[Pkg-utopia-maintainers] Bug#1025073: Bug persists in the latest release

[dianlujitao]

I encountered the same issue with two Debian 12 (package version: 
1.42.4-1) machines, one fresh installed and the other upgraded from 
Debian 11.

Both of them use PPPoE to connect to the Internet. After connected, 
/proc/sys/net/ipv6/conf/ppp0/accept_ra is always reset to 0 and thus no 
ipv6 address is assigned.

In addition, I tested on the latest Debian testing, with NM version 
1.42.8-1, and it also has the same issue. However, my Archlinux machine 
with NM 1.42.6 works fine. Hence, I suspect that this is a downstream 
Debian bug.
