http://linuxexchange.org/questions/2790/ubuntu-1010-update-manager-authentication-not-functioning<p>Hi;</p> <p>I'm on Ubuntu 10.10.</p> <p>Several weeks ago the Update Manager stopped functioning. When I go to click on the "Authentication" button, the dialog box will shake and then do nothing.</p> <p>Any ideas what the problem is and how I can fix it?</p> <p>Thanks.</p>enThu, 19 Apr 2012 10:49:40 -0400http://linuxexchange.org/questions/2790/ubuntu-1010-update-manager-authentication-not-functioning/2841<p>FYI, not to be lame, but 10.10 is a non-LTS version of Ubuntu and thus has a shorter lifecycle than the LTS version does (which also has better support)..... so why not put 12.04LTS on it in 7 days when it comes out on the 26th of April?</p> <p>10.10 is EOL (End-of-Life), but aside from that, you could do the following:</p> <p>sudo dpkg-reconfigure update-manager &amp;&amp; sudo apt-get update &amp;&amp; sudo apt-get upgrade.</p>RonThu, 19 Apr 2012 10:49:40 -0400http://linuxexchange.org/questions/2790/ubuntu-1010-update-manager-authentication-not-functioning/2841http://linuxexchange.org/questions/2790/ubuntu-1010-update-manager-authentication-not-functioning/2838<p>Check out .xession-errors.</p> <p>If it shakes and does nothing, that sounds like maybe your username is no longer allowed to su. Can you access other control panels that authenticate?</p> <p>You can also do from the console "aptitude update" and "aptitude upgrade". I assume that works for ubuntu.</p>peteriusTue, 17 Apr 2012 22:50:31 -0400http://linuxexchange.org/questions/2790/ubuntu-1010-update-manager-authentication-not-functioning/2838
