can't install on Deepin OS (based on Debian/Ubuntu)

Recommended Posts


+ I had synergy 1.11.1 on Deepin OS 

+ I uninstalled it to install the newer version

+ I can't install the new  version

I use this procedure:

1) sudo dpkg -i synergy_1.12.0.stable_b20200827.1+cb8064e8_ubuntu20_amd64.deb

2) sudo apt -f install

please note that my OS needs certain Qt modules, while Synergy wants newer modules. I think (part of?) the problem is that the OS doesn't work with newer modules.

if I use above method to install some newer Qt modules (from .deb file), I get the above message in post 2 which messes up the system
