Here's more detail: I clicked on the update icon and allowed 102 new packages (120 MB) to install. When everything was downloaded, I looked at the screen and saw the error message I posted above.
After looking again at the message, I decided to try again but this time "unchecking" the libc6 package a couple other files (libc6*) also automatically were deselected. I continued the install and in a few minutes it was complete. I went back to the update icon and in that 20 minutes there were more updates in addition to the lib6c packages (11 total). I Continued that update and in a few minutes Ubuntu asked me to reboot to complete the upgrade. I did and everything seems fine. Could this have been an install order problem? -- Update Manager failiure on dist-upgrade https://launchpad.net/bugs/78656 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
