I have four build servers that were all setup the same originally. We've been using them to cross-compile C projects. I'm trying to update them compile C++ natively as well. Two of the servers I was able to install g++ on with no problem, the other two though gave me 404 errors.

I run into this issue almost every time I set up a new box.
Run sudo apt update before you install the packages.
If running from docker and you already have apt-get update in your Dockerfile try running with --no-cache or use cache busting.
Set your system time to the correct time of your time zone and then try sudo apt update before running your command sudo apt-get install g++
for me I solved the issue by fixing the time zone difference
- I correct the time zone
sudo apt cleansudo apt autocleansudo apt update
that works just fine.
In my case, changing the sources of ubuntu-esm-infra (located in /etc/apt/sources.list.d/ubuntu-esm-infra.list) from xenial to bionic resulted in 404 or 401 errors.
As packages of this source are not essential for running Ubuntu (mybe Canonical thinks differently), I deactivated these sources before do-release-upgrade.
after running the standard
apt-get update && apt-get upgrade no more errors showed up.
I have replaced source.list with below text, resolved my issue.
