As with every Ubuntu release, Ubuntu 20.04 LTS comes with a selection of the latest and greatest software developed by the free software community. But after switching from 18.04 to 20.04 i faced a problem suddenly .

After few days of installation suddenly i noticed that my settings option is missing. Then when i try to solve this i found two reason for this error .

My Environment

OS: Linux / Ubuntu 20.04

Cause of this error
