Ubuntu 20.04 Docker legacy bitmap issue

Host: CentOS 8
In Ubuntu 20.04 docker image cloned from docker hub, the apt command returns
: legacy bitmap isn’t available

we are facing this issue

is there any solution or workaround.

Hi. What is your environment? Host OS, architecture, Docker image? And what is the command that gives you the error message? I mean for example apt-get update or apt-get install curl. Is it happens with every package?
