Comment 7 for bug 1870410

I can confirm the behaviour Brian's seeing on the Pi 3B on armhf and arm64 with systemd 245.4-2 from the PPA Balint mentioned (and the same error message which appears to be from a chunk of code slightly beyond where we were last time - so we're moving forward at least :).

As before, wifi is working fine on the Pi 4B under armhf and arm64. Interestingly however, the Pi 3B+ (which shares the wifi chip with the 4B but is only slighter faster than the 3B) now has working wifi under armhf, but not arm64 (same error as the 3B on arm64). I was slightly surprised at this, so I double checked it with a couple of reboots - same results each time.
