This morning it took me an hour to get Eduroam working. Eduroam is the international WLAN roaming service for university students and staff. I brought in my (non-university managed) laptop to work and tried to get connected. I finally found the instructions on the IT Helpdesk site on place place 19 (from 21 results shown on the first page when searching for "Eduroam Linux"): https://helpdesk.it.helsinki.fi/en/instructions/logging-and-connections… As usual, the instructions are from many years back and do not work anymore on a "recent" system such as Ubuntu 20.04 LTS. On top of this, I had some old, dysfunctional Eduroam settings lingering around from a previous failed attempt. In order to make it work, I had to do the following things:
- Modify the installer script to make run at all (you need to change the first line of the installer stript changing "python" into "python3"
- Delete my pre-existing configuration by going to WiFi settings > Eduroam > Forget
- Remove the directory ~/.cat_installer
If you had multiple failed attempts, it might also be a good idea to restart your networking (or simply reboot your computer after doing the above additional steps). When I encounter outdated or wrong information on the IT Helpdesk site, I occasionally respond to the offer "How would you improve these instructions" by giving feedback, hoping to save others some time. However, during the last 5 years, I have never received any other answer except something like the following:
We have processed your support request "Feedback form for the Helpdesk instructions portal". Actions: Sadly, we have very limited resources. We are constantly improving the Helpdesk site, but adding instructions for this case exceeds our possibilities.
