This is on Ubuntu 14.04 (SERVER, so no GUI)

Ok so earlier today I was asked to upgrade GCC to GCC 4.9 (current available is GCC 4.8 for Trusty).

So following these directions I installed the PPA ubuntu-toolchain-r/test. Well, turned out we did not need GCC 4.9 and I wanted to revert back to 4.8. So I followed these instructions and I:

Used ppa-purge tool:

sudo ppa-purge ppa:ubuntu-toolchain-r/test

I removed the repository with --remove 

sudo apt-add-repository --remove ppa:ubuntu-toolchain-r/test

And manually removed the PPA file from /etc/apt/sources.list.d as well as the keyring.

But now, whenever I run

sudo apt-get upgrade

It's still asking me to upgrade GCC to 4.9 (and several other toolchain related packages.)

All of what you did is just right. But you miss to do one important thing.

sudo ppa-purge ppa:ubuntu-toolchain-r/test

sudo apt-add-repository --remove ppa:ubuntu-toolchain-r/test

And manually removed the PPA file from /etc/apt/sources.list.d as well as the keyring.

Now before doing 

sudo apt-get upgrade

you should make 

sudo apt-get update

then make 

sudo apt-get upgrade

Your problem is you are still working on the software list that containing that repository, so you have to do apt-get update to update this list without the ubuntu-toolchain-r/test repository.

The first command will only disable the PPA, not actually remove and install the original packages from Ubuntu repository:

sudo apt-add-repository --remove ppa:ubuntu-toolchain-r/test

So you'll need to enable the Repository one more time, go to Software Center > Edit menu > Sources, and run ppa-purge first.

sudo ppa-purge ppa:ubuntu-toolchain-r/test
