Comment 27 for bug 1732030

Hmm,
0041 should be sys_socket

With the error present (in your case ppa enabled), could you add this and retry:

echo 'apt::sandbox::seccomp::allow { "socket" };' > /etc/apt/apt.conf.d/99seccomp

If it works with that it really was the socket call, and Julian can consider adding it.

https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=879814#15 has listed 0041 as well, and I thought it is done, but your check will help Julian for sure.
