I'm re-testing fedup f20->f21 this morning. I get:
sudo fedup --network 21 --product=nonproduct ... getting boot images... .treeinfo.signed | 1.8 kB 00:00:00
Downloading failed: invalid data in .treeinfo: File contains no section headers. file: /var/cache/system-upgrade/.treeinfo, line: 1 '-----BEGIN PGP SIGNED MESSAGE-----\n'
F21 tree is not published yet, so this is partly expected not to work yet... however, I wonder whether having the treeinfo signed will break fedup or not. Will, any help here?
