Concerning: kubuntu-devel-release-upgrade Sorry I don't know what component this should go under. On two separate systems using this application, upgrading 15.10 to 16.04 locked up while configuring MIME types. If there's an error message, I don't know enough to know where to look. I realize this is a BETA upgrade -- but might affect official upgrade when released? Reproducible: Always Steps to Reproduce: 1. kubuntu-devel-release-upgrade Actual Results: Upgrade locks up configuring MIME Types. Expected Results: An upgraded system. In order to avoid a completely borked upgrade (If someone else stumbles on this): 1.) Logout. 2.) CTRL+ALT+F1 (TTY) 3.) (Login) 4.) sudo rm /var/lib/dpkg/lock 5.) sudo dpkg --configure -a 6.) sudo apt-get autoremove 7.) sudo apt dist-upgrade (normally nothing needs updating) 8.) sudo apt-get autoclean 9.) shutdown -r now
