Tails Verification extension is broken once installed in Tails 3.6

Originally created by @emmapeel on #15434 (Redmine)

Reported by user, confirmed by me:

Steps to reproduce:

Open Tails
Go to https://tails.boum.org/install/download/index.en.html
Click I already downloaded Tails 3.6.1
Click Install verification extension
Allow / install

Nothing happens. On the journalctl I see:

What should happen

I should get a green button saying: Verify Tails 3.6.1 like in attachment.
