Continuing the discussion from How to upgrade from PureOS 9 to 10:
For future L5 Amber user needing to upgrade to Byzantium. Here was how I got there.
I gave these instructions above a go and it just updated Amber to the latest version. I looked at the OS Release and it told me it was still PureOS 9. I went through the forums looking at what people did last year and the year before with the flashing scripts some of the commands weren’t striking correctly, so I moved on to another yet slightly similar discussion on the matter. After not having much success, I ended up going to the PureOS website and found these instruction at the bottom of the download page.
In editing the source file I ended up removing the fourth line “amber-phone” since I kept receiving errors for having it as byzantium-phone. I followed them exactly until I reached the full upgrade step where I ran into this.
The following packages have unmet dependencies:
libc6-dev : Breaks: libgcc-8-dev (< 8.4.0-2~) but 8.3.0-6 is to be installed
E: Error, pkgProblemResolver::Resolve generated breaks, this may be caused by held packages.
Along with another package throwing the same error. I was a bit overwhelmed so I tried restarting it and doing some apt commands but nothing worked so I decided to try and simply remove the package like so
apt-get remove libgcc-8-dev
After the completion of the removal I went ahead and tried the final step again which with some luck I got a prompt to choose Y or N on roughly 451 packages being upgraded. After it completed 3 packages got kept back and I decided to restart it as the instructions stated.
The boot screen showed up like a homebrew screen from an video game emulator with Debian 11 and Librem 5 popping up in the background. I went ahead an explored around the new Byzantium install but still had these lingering packages that eventually I ended up either solving with
sudo apt-get dist-upgrade
or
apt-get remove "package name"
Finally being on PureOS 10 on the L5 is absolutely exciting. The UI is stunning to say the least. It was exactly how I imagined it back when I got my L5 a year ago. Looking forward to all the new additions that are on their way. Cheers!

If anybody knows how to remove the Debian 11 image on the boot screen so that it is just the L5 Please DM me. I would like to change that.
