I terminated a running instance of 1.5.5, and tried to install 1.5.7 (re-downloaded from link above) with sudo dnf install. At the end, both 1.5.5 and 1.5.7 were installed:
> sudo dnf install ./insync-1.5.7.37371-fc26.x86_64.rpm

I removed both of them, and reinstalled 1.5.7, and started it manually. Now it seems to be working just fine. I will keep using and report back here any problems.
The RPM upgrade through dnf still needs to be fixed to avoid simultaneous versions, and the installation script also has some issues (xmessage is not installed – maybe gxmessage should be listed as a dependency? – and some key import seems fo fail). But, aside from that, insync seems to be running just fine once again. Thanks for the update!
