libstrongswan-extra-plugins dependency problem with libstrongswan

[Deadolus]

libstrongswan-extra-plugins depends on a wrong libstrongswan version.
Or maybe the libstrongswan version in the package repository was wrongly compiled/distributed.
The amd64 version of the packet has the version tag "5.9.5-2ubuntu2.1", all others are "5.9.5-2ubuntu2".
Thus the dependency is not found while installing libstrongswan-extra-plugins.
See following output while trying to install the package:

$ sudo apt install libstrongswan-extra-plugins

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created

The following information may help to resolve the situation:

The following packages have unmet dependencies:
 libstrongswan-extra-plugins : Depends: libstrongswan (= 5.9.5-2ubuntu2) but 5.9.5-2ubuntu2.1 is to be installed
E: Unable to correct problems, you have held broken packages.

Hello and thanks for this bug report. In Jammy by doing `apt show libstrongswan-extra-plugins` I see:

Depends: libstrongswan (= 5.9.5-2ubuntu2.1), ...

and looks like all the packages built from the strongswan source package have the correct versioned dependencies. Actually it would be quite hard to break them in they way you reported, so I think your local cache of available packages is corrupted or out of date (in a strange way).

Can you please run an `apt update` and check if the problem goes away? Thank you.

@paride
The failure did not go away with a apt update.
The official packet repository also highlights the problem:

https://packages.ubuntu.com/jammy/libstrongswan-extra-plugins

says it depends on libstrongswan, but

https://packages.ubuntu.com/jammy/libstrongswan

says it installs 5.9.5-2ubuntu2.1.
This is what my "apt show" command returns for both packages in question:

Hi, if you are able to reproduce the issue from a clean Ubuntu system please unexpire the bug and comment back providing steps we can follow. LXD containers are very useful in these cases. Thanks!
