Comment 13 for bug 1938650

This seems to be a regression (deprecated AF_ALG RC4 support) in the linux-hwe-5.11 stack: https://lkml.org/lkml/2020/8/4/512

A workaround exists by either using Linux 5.8 or using a newer iwd version (e.g. from https://launchpad.net/~slyon/+archive/ubuntu/iwd+nm )

Unfortunately, we cannot easily backport a big version jump of iwd into the 20.04 stable series, but we would need a small patch that only backports the required iwd RC4 implementation on top of iwd-1.5.
