Cannot update ADT from 22.3.0. to 22.6.1, no updates were found [duplicate]

Answer 1

Please follow these steps:

1. Help > Install new software

2. Select the ADT update site.

   There are two, one with http:// and one with https:// If one doesn't work, try the other. HTTPS is not working change it to HTTP and it will work

3. Select the developer tools section and press next.

4. You should see a dialog that says "this software is already installed, an update will be performed instead". Clicking ok will lead to 22.6.1 being installed.
