 Upgrading from QGIS 3.18.8 to 3.18.9 using the network installer results
 in the following error during the installation procedure:

 {{{crssync.exe The program can't start because icuin56.dll is missing}}}

 This means that the qgis-ltr-common package fails to install correctly and
 QGIS fails to launch, with the following error:

 {{{Error loading QGIS - could not load qgis_app.dll. The specified module
 could not be found.}}}
