apt in Linux Subsystem for Windows 10 is failing with 404 Not Found
For what it's worth: I landed on this SO topic after having a similar issue.
What fixed it for me was to run
sudo apt-get updatesudo apt-get upgradeI guess the repo URLs were too old, even though my Ubuntu was in a recent version.
I just ran into the same thing attempting to install python-pip. According to this article, this happens when you have the Windows 10 Anniversary Update (older) instead of the Creators update (newer). The solution is to either uninstall and re-install Ubuntu, or upgrade it (from 14.04 to 16.04). I found the upgrade to be simple and painless:
sudo do-release-upgrade
To check what you have, before and after via:
lsb_release -a
I had the same problem. Pinging the IP resulted in no response and visiting the website returned a 404.
I found a ppa with most current GCC and registered the PPA and was able to successfully install GCC with it; ppa website. I used GCC to build some software I wanted that was not found with apt-get.
From their page:
sudo add-apt-repository ppa:ubuntu-toolchain-r/testsudo apt-get update
