3.4.0 dont show main dialog window in MATE


I have done search of this issue and I know there is a known bug, but unfortunally, there is no updates for Ubuntu 20.04 that would fix it. And I am not able to find any workaround for it and I need one, because muy users are using Ubuntu-mate and when they find any sync issue, we are not able to see them because the main dialog is not opening.

If anyone knows any workaround, it would be apreciated.

Thank you!

Hi, same for me. I am on Ubuntu 20.04.3. Version 3.4.2 of the Desktop sync client does not fix this but its a known issue: https://github.com/nextcloud/desktop/issues/4069
According to the Github issue you could install the AppImage from https://nextcloud.com/install/#install-clients as a workaround and this should fix it.
