I tried to install tmux it went to ca. 97% and than the installation holds on and never finish. Tried it severell times. After disabling suricata pakfire installed tmux without any problem.
This happens because HTTP requrests will be hard transformed to HTTPS because of enforced HSTS by the pakfire server. Suricata does not recognize this correctly or blocks it - I have to have a closer look on this. So we need to adjust suricata or to modify the default proto for pakfire from HTTP to HTTPS ( "/opt/pakfire/lib/functions.pl" line 147 )
I do not understand what you are saying. HSTS headers are widely used. They should not cause problems. Pakfire should only be using HTTPS by now.
I cannot reproduce this any more. So I suppose this was a bad rule.
