This acutally seems to be an issue with the xchat package and flwm's trigger trips over xchat's malformed .desktop file. The relevant line from the DpkgTerminalLog.txt is:
Exec key for 'XChat IRC' contains '%F', '%U' or '%D' at the wrong place A valid question is if flwm's trigger should bail out in such situations. Maybe it should just skip such files and issue a warning like the other two warnings about wrong encoding in .desktop files. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1782639 Title: package flwm 1.02+git2015.10.03+7dbb30-6 failed to install/upgrade: installed flwm package post-installation script subprocess returned error exit status 255 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/flwm/+bug/1782639/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
