl-9.3' is marked for removal but it's in the removal blacklist
2014-11-02 17:22:10,559 ERROR Dist-upgrade failed: 'The package 'postgresql-plperl-9.3' is marked for removal but it is in the removal blacklist.'

Manually removing postgresql-plperl-9.3 appears to be allowing the release upgrade to proceed.
