help with installing packages in dpkg

[proneon267]

In miniwsl I noticed, it comes with both dpkg and rpm. I tried them both and got the following errors:

For dpkg:
dpkg: can't open '/var/lib/dpkg/status': No such file or directory
So, I took the /var/lib/dpkg/ directory from an ubuntu wsl and merged it with miniwsl, but still got the same error.

For rpm:
rpm: can't move './usr/bin/animate;b' to './usr/bin/animate': Function not implemented

After failing to installing the package, I manually placed the libraries and binaries at the correct location in rootfs, and tried to run the binary program, but I got:
-sh: convert: Permission denied
which is weird since, I am running miniwsl as the root user.

I know, from your reply of a previous issue, that this project was just for your learning purposes, but could you please help me out here? Atleast, in running the binary program, please?
