Description Joe Vaughan 2023-04-02 08:10:55 UTC 
SUMMARY
KDE Neon 'pkcon update' command returns incorrect status/error code when nothing is installed/updated. 

STEPS TO REPRODUCE
1.  sudo /usr/bin/pkcon refresh -p
2.  sudo /usr/bin/pkcon update -yp

OBSERVED RESULT
'pkcon update' returns non-zero (error code: 5) if no packages are updated. 
This is incorrect behaviour as this is not an error but a normal response.

Note: 'pkcon refresh' correctly returns 0 if no updates are applied to repository caches. 

EXPECTED RESULT

On any *NIX operating system a non-zero exit code indicates that some error occurred. 

No error has occurred in this instance, simply no updates to be applied (which isn't an error)
A successfully executing command should return status code 0. 

Therefore 'pkcon update' should return 0 as it is executing successfully even if no packages are updated.
