Update 2011-08-06: BackupPC has been removed from the repo. A newer release is available in lucid-backports.
BackupPC 3.2.0 is now in the repository for both Ubuntu Lucid and Hardy. The Lucid version is taken directly from Debian sid. The Hardy version is backported from the same package, with edits to make the graphs’ fonts work (older rrdtool on hardy) and depend on samba-common instead of samba-common-bin (changed after hardy).
This version fixes the “Download Zip archive” issue in Ubuntu lucid. You no longer have to manually install an older Archive::Zip Perl module.
It’s also got a shiny new favicon, courtesy yours truly. That was a hard 10 minutes’ work with GIMP, right there. Astute readers of changelogs may believe that the developers didn’t use the favicon I submitted. But according to md5sum they did, and that is awesome.
