I tried uninstalling, purging & re-installing sliver with no fix yet.

I also tried installing the one liner from your README.md , but still couldn't get it to work

@rkervella, i hope this answers the questions raised on issue #1361

@05t3 I think you have the Kali packaged version of Sliver installed as well as the official release. I suggest running apt remove sliver and sticking with the official releases since the version Kali has in its repos is old.

[rkervella]

@05t3 thanks for the details. Please try the following steps, and reopen the issue if that does not fix it:

• delete any sliver version you might have installed via apt (apt remove sliver)
• remove any sliver data from the system ($HOME/.sliver, /root/.sliver)
• install the latest release from this page
