You can enable Dropbear SSH server during boot, I know it’s used to be able to enter disk encryption passwords during boot on headless servers. Presumably you could use this to display boot processes on another system quite easily with an SSH session on the system with a display. You could automate that system to monitor for available SSH sessions and start displaying it when it’s available.

News to me and I have Fedora on a dozen varied computers. Never missed a step.

Get your head out of installing apps via their websites like Windows. While it’s often possible, it’s preferable to use your distros package manager. If it’s not in the repo, try flathub. Finally, if they have an Appimage, use that, many distros will integrate Appimages automagically. All that stuff gets taken care of for you.

Last resort is what you ended up doing and having to install/update manually. I mean, it depends on the package but if you’re using a common distro like Ubuntu/Fedora/Arch, there should be a package ready to go for nearly anything that supports Linux.
