No iptables support and VPN connections don't work and no linux-image installed?
I am trying to get a VPN working on the board but it appears to simply fail without any reason given. The exact same configuration works on an ubuntu 16.04 box on my laptop, so I know the configuration is correct.
Also, iptables fails with:
modprobe: ERROR: ../libkmod/libkmod.c:586 kmod_search_moddep() could not open moddep file '/lib/modules/4.4.114/modules.dep.bin'
modprobe: FATAL: Module ip_tables not found in directory /lib/modules/4.4.114
iptables v1.6.0: can't initialize iptables table `filter': Table does not exist (do you need to insmod?)
Perhaps iptables or your kernel needs to be upgraded.
/lib/modules does not exist. Is iptables compiled in the roc kernel?
Finally, there doesn't appear to be any linux-image package installed. Do you happen to know of a guide where I could update or upgrade the linux kernel that is running on this computer?
