Confirm the bug. Have had this since a couple of days. The output from update-manager looks like this:
Traceback (most recent call last): File "/usr/bin/update-manager", line 76, in ? controler = DistUpgradeControler(view, datadir=data_dir) File "/usr/lib/python2.4/site-packages/DistUpgrade/DistUpgradeControler.py", line 128, in __init__ os.O_RDWR|os.O_CREAT|os.O_TRUNC, 0644) OSError: [Errno 2] No such file or directory: '/var/log/dist- upgrade/apt.log' -- update-manager crashes when /var/log/dist-upgrade doesn't exist https://launchpad.net/bugs/59311 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
