Answer 1

The issue has been resolved.

1- First, uninstall all installed packages. sudo apt remove --purge --autoremove *dotnet*

2- create preference sudo nano /etc/apt/preferences

3- add these lines

Package: *net*
Pin: origin packages.microsoft.com
Pin-Priority: 1001 

4- reinstall .net sudo apt install dotnet-sdk-8.0

5- update (bashrc) nano ~/.bashrc

6- add below PATH

export PATH="$PATH:/usr/share/dotnet"
export PATH="$PATH:~/.dotnet/tools/"
export "DOTNET_ROOT=/usr/share/dotnet"

Answer 2

For any asdf users out there, this is enough to get dotnet ef to work:

export DOTNET_ROOT=`asdf where dotnet-core`

Currently that sets it to /home/<user>/.asdf/installs/dotnet-core/8.0.100
