Searching the internet for libidl0, the only program I can find so far is terminator, and possibly virtualbox, but Iām not sure about that one.
Naturally, me being me, I had to try them out to see what happens. Synaptic Package Manager warned me first that it was going to removed Kompozer and libidl0 when I installed Terminator and I went ahead with it anyway just for fun.
Sure enough, as expected it did upgrade my libidl0_0.8.14-1 to libidl-2-0 0.8.14-4 and install Terminator.
I had to remove Terminator and revert to libidl0_0.8.14-1 to re- install kompozer.
Virtual box seemed to install ok and doesnāt seem to have affected kompozer.
So the bottom line is avoid installing Terminator (a terminal program which allows splitting the pane so we can have two or four or more terminals on one screen). But if you do itās not a big problem.
