Installed my printer (Brother HL-L2350DW) drivers along with CUPS. Printer added successfully and works.
However, every time I click “Manage Printing (CUPS Web Interface)” in start menu, error is displayed:
Error - KIOExec
A folder named /home/myusername/.cache/kioexec/krun/3442_0 already exists
Number (3442_0) is different every time, and this error comes even if I delete whole /kioexec directory before running CUPS. Searched the Internet for this error and found some complains, but they were related to different apps. That is to say, other people get this error with random apps - FireFox, Dolphin, etc. Some of them were solved by updating apps themselves. However, I have the latest version of CUPS, so there’s nothing to update.
CUPS itself works if I type localhost:631 into browser, but entry in start menu always displays this error.
