Get an error when installing on CENTOS7 with error message: "Invalid version flag: or" (Re-post of Desktop issue 18551)

Operating System/Distribution

Which distribution of Linux are you using? CENTOS7 Linux

Installer

Which version of the app? Which installer type?

What happened?

I followed the instructions at https://www.matthewthom.as/mirrors/#github-desktop to install Github-desktop on my CENTOS7 Linux system.

I wasn't able to import the GPG key, kept getting an error msg "key 1 import failed". I tried several workarounds, none seemed to work. Eventually I disabled the GPG checking with "yum --nogpgcheck install ..." (even though not recommended, I admit) and that seemed to go ahead. But down the line, it failed with the following error:

...
(6/6): epel/x86_64/primary_db                              | 7.0 MB   00:45     
Resolving Dependencies
There are unfinished transactions remaining. You might consider running yum-complete-transaction, or "yum-complete-transaction --cleanup-only" and "yum history redo last", first to finish them. If those don't work you'll have to try removing/installing packages by hand (maybe package-cleanup can help).
--> Running transaction check
---> Package github-desktop.x86_64 0:3.3.12.linux2-1 will be installed
**Error: Invalid version flag: or**

How do I resolve this?

i think this is the same issue #1062

Looked at it, but a solution isn't stated. What's the solution/workaround?

Additional info (that I perhaps ought to have stated before) ...

The error I get when importing the GPG key is:

$ sudo rpm --import https://rpm.packages.shiftkey.dev/gpg.key
curl: (51) Unable to communicate securely with peer: requested domain name does not match the server's certificate.
error: https://rpm.packages.shiftkey.dev/gpg.key: import read failed(2).

Any advise on how to fix this?

This is not a new issue - see https://github.com/shiftkey/desktop/issues/320 for more context.

At the time I closed that out because I didn't want to get into the realm of crafting distro-specific issues, for what is a limitation of yum: https://github.com/shiftkey/desktop/issues/320#issuecomment-1100250294

So looks like no resolution other than moving from YUM to DNF. I'm hesitant to do that lest I cause some instability in the system (as regards whatever is installed till date and whatever we may install in future).

If package-installs is so complex, is there a way I can install Github-desktop-for-Linux from source?

This isn't supported corrently. There is an AppImage version that is intended to be used standalone, independent of the installed package manager.
