The update could not be calculated

[Christian Martinez]

I tried to update Ubuntu server but this message appeared
The update could not be calculated
An unsolvable problem occurred while calculating the update.
This could be due to
*Unofficial software packages, not providad by Ubuntu
Use the <<ppa-purge>> tool from the package ppa-purge to remove foftware from a Launchpad PPA and please try to update again.
If none of this applies, then report this bug using the <<ubuntu-bug-release-upgrader-core>> command in a terminal. If you want to investigate the problem yourself, the logs in <</var/log/dist-upgrade>> contain details of the upgrade; in particular see <main.log>> and <<apt.log>>
In the main.log file this shows as the last message:
WARNING Can't mark 'ubuntu desktop' for upgrade (E:Could not fix problems, you have retained broken packages.)
In apt.log file shows in the last lines:
Broken ubuntu-desktop:amd64 Depende on gnome-shell-extension-ubuntu-tiling-assistant:amd64 < none @un mH >
  Considering gnome-shell-extension-ubuntu-tiling-assistant:amd64 1 as a solution to ubuntu-desktop:amd64 10001
