You modified the redis-server.service file, is it actually a correct file?

what does systemctl status redis-server.service show you?

[Buvaneshkumar (buvi14)]

No,I am not modified that file
Its actually a correct file,
Installing of new apps is not possible,
It shows an error:
     dpkg: unrecoverable fatal error, aborting:
     unknown user 'redis' in statoverride file
     E: Sub-process /usr/bin/dpkg returned an error code (2)
