I'm trying to install corosync on a system that already has a user 'ais' - a user that I can't overwrite or otherwise get rid of.
I'm running into the same problem as Thorsten Glaser ran into five years ago, only I'm trying to install corosync 2.3.3-1ubuntu1, on ubuntu 14.04 $ sudo apt-get install corosync ... Setting up corosync (2.3.3-1ubuntu1) ... adduser: The user `ais' already exists. Exiting. dpkg: error processing package corosync (--configure): ... My current work-around is to go into /var/lib/dpkg/info/corosync.postinst and replacing all instances of ais with ais_corosync - then I re-run the apt-get install; it works and gives me a working system, but this seems like the wrong way to do it, and I'm pretty sure I'm gonna experience significant pain next time the corosync package is updated.
