ack-grep is already the newest version (2.22-1)

but ack-grep gives

ack-grep: command not found

It was working fine in Ubuntu 16.04, before upgrading to 18.04

Answer 1

ack-grep is a meta package to pull ack in 18.04.

Try to do sudo apt install ack and execute ack instead of ack-grep ; that's a proper command.
