Help with swupd update returning 'Bus error' after downloading and extracting packages

Periodically, and usually after searching this forum for any major system update issues, I manually update with swupd (I’ve been updating this way ever since the update clusterfu*k that occurred last year).

Satisfied there were no major problems, I ran the usual swupd update command in order to update from 35210 to 35470.

After downloading and extracting the required packages swupd update fails with the following message:

$ sudo swupd update
Finishing packs extraction...
Bus error

Does anyone know what this error is and how to resolve it?
… swupd clean and swupd repair don’t help.
Any help would be greatly appreciated - thanks in advance :slight_smile:
