mint linux DNS lookup failed!
Bitmask used to work fine on linux mint, after I did clean install to the latest release Mint 18.3 bitmask not working the same as before I always get this error message with different providers (The server at riseup.net can't be found, because the DNS lookup failed. DNS is the network service that translates a website's name to its Internet address. Either your computer is having trouble connecting to the network, or you are missing some helper files that are needed to securely use DNS while Encrypted Internet is active. To install these helper files, quit this application and start it again.) even with different version of bitmask (0.10.1 - 0.10.2 - 0.9.2), how I can solve this problem?
