This one can be closed, I found out what happened. When I installed autoconf and automake I got the above error message. After looking into it I found out that the program 'install-info' was not run from '/usr/sbin' but from '/usr/local/texlive/2008/bin/i386-linux/' which was in my PATH before '/usr/sbin.' After tweaking the PATH all works well.
Hint: Give the full path in the pre and post install scripts. -- package menu 2.1.41ubuntu1 failed to install/upgrade: subprocess post-installation script returned error exit status 1 https://bugs.launchpad.net/bugs/377028 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
