This is likely because you have a file called 'install-info' in /usr/local/bin/ that dpkg is trying to use instead of /usr/sbin/install- info which is a part of dpkg. In the event that this is infact the case you can work around this issue by creating a symlink in /usr/local/sbin to /usr/sbin/install-info:
ln -s /usr/sbin/install-info /usr/local/sbin/install-info Debian is removing the install-info script from the package dpkg which should avoid issues like this in the future. -- package m4 1.4.11-1 failed to install/upgrade: subprocess new pre-removal script returned error exit status 1 https://bugs.launchpad.net/bugs/389330 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
