Hello,
thank you all for testing this and reporting here! This made the task a lot easier for me.
After performing the steps mentioned HERE the upgrade went through smoothly, besides 20-minute wait and fear without output in the updater.log because of this BUG, which is still not resolved.
Still, the App Center offers upgrades for “Kopano WebApp” to version 3.4.19.1649 and “Z-Push for Kopano” to version 2.4.2 because the actual version numbers are not transferred for the Kopano Repo installed products.
Is there something I should/could do about this?
BR,
TP
