It seems 1.3.6 has problems with Linux, or at least with Debian.
I would recommend to go back to 1.3.5 until this is sorted.
I reckon you know how to do that, but just in case you don’t, it’s simple :
1°) open terminal and enter : “sudo apt-get remove --purge insync*”
2°) go to your “home”, show hidden files (that is Ctrl +H), find .config and delete the “insync” folder inside of that .config.
Then download the correct 1.3.5 version from this link :
And reinstall it.
Not sure you’ll be able to go back to where you were and maybe a new sync will be needed
@fedele.mantuano: Apologies for the trouble. There was an issue with the Debian builds for 1.3.6. Version 1.3.7 for Debian has been uploaded. The download links in New Insync version: 1.3.6 has been updated. The update has also been pushed to the Debian repos.
