I was trying to connect to one of my home WiFi and, doing so, I simply copied-and-pasted my complicated password from the cell of my spreadsheet (LibreCalc) onto the text-box of password of the Network menu pop-out from the System Tray area.
However, the text-box not only accepted normal characters, but also control characters (whitespaces) that are invisible including the trailing Carriage Return as I copied from the cell of the spreadsheet. It was difficult to notice visually, not only because the text-box was by default masked, but also the control characters are all invisible.
The attempt of connection failed, because of incorrect password. And, information of such WiFi SSID has been automatically remembered and a profile was respectively created.
Then, I realised the problem might be because of the copied trailing Carriage Return, so I tried to change the password through the Configure Network Connections screen, but whatever way I tried through any screen, the connection never get success.
I suspected that the Carriage Return control character allowed by the text-box has somewhat screwed up my WiFi profiles configuration, which would possibly a bug and potential security issue for KUbuntu.
The issue is simple and easily reproducible, but please don't try on your actual system or it would definitely ruin your WiFi profile causing you failed to connect to such particular SSID forever. You may try on a Virtual Machine system.
Does anyone know how to fix this? Do I need to fix the underlying configuration file(s) that might have became problematic?
Many thanks.
