Post-Install Step Issue (3.6)

[Wicky2k8]

Installing QGIS 3.6 from the bottle works well, but the post-install step fails. This seems to be because the script is trying to copy files which are already symlinked to in the QGIS .app's pluging folder, but not 100% sure..

The installation still works, not sure if anything important in the post-install script is skipped. (In prior builds not all plugins were installed because of this, but that seems to have been fixed.)

Yes, it seems that the link was created when creating the bottle, it should not be like that, since they are indicated in postinstall.

In the next version I will have them generated before postinstall.

Do not worry about that warning, it should work fine.

or you can reinstall, uninstalling previously qgis-res and doing then:

brew install qgis

Thanks for the warning, I'll keep it in mind for the next release. We can close this issue.

Thank you!
