Missing installation files

[Techtonictools]

Hello, I'm test driving and learning how to use opensnitch. I had ver 1.4.0.rc-1 installed and was having a problem and wanted to upgrade to the latest. I followed the uninstall instructions then did the install of 1.4.0.rc2. The UI launches but it doesn't connect with the service.

Ok, it seems that removing the directory /etc/opensnitchd by hand breaks the apt somehow.

Type this: apt remove --purge opensnitch; dpkg -i opensnitch_1.4.0.rc2-1_amd64.deb

I'll update the wiki to clarify the uninstallation steps. Edit: wiki updated to clarify uninstallation steps, added upgrade steps.

That solved the problem. Thank you.
