    <p>Hi César,</p>
    <p>this is the lesson I had to learn hard a dozend of times over the
      years: Do not update any ububuntugis related packages "after" a
      QGIS version update.</p>
    <p>Those two parts of the eco-system never managed to get in sync,
      and maybe never will (no idea how and why and what, I'm just a
      user).<br>
    </p>
    <p>On Linux Mint, I recently discovered in the Update manager the
      possibility to right-click on a package name, and set it to be
      ignored for updates.</p>
    <p>And fortunately, a hover-over the package name reveals the
      source, so I can deactivate all ubuntugis packages for updates
      within seconds.</p>
    <p>Hope this helps ... next time</p>
    <p>Cheers,</p>
    <p>Bernd<br>
