This is now happening on 11.04 beta-1, updated as of today, on my Averatec 3280 laptop.
Some version information: Distributor ID: Ubuntu Description: Ubuntu natty (development branch) Release: 11.04 Codename: natty Linux cupid 2.6.37-10-generic #24-Ubuntu SMP Thu Dec 16 17:52:40 UTC 2010 i686 GNU/Linux model name : Mobile AMD Sempron(tm) Processor 2800+ cpu MHz : 1600.000 $ apt-show-versions update-manager update-manager/natty uptodate 1:0.145.10 I had this happen twice since last night. On running Update Manager, the program displayed a list of packages which had been updated (equivalent to 'apt-get update'). When I clicked on the install button, there was a long delay, and finally a dialog popped up telling me that "the daemon has died". After that, I was able to run "apt-get dist-upgrade" to complete the upgrade. I have been updating 11.04 almost daily since the beta-1 release. Regarding comment #9: Yes. Regarding comment #10: I'll do that next time I run update-manager. ** Description changed: Binary package hint: update-manager + + [ NOTE: This now affects Natty 11.04 Beta-1 as of 2010-12-21 ] While trying to update this system a few minutes ago, Update Manager showed a list of updates, and then shortly after I clicked on the button for starting the downloads, the program froze after displaying a message saying that the "deamon died".
