Hi @mczurylo
Thanks for your kind help!
I do not want to use docker because I need simple gui.
The reason why I would like to build docker on debian is because I am working on debian and I want to package the binary from docker to my debian desktop.
I tried to build root directly on debian. However, I am not sure why I always encounter the issue
Module libc not found.
I built v6.28.06 last year and there was no such warning. I tried to upgrade to secured release and now I face this problem. The warning message event shows up for v6.28.06 now which is weird. I guess it is related to changes in my debian environment. I do not have an idea how to reproduce this separate issue. Similar issues were also asked in the fora but never answered. See Module libc not found
When I build on fresh debian docker, there is no issue about libc not found. However, I have issue to isolate install from build.
