Description Pedro Sampaio 2022-02-17 20:25:03 UTC

KCron is a module for the System Settings application. The module identifies itself with the "Task Scheduler" user visible name. It allows users to edit crontabs (both user-specific and system-wide) in a GUI interface. The code of the module doesn't use temporary files correctly neither when
reading the existing crontab nor when saving the new one.
