The insync-thunar plugin for insync (v3) is not compatible with Linux Mint 19.2 or any other recent Linux distributions with XFCE desktop environment.
During the installation of insync-thunar debian (deb) package is always reported dependency error, that thunarx-python dependency is not available or satisfied.
Please, Insync dev team, fix this problem as soon as possible, because I need the fully functional Insync for Linux(XFCE) desperately.
Moreover, the insync-thunar plugin is not available at any insync repos, espacially at:
deb http://apt.insync.io/mint tina non-free contrib
I contact Insync support team two days ago, but so far without any relevant response regarding this terrible problem.
