I have this same issue on one of my machines. I get the same output as James - i.e. it appears in ps, I am in the admin group, and I get the same output from apt-check.
What else can I check? -- update-manager icon disappeared from panel https://launchpad.net/bugs/41615 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
