Qgis: crssync.exe - System Error

[Saijin-Naib]

Describe the bug

After using OSGeo4W to upgrade my 3.12 install to 3.14

How to Reproduce
Use OSGeo4W to upgrade using Advanced and default selections.

QGIS and OS versions
Broken 3.14
Additional context

Website indicates that 3.14 is still in packaging and not released, so I guess what is occurring is OSGeo4W is applying a partial update and breaking the install.

@Saijin-Naib I think the issue is due to the protobuf library missing among the qgis package dependencies:

The same problem occurs with the standalone installer for 3.14 available at https://qgis.org/downloads/?C=M;O=D

If you manually install the protobuf library package using the OSGeo4W setup, then QGIS starts without problem.

I've filed a bug report on osgeo4w issue tracker: https://trac.osgeo.org/osgeo4w/ticket/634

@Saijin-Naib the bug was instantly fixed by @jef-n . The protobuf library was added as dependency of the qgis-common package.

It is now possible to correctly install QGIS 3.14 via the OSGeo4W network installer.

The standalone installer was removed from the download server, waiting for a new fixed version to be uploaded.

Thanks so much to you both!
