Error: Failed to import module localemod

:wave: Hallo community,

:anger: I get an error message, if I run the dom0 updater.

[user@dom0 ~]$ sudo qubesctl --show-output state.sls update.qubes-dom0

:question: Should I be worried? How can I solve this error?

:pray: Thank you very much for your help.

It has failed to load a resource for your locale. Salt Localemod docs refer to this variable…

It appears it didn’t break any other functionality based on the “Comment” and “Result” fields.

How can I avoid this error? What should I do?

Hello there,

getting the same error after upgrading to Qubes OS 4.1. I think exactly the same issue is described and marked as Solution here: Dom0 update fails after 4.1 upgrade .
After the update attempt, there’s still a green tick shown after dom0 (!) Only after opening the Details, one can see that there is an [Error ] . Is this a security concern?

Thank you!

Please note that the upgrade process didn’t ran that smooth, I unintentionally skipped Stage 2. I ran qubes-dist-upgrade --all , but Stage 1 was stuck for a while, I aborted it and “continued” manually.
I’ll try to fix the problem by myself first.

Fixed. Followed the instructions from RhizomaticNomad from from Dom0 update fails after 4.1 upgrade

in Global settings → Default kernel used by qubes was pointing to 5.4 from fc25, changed that to 5.10.109-1.fc32.

sudo dnf remove qubes-mgmt-salt-base-overrides (not necessary, because it wasn’t installed (anymore?))

qubesctl saltutil.clear_cache
qubesctl saltutil.sync_all

After this, the Dom0 could be updated again.

That’s all I did (even no reboot).

Best regards,
