Public bug reported:
Bug: PackageKit refresh-cache fails on Ubuntu 26 Resolute with new apt backend
Paquete: packagekit 1.3.4-3ubuntu1
Sistema: Ubuntu 26.04 LTS, kernel 7.0.0-15-generic, amd64
Descripción:
refresh-cache siempre falla (error silencioso, retorna "failed" en el journal)
aunque apt-get update funciona perfecto y otras operaciones de PackageKit como
resolve
y get-updates andan bien.
Reproducir:
```python
import dbus
bus = dbus.SystemBus()
proxy = bus.get_object('org.freedesktop.PackageKit',
'/org/freedesktop/PackageKit')
pk = dbus.Interface(proxy, 'org.freedesktop.PackageKit')
txn_path = pk.CreateTransaction()
txn = bus.get_object('org.freedesktop.PackageKit', txn_path)
txn_iface = dbus.Interface(txn, 'org.freedesktop.PackageKit.Transaction')
txn_iface.RefreshCache(True) # siempre falla
```
Logs:
```
refresh-cache transaction /90_cbbdedbc from uid 0 finished with failed after
1438ms
```
Impacto: Cockpit Software Updates (tools.softwareUpdates) muestra error al
refrescar caché. Workaround: correr sudo apt-get update antes de usar la UI.
Nota: Usa el nuevo backend libpk_backend_apt.so (no el viejo aptcc).
