Hello, I upgraded (after almost a month) two different computers with TW (KDE). Both of them were/are since then unable to connect to WiFi. Connection to any encrypted WiFi network was refused with message "No credentials provided". Going to management of network connections showed that all networks have empty credentials fields. It looks like all WiFi passwords were lost. I don't know where and which format TW/KDE stores this data and if it is recoverable. It'd be nice, but not critical. On one computer, I removed one network from the list of saved networks, but re-connecting to it using usual way via NetworkManager applet didn't work. The WiFi was back in the list with missing credentials. I entered the password in the list of networks, restarted and it worked. On second computer, I'm still struggling. Regardless what I do (I re-enter password via applet or the list of networks), I'm unable to connect, the WiFi is in the list with missing credentials. I'm upgrading my installations without automatic installation of recommended packages. Any idea what could go wrong? V.
I had that once too. I've found that earlier NetworkManager had crashed. It was automatically restarted, but seemed like it wasn't able to connect to wallet anymore. At least until I logged out an in again. https://bugzilla.opensuse.org/show_bug.cgi?id=1107197 You can check with "sudo coredumpctl list" if you have any NetworkManager core dumped. -- Adam Mizerski
