Ubuntu

Dependencies broken with updating software-properties-kde

Asked by Kósa Lajos

With latest system update including software-properties-kde, dependencies break completely.

The update removes following packages: kubuntu-desktop, muon, software-properties-kde

When trying to install them again: muon and kubuntu-desktop need software-properties-kde. Trying installing it:

Az alábbi csomagoknak teljesítetlen függőségei vannak:
 software-properties-kde : Függ ettől: python3-software-properties (= 0.96.24.32.1) de csak 0.96.24.32.2 telepíthető
E: A problémák nem javíthatók, sérült csomagokat fogott vissza.

Which means unfulfilled dependencies, because python3-software-properties (= 0.96.24.32.1) is needed, and only 0.96.24.32.2 is installable (yes, a higher version number does not fulfill the dependency - this could be the mistake?).

When downgrading it to 0.96.24.32.1:

Az alábbi csomagoknak teljesítetlen függőségei vannak:
 software-properties-common : Függ ettől: python3-software-properties (= 0.96.24.32.2) de csak 0.96.24.32.1 telepíthető

So this case software-properties-common (on which software-properties-kde depends) need the later version.

Quite strange - now the update has run again and without any issues.
However, here are the outputs, now of course without any problems.

For 'a higher version number does not fulfill the dependency':
There are cases where several packages depend on each other in a way that they must be the exact same version number.

Maybe you ran into a timing problem. The new version (...2) of these packages was only provided a few hours ago, and maybe there was a synchronization problem between the packages.

Whatever the cause was, it seems that the problem has disappeared.
I suggest that you mark this question as "solved", and in case that such problem re-appears create a new question document.

Agree, thanks for the explanation. Looks like it must have been the case.
