> trying to overwrite '/usr/bin/ack', which is the diverted version of '/usr/bin/ack-grep'
There never was a diversion of ack-grep to ack in the package. This error message looks a lot like a diversion done by the local system administrator, i.e. is a problem of a local, unsupported modification. Remove to local diversion (e.g. with "dpkg-divert --remove /usr/bin/ack- grep" as root) and the package will install fine. ** Changed in: ack-grep (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1610700 Title: system locks up after installing upgrade to 16.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ack-grep/+bug/1610700/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
