When Linux machines have x0rfbserver running (it provides VNC server for user's current X session, so it is not that uncommon), the Firebird's script:

scripts/preinstall.sh

checks for running fbserver/ibserver like this:

ps -efww | egrep "(fbserver|fbguard)" | grep -v grep

The problem is that "x0rfbserver" contains word "fbserver", and installer refuses to run. I had no trouble fixing it myself, but I suppose some novice users would have a hard time.

Solution:

There are various approaches to the problem. One is to use pidof, for example. Or, grep itself could be improved to detect fbserver only when it is a single word, this seems to work fine:

ps -efww | egrep "\b(fbserver|fbguard)\b" | grep -v grep
