This issue seems to be due to a problem with the file /var/lib/apt- xapian-index/cataloged_times.p -- perhaps it's an invalid value or some file corruption that is resulting in the cPickle.load command failing to deserialise the file.
In my case I simply renamed this file, re-ran the index process (sudo /usr/sbin/update-xapian-index -u -f) and the issue appears to be resolved. I'll need to leave it a few days to let this run through cron in order to be completely sure. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/971864 Title: ValueError: could not convert string to float: k_latency=0.850 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/apt/+bug/971864/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
