Recently I came accross the issue of wanting to install apt packages in WSL behind a corporate proxy. Plus I wanted to update my yarn package by using “curl -o- -L https://yarnpkg.com/install.sh | bash” which also needs to go through the proxy.
The solution is the same as if we want to set the proxy in a standard Ubuntu. So simply create a proxy.conf inside the apt config folder as follows.
vi /etc/apt/apt.conf.d/proxy.conf # add the following line (press i to insert and escape followed by :x to save) Acquire::http::Proxy "http://username:password@myproxy:myproxyport";
Aditionally we need to set the proxy for curl. For that we create or modify an user specific ~/.curlrc file in our homefolder.
cd ~/ vi .curlrc # insert the following line
proxy = <proxy_host>:<proxy_port>
Thats it. You are now using apt and curl through your corporate proxy.
