While there may be a way to upgrade, general consensus is that it’s not possible and you should reinstall.

If you’re somewhat tech savvy, don’t have anything against the high seas and absolutely need Windows, look into Windows 10 LTSC.

This is not Apple Pay for customers we are talking about. This is a feature for merchants so they can receive money on their iPhone from customers without requiring extra hardware like a card reader.

Distrobox is probably what you’re looking for.

I tried Bazzite a few months ago and replaced it with a non-immutable distro in the same day because I couldn’t get my password manager (1Password) to work with Firefox.

The installation of 1Password was kind of a hassle as there is no official way to install it systemwide on an immutable distro, so I followed an unofficial tutorial. That worked somehow, but then came the integration into Firefox. For this to work, you have to install firefox as a native package, too, so you have to layer it through ostree.

But here comes the issue: The original Silverblue does already include native Firefox, and Bazzite removed it and replaced it with a flatpak. I have googled a lot and haven’t found an answer yet on how to layer a package that was removed in a previous layer. I’m not sure if it’s even possible, but the complete lack of documentation for such a trivial thing really turned me away from immutable distros. When I had an issue on Arch, I would find the answer in the ArchWiki 95% of the time, but here I couldn’t even find a proper documentation for how the layering works.

This on top of other issues like not being able to get Autocomplete/Intellisense working in VSCode because I can’t properly install the required compilers and libraries made me turn back to Arch in a single day. Maybe it’s just my mindset that’s a bit stuck on how to do things the “old” way, but if I have to spent hours to get even a basic workflow going for me, then I guess I’m not yet ready for immutable distros.

No, LTSC only receives security updates, not feature updates.

I’m running Windows 10 LTSC with a custom start menu (StartIsBack). So far I have avoided all of Microsoft’s nonsense.

As long as I’m not ready to switch to Linux 100%, this is probably the best possible solution.

Full desktop environment with decent window tiling.

it doesn’t even host it’s own repos

Yes, and that’s a good thing, otherwise it would be like Manjaro.

EndeavourOS is perfect if you already know your way around a Linux system but don’t want to spend the time and effort to setup Arch.
