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

2020-08-05 Thread Anthony C
The root cause of the problem [is in libseccomp
When][1]. The newer version fixes the problem, but it is not yet available in 
Debian's stable repos. There are two way to fix this problem:

**Method 1**

Start the container with `--privileged`. This bypasses docker's security
measures, so it is not recommended.

**Method 2**

Upgrade libseccomp manually. Dowload version from unstable repos (I
tested with 2.4.3-1) [here][2].

Uninstall the current version:

`sudo dpkg --force-all -P libseccomp2`

Install the new version:

`sudo dpkg -i libseccomp2_2.4.3-1+b1_armhf.deb`
