Connecting to my company web site from my Ubuntu machine I had some rendering problem because the requested font (trebuc) was not installed. I try to reinstall the package ttf-mscorefont-installer with the error “[Errno 113] No route to host”
Running the command:
sudo -i set|grep proxy
No proxy output was displayed.
So the solution was to update the file /etc/environment:
all_proxy=socks://192.168.1.2:3128/ ftp_proxy=http://192.168.1.2:3128/ http_proxy=http://192.168.1.2:3128/ https_proxy=http://192.168.1.2:3128/ no_proxy=localhost,127.0.0.0/8
and run this command to resume installation:
sudo -i /usr/lib/update-notifier/package-data-downloader
