Okay, open a terminal and run these commands: or cd into the unzipped directory and then run sudo openvpn --config "TunnelBear Germany.ovpn":
wget https://s3.amazonaws.com/tunnelbear/linux/openvpn.zip
unzip openvpn.zip
cd openvpn
sudo openvpn --config "TunnelBear Germany.ovpn"
Enter your password for sudo, then vpn username and vpn password. Keep the terminal open and do not close it until you are ready to stop the VPN; closing the terminal closes the VPN session. Also, the terminal will output realtime status and error messages so you can keep tabs on the tunnel status.
I guess you have to run the command from the directory that contains all the files (cert key etc), otherwise the config file won't know where to find them. That is not typical of openvpn client files but they all (different vpn providers) seem to have their own (slight) unique differences.
These commands replace the "tb-downloader.sh" script from github in case you tried using that as the original script fails to rename the files as country.ovpn.
wget https://s3.amazonaws.com/tunnelbear/linux/openvpn.zip; unzip openvpn.zip
mv openvpn tunnelbear.d; cd tunnelbear.d
for f in *.ovpn; do mv "$f" `echo $f | sed 's/ //g;s/TunnelBear//g'`; done
cd ..; chmod 600 tunnelbear.d/*; sudo chown root:root tunnelbear.d/*
