For any issue report, you should include context information, such as:
- Host OS and version
- LXC version
- Guest OS and version
- What's the difference when your container worked.
(etc.)

Host OS is Ubuntu 20.04.1, kernel 5.8.0-23

#  lxc-start --version
4.0.2
#  lxcfs --version
4.0.3

Guest OS is Ubuntu 20.04.1

This was my first container on this Ubuntu version created with this
command:
lxc-create -t download -n eqw -- -d ubuntu -r focal -a amd64
It haven't worked since the outset.
