On my desktop machine, which has a static IP, I manually blew a hole through the ports that Teamviewer likes to use and as a result it will only work with that device on my network, but that certainly made the issue a negative. I installed that same package on my laptop which is running KDE, which had the same problem and rebooted TV and it got a connection, however this may not work for you. The solution to this is either to manually punch a hole for your computer through the ports on your router or firewall, or, there is another solution floating around which involves installing a package called libnss-resolver. Run the following command in order to download the key: cd /tmp wget. First, you need to download the TeamViewer repository key as we will install TeamViewer through its official website. Open the Terminal either through the system Dash or the Ctrl+Alt+T shortcut. If you look down to the bottom left of that image, sending information isn't going to work because there is no connection to the server. Step 1: Download and add the TeamViewer repository key. This results in the client not allowing input in any field which would end up sending information to their servers. For additional help or useful information, we recommend you check the official Ntopng website.The error comes because for some reason, which I cannot understand, on some builds of linux, Teamviewer doesn't get through your router, firewall or some other blocking device.
