Refresh mechanism doesn't launch the latest installer version #2377

Open d-loose opened 10 months ago

d-loose commented 10 months ago

What happened?

After updating the installer and restarting it through its refresh page, the version that was shipped on the iso is launched again.

What was expected?

The latest version installed by the update should have been launched.

Steps to reproduce

  1. Start a live session from an iso with an outdated installer version
  2. Click on 'update to version ...' on the refresh page
  3. Click 'restart'
