I read qubes-dist-upgrade --help and this documentation: How to upgrade to Qubes 4.2 | Qubes OS

  1. Then i did (STAGE 1) Update of dom0, TemplatesVM and StandaloneVM manually:
  • via sudo qubes-dom0-update,
  • and install updates inside TemplateVMs:
    • apt update ;
    • dnf update ;
    • ā€¦ .
  1. Then run STAGE 2, STAGE 3 via qubes-dist-upgrade,
  2. Then sudo reboot.
  3. Then run STAGE 4 - with some no critical errors with some my StandaloneVMs (It might be necessary to update the QubesOS repositories from 4.1 to 4.2 by hands in StandaloneVMs.).
  4. Then run STAGE 5, STAGE 6 via qubes-dist-upgrade.

The update completed successfull!
