hello all.
update: we tried both flatpak and snapcraft builds but we were facing issues related to our use of Qt, among other things.
after spending months on this project, we have decided to shelf it for now so we can put more resources on bug fixing and reliability.
we will revisit in the future, perhaps with appimage.
insync works on both debian (ubuntu, etc.) and fedora (redhat, etc.) based distros so if you are having issues with installing/running insync on them, please email support@insynchq.com.
thanks!
