Addition: after killing the frozen installer gui and running 'sudo dpkg --configure -a' in terminal to continue the installation manually, I indeed got the prompt about /etc/tomcat7/server.xml and whether I want the maintainer's version, the current version, to view diff, etc.
However, after selecting 'n' to keep the currently installed version, a whole new full-screen dialog immediately showed up (full-terminal, that is, i.e. an ascii dialog within the terminal window, not another GUI desktop window) asking me basically the same question again but with a couple more available options (3-way merge etc.). Maybe that's what trips up the installer - the configuration file choices prompt being presented twice in a row. I hope this helps. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1509655 Title: installer crashed on custom configuration file dialog To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubiquity/+bug/1509655/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
