Thanks for this addtiional information. Can you please run: $ /usr/lib/update-notifier/apt-chk ; echo "" and attach the result here in a situation when update-manager has updates, but no icon shows up?
Can you please please run: $ ps ax |grep update-notifier and check if you have a "notification area" applet in your panel. thanks, Michael ** Changed in: update-notifier (Ubuntu) Sourcepackagename: update-manager => update-notifier -- update-manager doesn't detect updates available https://launchpad.net/bugs/94078 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
