This is something that happens from time to time. The good news is, this doesn’t look like you’ve been hacked. Quite often this is something that resolves itself in time.
Taken from wiki Security_Guide
It could be a temporary Tor exit relay or server failure that should resolve itself. Check if the network connection is functional by changing the Tor circuit and trying again. Running whonixcheck might also help to diagnose the problem.
thanks for the tips! the problem decided. There is one more problem. on the picture, the arrow shows that it requires an update. how to update it? as well as the rest template or was peculiar?
This following wiki page was written for Qubes 3.2 .
If you are using Qubes 4.0, you can disregard setting a NetVM for your template VMs. (Github Qubes issue 1854)
There is also an issue with qubes-manager showing the pending updates available icon (green arrow) when no updates are available. If you have already updated Whonix templates, its most likely due to this bug.
Your earlier pics re: Fedora 26 updates and checksums not matching is also not uncommon. As to why - I’m guessing it relates to issues Qubes have had recently re: changing Fedora repos to https, or possibly network attackers at large screwing with downloads over Tor (although I don’t see how it can succeed as an attack vector, if gpgcheck=1 is applied, which it is by default).
