Hello,
I’m upgrading our ABP project from version 3 to version 9. The application previously used the Lepton theme by default, but we now want to switch to LeptonX After following the documentation (https://abp.io/docs/latest/ui-themes/lepton-x/mvc) and running the installation command, the console reports that it unable to find package LeptonX them.
Below is the full log from the installation command.
