Ubuntu 19.10 missing dependency

I tried to run the appimage on a clean Ubuntu 19.10 installation, but it printed the following error:

error while loading shared libraries: libgtk-x11-2.0.so.0: cannot open shared object file: No such file or directory

The solution is to install the missing package libgtk2.0-0 with the following command:

sudo apt install libgtk2.0-0

This is quite an easy fix, but is annoying for people which are not very experienced with linux. Can't the libgtk2.0-0 package be included in the appimage file or at least described as a pre-install requirement?

 

Also libssl1.0.0 was needed

wget http://archive.ubuntu.com/ubuntu/pool/main/o/openssl1.0/libssl1.0.0_1.0.2n-1ubuntu6_amd64.deb

sudo dpkg -i libssl1.0.0_1.0.2n-1ubuntu6_amd64.deb
