I deleted all my wallets (never wanted to have it enabled), went to system settings KDE Wallet and unchecked enable KDE wallet subsystem, logged out and back in, and it is still harassing me to log into kdewallet and printing The kwalletd service has been disabled to my console.
How did you configure your network security? The default is to store them into KWallet.
Could be I am not familiar with centOS default configuration, or what step I chose that. However, it seems it should be easier to disable, why should I get errors if I disable it? Is that intended functionality?
centOS ships long unmaintained KDE software. Please use Plasma 5.8 or newer.
