Comitup service failed to start on Banana Pi

[evandene]

I re-installed comitup what did improve but still I have errors. See below the result of systemctl status service:

pi@clearview:~ $ sudo systemctl status comitup service

I haven't tried a Banana Pi, but this should work.

iptables is used internally by Comitup to manage firewall rules between the HOTSPOT and CONNECTED states. The --icmp-type option is used to ignore host and port unavailable packets that might be thrown by a captive portal.

I would normally blame the old version of Debian used, but the command in question was added in the Jessie era.

Your problem is that the iptables command does not appear to support the ICMP extension - e.g.:

iptables -A INPUT -p icmp --icmp-type destination-unreachable -j DROP

after a full-upgrade, it looks as if the system is in a healthier position now, although I must admit that all is way above my knowledge, so hard to judge by me :-)

Not sure what it means when a moment later the status is different.

Systemd is configured to restart Comitup when it crashes, which it is doing on every startup.

It does not see the dbus interface org.freedesktop, which is pretty fundamental to proper operation.

Thanks for helping me out.
On the Banana Pi M2 Zero I installed a fresh Armbian Bulsseye OS and installed Comitup as root.
All works fine now without any error
