Recently upgraded from Kubuntu 17.10 to Kubuntu 18.04.
In 17.10, KDE Wallet was working as expected. It stored all my wi-fi passwords, SSH passwords, etc.
After the upgrade, it started asking me for wi-fi password and SSH password.
Today, when I accessed Settings -> KDE Wallet, there was no sign of any wallet. When I tried creating a new one, I could not. The program became unresponsive.
When I launched KDE Wallet Manager, there was no wallet. I could not create one. The program became unresponsive.
How do I set things right?
