What is going on here? Thanks!

推荐答案

主存储库中似乎确实缺少 gcc-4.9.4，它只有 gcc-4.9.3:http://us.archive.ubuntu.com/ubuntu/pool/universe/g/gcc-4.9

It seems that gcc-4.9.4 is indeed missing from the main repository, which has only gcc-4.9.3: http://us.archive.ubuntu.com/ubuntu/pool/universe/g/gcc-4.9

这解释了 apt 中的 404 Not Found 错误.
作为第一次修复尝试，您可以尝试以下操作，以防出现apt 能够修复的冲突:

This explains the 404 Not Found error from apt.
As a first fix attempt, you may try the following, just in case there's a conflict which apt will be able to repair:

sudo apt-get update --fix-missing
sudo apt-get dist-upgrade
sudo apt-get install gcc-4.9 g++-4.9 gcc-4.9-multilib

Ubuntu 16.04

在 Ubuntu 16.04 上，可以从 Launchpad 工具链存储库安装 gcc-4.9:

On Ubuntu 16.04, gcc-4.9 could be installed from the Launchpad Toolchain repository:

sudo apt-add-repository -yu 'deb http://ppa.launchpad.net/ubuntu-toolchain-r/test/ubuntu xenial main'
sudo apt update
sudo apt-get install gcc-4.9 g++-4.9 gcc-4.9-multilib

Ubuntu 18.04(可能还有 17.10、17.04)

Ubuntu 18.04 (and probably 17.10, 17.04)

如果上述方法不起作用，您可以手动安装 gcc-4.9 以及所有必需的依赖项，方法是使用 dpkg 获取所需的软件包并按顺序安装它们:

If the above didn't work, you could go about installing gcc-4.9 manually along with all required dependencies, by grabbing the required packages and installing them by order, using dpkg:

mkdir ~/Downloads/gcc-4.9-deb && cd ~/Downloads/gcc-4.9-deb

wget http://launchpadlibrarian.net/247707088/libmpfr4_3.1.4-1_amd64.deb
wget http://launchpadlibrarian.net/253728424/libasan1_4.9.3-13ubuntu2_amd64.deb
wget http://launchpadlibrarian.net/253728426/libgcc-4.9-dev_4.9.3-13ubuntu2_amd64.deb
wget http://launchpadlibrarian.net/253728314/gcc-4.9-base_4.9.3-13ubuntu2_amd64.deb
wget http://launchpadlibrarian.net/253728399/cpp-4.9_4.9.3-13ubuntu2_amd64.deb
wget http://launchpadlibrarian.net/253728404/gcc-4.9_4.9.3-13ubuntu2_amd64.deb
wget http://launchpadlibrarian.net/253728432/libstdc++-4.9-dev_4.9.3-13ubuntu2_amd64.deb
wget http://launchpadlibrarian.net/253728401/g++-4.9_4.9.3-13ubuntu2_amd64.deb

sudo dpkg -i gcc-4.9-base_4.9.3-13ubuntu2_amd64.deb
sudo dpkg -i libmpfr4_3.1.4-1_amd64.deb
sudo dpkg -i libasan1_4.9.3-13ubuntu2_amd64.deb
sudo dpkg -i libgcc-4.9-dev_4.9.3-13ubuntu2_amd64.deb
sudo dpkg -i cpp-4.9_4.9.3-13ubuntu2_amd64.deb
sudo dpkg -i gcc-4.9_4.9.3-13ubuntu2_amd64.deb
sudo dpkg -i libstdc++-4.9-dev_4.9.3-13ubuntu2_amd64.deb
sudo dpkg -i g++-4.9_4.9.3-13ubuntu2_amd64.deb

以上是在 18.04 上测试的，并产生了一个功能性安装的 gcc-4.9.

The above was tested on 18.04 and produced a functional installed gcc-4.9.
