The reason is: There are two dotnet folders on the system as follows
One symptom of these problems is that both the /usr/lib64/dotnet and /usr/share/dotnet folders are on your system.
Possible installation methods are as follows【1】
1) Remove previously existing .net packages (ensure they are not installed from the wrong repository )
sudo apt remove 'dotnet*' 'aspnet*' 'netstandard*'
< /h5>
2) Configure Microsoft’s repository to ignore .net packages
echo 'excludepkgs=dotnet*,aspnet*,netstandard*' | sudo tee -a /etc/yum.repos.d/microsoft-prod.repo
< /h5>
3) Delete the dotnet package that you installed before
rm -rf dotnet
4) Manually install dotnet package
Download .NET 6.0 SDK (v6.0.415) – Linux x64 Binaries
#1 Download the installation package
