Tails Installer 5.0 proposes to upgrade even if the destination stick is already up-to-date

Previously the user would choose themselves in the splash screen what operation they wanted to do, so if they selected “Upgrade” they would not be surprised when they were proposed to upgrade the destination stick, even if it was already up-to-date.

Now, we autodetect that the destination device already has Tails, and when it’s the case we automatically propose the user to “Ugrade” it, which has been confusing for at least one user.

I don’t know how severe this is. I would suggest asking Help Desk if they got reports about it. Feel free to triage this out of #9005 (closed) if you want.

The aforementioned report suggests solutions, not sure what they’re worth. Note that fixing this might be tricky, in particular when one considers the case when the destination device has a nightly build installed (it’ll always tell it’s the next version of Tails, while it’s older).
