I'm using Ubuntu 20.04 on my Lenovo laptop, and cannot connect to public Wifi networks anymore (I used to be able about 6 months ago). However, I can connect to any network with a password without problem.
When I try to connect to an open Wifi network, Ubuntu tries to connect (I see the Wifi symbol with 3 dots), but connection does not complete. And I obtain the "Activation of network connection failed" popup message.
I read most existing discussions around similar issues but could not find a fix. Restarting the computer, restarting network manager, resetting date and time, altering DNS addresses etc. were not helpful.
Please let me know what other information I could provide to clarify. Thank you for your help!
