Visual Studio Code Marketplace in Ubuntu: ERR_PROXY_CONNECTION

When I try to search the name of a given extension in Visual Studio Code on my Ubuntu 22.04.1 LTS, I get the following error message: Error: while fetching extensions, XHR failed. When I toggle to the developper tools I find this: ERR_PROXY_CONNECTION_FAILED

My proxy settings were specified using the Settings GUI that comes with Ubuntu, in a .conf file inside /etc/apt/apt.conf.d, in the environment file inside /etc, and against vscode using the command code --proxy-server=http://ip:port. I also tried to set the proxy settings for chrome using google-chrome --proxy-server=http://ip:port but then I get the following error message:

libva error: vaGetDriverNameByIndex() failed with unknown libva error, driver_name = (null)

I also run the following commands for proxy setings:

gsettings set org.gnome.system.proxy mode 'manual'

gsettings set org.gnome.system.proxy.http host 'ip'

gsettings set org.gnome.system.proxy.http port prt

(Obviously, ip and prt denote the real values that I used)

CodePudding user response：

I managed to solve this by adding the following lines in home/user/.config/Code/User/settings.json:

    "http.proxy": "http://ip:port",
    "https.proxy": "https://ip:port",
