My company uses an HTTP proxy and our various Ubuntu 12.04 servers therefore need to be configured properly, namely by setting etcaptapt.conf.d80proxy
to:
Acquire::http::Proxy "http://proxy.mycompany.com:80";
Acquire::http::No-Cache true;
Now, since a few days, this method suddenly stopped working: I run into sum mismatch errors. I have tried all the usual tricks found on stackoverflow or on the web, among others:
sudo rm -fR /var/lib/apt/lists/*
sudo apt-get clean
But nothing seems to work. I even switched to a FTP server, without any luck. What's a radical solution to this problem? Is it likely that the proxy server has some kind of issue? What could it be?
