everything works, except k-package.
always terminates with "exec failed: No such file or directory"

I had the same problem, and it ended up being a corrupted /etc/passwd file - /usr/bin/konsole-grantpty can't give kpackage root privileges.

I had no idea how to fix it so I just ended up reinstalling. If you're using the User Change Howto be *very very* careful you typed all the changes to knx-hdinstall right; I suspect that's where I messed up, as everything went OK the second time.

Good luck
Andy

Addendum: DOH! After a reboot it no longer works, although /etc/passwd is OK.....
