package seahorse 2.25.91-0ubuntu1 failed to install/upgrade:

[Kazagistar]

Binary package hint: seahorse

For a week now, my seahorse package has been broken, and every upgrade informs me that is has failed.
This causes the Ubuntu-Desktop package to also be broken.

Excerpt from apt-term.log:

Setting up seahorse (2.25.91-0ubuntu1) ...

Thanks for your report. Do you use any non-official repositories? I can't reproduce this issue here. Could you attach your /etc/apt/sources.list to this report? Thanks.

Could you please try out to completely purge seahorse, delete the downloaded package and reinstall seahorse?

Here is what happens when I try to purge it:

$ sudo dpkg -P seahorse

that's not a seahorse bug but a local installation issue
