dotnet-sdk-5.0rc1-Ubuntu-20.10-installer

Quick and dirty edit of the dotnet-sdk-5.0rc1 installer script for Ubuntu 20.10

Ubuntu 20.10 is released next month, but the dotnet-sdk 5.0rc1 preview installer wouldn't work on it because it's not officially released, so I figured out what was required to get it working and added it to the script

It downloads and installs libicu66 dependency, and changes dpkg permissions to prevent _apt sandbox

Note: The values are hardcoded, not os-dependent variables, so it's not suitable for other distros

Instructions:

$ mkdir empty-directory && cd empty-directory 

$ wget https://raw.githubusercontent.com/averyfreeman/dotnet-sdk-5.0rc1-Ubuntu-20.10-installer/261df27fd670c052788874785ca197e7d4b0decb/install-dotnet-preview-groovy.sh

$ chmod + x install-dotnet-preview-groovy.sh

$ sudo ./install-dotnet-preview-groovy.sh

# ./install-dotnet-preview-groovy.sh

# exit

$ dotnet --info
