    <p>Hi,</p>
    <p>Can you please tell us which repositories are you using? Check
      "apt policy" for qgis/postgis related packages. The very first
      http address on the output is the repository you are using.</p>
    <p>Try something like:</p>
    <p>apt policy postgresql</p>
    <p>apt policy postgresql-10-postgis-2.5</p>
    <p>apt policy qgis</p>
    <p>Maybe you are mixing repositories.</p>
    <p>Regards,</p>
    <p>Jorge<br>
