I realize that Synaptic Package Manager isnāt included in Ubuntu MATE by default, I installed it.
Iām not sure if what Iām doing is technically correct, but hereās how I tried to investigate the potential dangers of holding back libdl0 for my own system.
Open Synaptic Package Manager
Use the search function to find the libidl0 package.
Select (hilight) libidl0 and go to the āPackageā menu and click āPropertiesā, to open a dialog box called ālibidl0 propertiesā.
Click on the āDependenciesā tab.
In the drop-down box, switch from ādependanciesā to ādependantsā, and read what programs are listed.
At the moment mine only lists libidl-2-0 and kompozer so I think Iām fairly safe for now.
However, itās worth keeping i mind that someday I might install some other new program which could depend on libildl-2-0 0.8.14-4 and might not work properly or might break my system, Iām only using my imagination and guessing. Iāll have to cross that bridge when I get to it.
I wonder if there is a better way to get a list of programs that use libidl* ?
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.
I know it's been a while since last post but I take a chance if someday someone needs a new way to have Kompozer working.
Kompozer has been protected via SNAP for the future.
NO need to install extra libraries: just install the snap: https://snapcraft.io/kompozer
I took me a few seconds to install it on my Ubuntu 20.04 (which includes snap) and it works great.
