I have Fedora 30 installed on two computers with different packages installed. The major difference is that one is x86_64 and the other is i686.
On the x86_64 system, I can read and extract files from .iso files. But on the i686 system I cannot with an error message "Archive type not supported."
Is there some package that I'm missing between the two that provides support for reading CD images with Engrampa?
