I was able to remove the apt-get errors by doing : sudo /etc/init.d/acpid stop dpkg --configure -a
But I still have the errors in log files ( dmesg attached ). And at exit, most of the time ( not every time ) the system froze with the fans going full speed instead of shut down. ** Attachment added: "dmesg" http://librarian.launchpad.net/5102317/dmesg -- Multiple ACPI related issues after upgrade Dapper > Edgy https://launchpad.net/bugs/71465 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
