I haven't seen anything here for a couple of days, so I did some more experimenting after a complete reboot (to get rid of any cached files).
Trying to install kdevelop3 produces this logfile: ----- Selecting previously deselected package kdevelop3-data. (Reading database ... 139659 files and directories currently installed.)

Anyway, I hope that all this is of some use. This is a development system, and unless kdevelop works I am going to have to back WIndows/VC++ instead :-( [Much to the amusement of Windows-using colleagues, I expect] -- kdevelop will not run on 6.06-1 AMD64 https://launchpad.net/bugs/66744 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
