dotnet ef not working after the latest SDK is updated

Question

My system is: Ubuntu 20.04. zsh+ohmyzsh terminator kde

Recently when I wanted to run dotnet-ef migrations add Add_Minor_Fields I get:

Could not execute because the specified command or file was not found.
Possible reasons for this include:
  * You misspelled a built-in dotnet command.
  * You intended to execute a .NET Core program, but dotnet-ef does not exist.
  * You intended to run a global tool, but a dotnet-prefixed executable with this name could not be found on the PATH.

Then if I do: dotnet tool install --global dotnet-ef

Tool 'dotnet-ef' is already installed.

What has changed since the last time I've run this:

1. Possibly the new patch versions of SDK and ef tools are release
2. I've installed KDE

What can be the reason?

Answer 1

The location of dotnet gloabl tools should be in path

see:here

Linux/macOS: $HOME/.dotnet/tools

Windows: %USERPROFILE%\.dotnet\tools

Answer 2

Try uninstalling dotnet-ef and then installing it.
