Did you resolve this? Make sure the root that shows up on the certificate details page is UserTrust - if it's not, it's possible someone is performing MITM on you.
If that doesn't match the value you see in the Firefox or Chrome certificate details page, please, send as many details about the chain as you can back, I'm very interested to see what's happening here considering you're not on a corp network and seeing this and even moreso because this is the Tails site, something that might very much interest some attackers...

SHA-256 Fingerprint for tails.boum.org should be:
F8:DC:67:21:96:77:46:F5:9D:77:BD:7B:87:C1:39:42:C8:4E:4B:25:97:34:AC:E2:80:24:99:35:D9:81:9C:B6

I had a bunch of work to get to today, so I just didn't have time to mess with this.
But the problems seem to have gone away.
