Network Manager: IPv6 unchecked but nonetheless active

[q-pa]

Describe the bug
IPv6 for the network card was unchecked but it always had an IPv6 address. I had to comment out the line in /etc/rc.conf. For my wifi card the settings were correct.

To Reproduce

1. Plug-in ehternet cable
2. Check Network Manager for ethernet card IPv6 settings
3. Disable IPv6 and check if IPv6 address is assigned
4. Take a look at /etc/rc.conf and search for IPv6 settings

Expected behavior
Network Manager settings should modify system settings (here /etc/rc.conf) correctly.

OS Version:
Trident 18.12-U2-RELEASE

can you check with U7?

My wifi has IPv6 disabed, and it has no IPv6

[q-pa]

It is the same with U7. IPv6 support is not enabled, neither for wifi nor for ethernet. My wifi does not get an IPv6 address, my ethernet card (still) does.

[RodMyers]

can you post your output from the ifconfig command?

No longer a valid issue. Moving to void linux in 2020
