This may happen if you upgrade to 2.6.x from an older version (e.g. Version 2.5.x or earlier) directly. To get the Virtual School and Encyclopedia apps back, you can follow the steps below:
- Search for “Terminal” in the search bar
- Open the Terminal and run the following command:
sudo -u app-manager eamctl ensure-symlink-farm
- Restart your computer
Now you should have Virtual School and Encyclopedia on your desktop.
