I have found Linux Mint to be problematic if your server uses proxy settings to get online. Ubuntu also require changes to the network settings if you use a proxy, but this only involves a simple change in the Network Settings panel. This doesn't work in Linux Mint, the settings can be entered but will not remain saved.
- Use a terminal to open
/etc/environment using a text editor as superuser. E.g. sudo gedit /etc/environment. - Add the following lines to the text document that appears, replacing myproxy.server.com with your proxy address.
http_proxy=http://myproxy.server.com:8080/
https_proxy=http://myproxy.server.com:8080/
ftp_proxy=http://myproxy.server.com:8080/
no_proxy="localhost,127.0.0.1,localaddress,.localdomain.com"
HTTP_PROXY=http://myproxy.server.com:8080/
HTTPS_PROXY=http://myproxy.server.com:8080/
FTP_PROXY=http://myproxy.server.com:8080/
NO_PROXY="localhost,127.0.0.1,localaddress,.localdomain.com"
- Save the file, then navigate to
/etc/apt/apt.conf.d/and create a new file there named 95proxies and include the following code (remembering to add your own proxy address in place of myproxy.server.com)
Acquire::http::proxy "http://myproxy.server.com:8080/";
Acquire::ftp::proxy "ftp://myproxy.server.com:8080/";
Acquire::https::proxy "https://myproxy.server.com:8080/";
Reboot and once you have logged in you will find that your proxy settings are in place for Network Settings, apt-get and Update manager. It's a pain but it does give you an idea about using the command line in a Linux terminal.
