Word to the wise, back up your authentication tokens for Authenticator or you will loose them upon upgrading to Crimson.
That strikes me as a poor design.
Congratulation and thank you very much !!
So far I have not managed to upgrade. It times out on packages. I have restart the process 3 times with no luck. I guess I have to find a better internet connection. How big is the download?
It is better to download gcrimson then reburn manually, and reuse the download. I guess it is more safety in this way. I have gcrimson a year ago.
It depends on which PureOS image you are looking for, but generally < 2 GB.
OK, after 4 attempts the upgrade completed. Now the “About” in settings says “Crimson”. What is to be expected by this upgrade? Any link to a list of changes? Especially in userspace…
It is a super big update, the sound is better, more hardware acceleration, enable 4k video, the camera take better pictures and videos, GTK4 desing, LDAC, it is lot more.,…however the Framework still unaccelerated making some hot and low batt performance,
So far (a few hours after the upgrade) I see firefox has a slow start. More than 10 seconds. You feel it will not start. Its own web browser starts reasonably fast though.
I think we would need more detail on what is actually happening there. It’s certainly not a good outcome.
I also had network errors during the download. However it appears to pick up where it left off. So as long as your internet is not absolutely terrible, you will get there in the end.
Anyway, it seems you did get there in the end. So this comment only confirms that you are not the only one who experienced the problem.

I wasn’t able to use the PureOS updater because my battery wasn’t at >90%, but for the past year or so, the battery has never been able to charge over 70%.
I ended up manually updating to Crimson - Software management - Purism user documentation
Just a guess but does the charging need to be recalibrated? Try second paragraph of Librem 5 battery charge calibration - #12 by dos
Oh nice; I’ll try that. Thanks 
Is it possible to upgrade to Crimson on the Librem 5 with a USB thumb drive? I bought one just for this, put Crimson on it, and upon reboot, there’s no option to boot from the thumb drive and install Crimson.
Realistically, no.
Unless you are looking for a high degree of difficulty, it would be best to do the upgrade the “normal” way. You have the choice of reflash from scratch or in-place upgrade. Most people are going to want to do the in-place upgrade (since reflash means blowing everything away and starting anew). For an in-place upgrade you can use the supplied GUI tool.
Thanks for the reply. That’s what I ended up doing. Everything seems to work well. It’s the first time I’ve done the easy upgrade method in 15 years. Last time I did it there were problems and I wasn’t happy, so I’ve just done the full nuclear option every time since then. It’s still what I prefer, though, so I’m hoping that the Librem 5 will eventually have the ability to do that.
Of course the Librem 5 already has the nuclear option for upgrade. It’s just that you wouldn’t do it the way that you thought about doing it.
The standard nuclear option (in very abbreviated instructions) is:
Whether the Librem 5 will ever have a bootable installer I don’t know. However, if it did, it might be bootable off µSD card, rather than USB flash drive.
