1st and 3rd pics are not unusual. You often see similar output with Qubes package updates.
2nd pic is a known issue that is fixed in Whonix 14. See:
It is not fatal to anonymity. If you run:
systemctl status systemd-timesyncd.service
You will see the process is dead ->
user@host:~$ systemctl status systemd-timesyncd.service
● systemd-timesyncd.service - Network Time Synchronization
Loaded: loaded (/lib/systemd/system/systemd-timesyncd.service; enabled)
Active: inactive (dead)
@Patrick that error message link above to “whonix.org/wiki/Dev/Design-Shared#timezone” is broken because it doesn’t exist on that wiki page.
PS Jessie is EOL as of 17 June, so I guess we don’t have long to wait for Whonix 14 ->
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).
