I would apt update ; apt upgrade to make sure that there are no ongoing problems.
You shouldn’t get anydpkg errors or problems but unless you captured what those messages were, it may be difficult to progress that.
(For example, they might relate to things that you uniquely have installed, over and above the vanilla operating system, in which case they may get treated as low priority to resolve and also a viable workaround may be to uninstall the package before the upgrade and reinstall the package after the upgrade. Or they might relate to core packages and therefore represent more of a concern.)
I did save the full output, so I’ll examine the errors in more detail. Casual checking indicates they may all be related to extra packages I’ve installed. If necessary to troubleshoot, I’ll create a new thread. Thanks!
One thing I’ve really liked since switching to Crimson is that the packages in the main repos are up to date enough now that I only need two Flatpak apps vs the 6-7 I was using before.
For example, I needed the Flatpak GNOME Authenticator app before since the one in the repos was too buggy and out of date. No more :).
I have decided not to use Gnu Crimson as daily drivers, because still not ready for L5 for energy save. However Gnu Crimson is super nice like pure gtk4.
I do not want my L5 to suffer because of something that is not right yet.
Slightly more advanced: You can also use Jumpdrive + chroot to fix upgrade issues. I had to do this for a mobian upgrade when I was locked out by phosh and I could not unlock and reboot got me soft bricked.
From crimson, but why would you go to Crimson and then quick go back to Postmarket?
If you want to experience the improvements in gnu crimson, you need to use Gnu Crimson for a long time to notice them; you wont see all the fixes in a short period.
Well, I’m coming from PureOS! Before it was Bysanthium then Crimson but I begun with it! Then, due to exceeded delays I start to test other Distros: PostmarketOS + Phosh, then Mobian, then (thanks to you, I didn’t know GNU/Linux philosophy (1 file makes 1 task at the best) and DM Desktop Manager differences Gnome (Windows/Apple style (we think for you, you can’t hack/settings the system)) vs KDE the opposite very customisable),… I went back on Pmos + plasma + OpenRC… anyway trying to set my Librem 5 as daily driver and I’m an advanced user I still find obstacles in every Distro! For example I can’t use waydroid (that I need! I know I know, it’s blasphemy for you but I really need it!) I discovered that pmos stable version missing ash module that’s mandatory to execute waydroid so I was trying edge version that seems have it! Also pmos missing a modern browser well touch/phone _factor oriented! Angelfish can’t open some website that I use everyday!! Instead Firefox on PureOS is one of the best browser on the market and on PureOS is very well optimised for Librem 5! If you tried it on pmos probably you too experienced it isn’t well adapted to Librem 5 (neither both apk and flatpak)! So after your post “tons of updates” “better than Mobian and pmos”… I’m extremely curious to try it!!
Also convergence mobile <>desktop: PureOS is the best for now compared with the other Distros..
That’s it!
Hoping to use my Librem 5 as daily driver as soon as possible with huge and fast improvements (see GLESS3, software optimisations, Camera working,…) maybe for the end of 2026? Who knows? Who bets?
PS: moreover: PureOS allow to encrypt partitions, Mobian and Pmos don’t!
OT: Gnome or Kde Flame wars: First: I like both Desktop Environments. Linus ranted about Gnome. But Gnome was like Einsteins: If you can not leave any piece of it, than its perfect. Gnome is just a DE, you can Hack your Gnome with your Terminal or Shell still, because its a Computer/Open Source Software. So no, Kde is more Windows and Gnome more Apple, and if you know what you do or want, just push your shell script or your Terminal prompt for it.
Edit: I am not sure if its fair about flatpak because it is like a bloat up issues. I am just not sure if its that unstable, if some of us use cloud, storage, ddos protection, and much more before. Yes a not native distribution packet manager is some kind of overblown. But if every distribution could use only flatpak.. it would be some kind of reduction between the 3 or more package managing systems. From a higher view. So i am glad that purism use it, too.
librem5-flash-image is a script that wraps uuu and performs flashing. It can also download PureOS images. It doesn’t mangle the flashed images in any way.
