Thanks, Sorry for delay in response.
PC-Basic
I downloaded the RPM package for indicated for Fedora
https://robhagemans.github.io/pcbasic/download.html
On running the rpm package to install it the following errors were given as per the attachment.
On researching this the package site indicates that teh rpm package for Fedora and Centos was derived from the .deb package using alien. Further research suggested that the rpm package was trying to install directories already installed such as "/usr"
Using rpmrebuild I edited the spec2 file to remove the directories indicated in the attachment and generated a new rpm package.
This package installed with no errors.
On trying to open the package (clicking on the icon generated) nothing happened. No app related screen opened. Tried to run the pc-basic app via terminal and again no screen for the App opened.
I am not sure where to go from here. An ideas please.
I have not got around to looking at trying to make a snap for PC-basic or rcrpanel but I have downloaded the last Fedora build for rcrpanel in FC34 alome witht the source code. A snap for flatpack of PC-basic and rcrpanel would be great if I could find them
