[Bug 1890332] Re: apt update fails on docker arm container 20.04

[Martin]

Thanks Anthony for the workaround.

Unfortunately #Method 1 won't work when building a docker image as --privileged is not available on build :( But can be a useful workaround in some cases.
Might try #Method 2 but i'm not really into doing a package mess on my stable arm build server...

So i guess i wait some more before distributing ubuntu focal .deb
packages for my software. Stuck since April with libseccomp2 issues.
Maybe i'll release focal packages for aarch64 and amd64 as i'm not sure
if otherwise i'll be able to release something before ubuntu 20.10.

I can confirm the issues also happens on other hardware than
raspberry/raspbian. Could reproduce it on another Arm64v8 CPU running
plain aarch64 Debian Buster.
