Description dominik.klementowski 2024-02-19 11:56:36 UTC 
SUMMARY
Using kup-0.9.1.20231221-1 with Arch Linux and kde-unstable Plasma 6.0. 
Trying to setup backup to manually mounted additional internal harddrive. It's regular ext4 with just one directory for backup with ownership set as my user (1000).
When selecting "Destination" I switch from "External Storage" to "Filesystem Path" and then choose my `/mnt/backup/xyz` directory. After pressing Apply I get a popup window with message "Backup plan 1 does not have a destination! No backups will be saved by this plan.". When I close the settings and reopen it, still "External Storage" is selected, and changing to "Internal Storage" shows that it saved my provided path, but not the fact that I want to use internal storage itself.

When running systemsettings from terminal it throws some clues:
```

```


STEPS TO REPRODUCE
1. Install kup, go to systemsettings -> backups
2. Create new plan, in "Destination" switch the radio button to "Filesystem Path" and choose a directory
3. Apply

OBSERVED RESULT
Backup cannot be created due to "no destination"

EXPECTED RESULT
Should work

Port away from QSignalMapper::mapped signals

These overloaded signals were removed in Qt6. Qt5.15 contains the
replacement signals, same as qt6.
