am currently running PureOS 10.3 (Byzantium) on my Librem 15v3. Have been following the PureOS updates (here) and now see that Crimson (based on Debian 12) is available.
I read that Librem 11 (armx86-64) is shipping with Crimson pre-installed.
Someone here is running Crimson x86-64 on a USB drive, but not sure which device they are using. Someone here is using on a desktop.
However, many of the issues being raised, and discouraging upgrades, are related to the Libram 5 (arm), and I understand that the delays in the release of PureOS Crimson are due to the fact that it needs support two architectures.
Is anyone running Crimson on a Librem 15 or 13? If so I assume these instructions are applicable to upgrade from Byzantium to Crimson by replacing the version names.
Not sure it constitutes a “delay” per se, but in the case of the Librem 5, I think they have posted that it requires more development because it has the added complexity of mobile functionalities, not applicable to the desktop version.
