Now Atom is migrating completely to x64, but if we only have a 32 bit machine, some tweak must be done to install Atom.

0. Add repository

sudo add-apt-repository ppa:webupd8team/atom

If you see this error:

Cannot add PPA: 'ppa:~webupd8team/ubuntu/atom'.
ERROR: '~webupd8team' user or team does not exist.

There may be two reasons:
1. You are behind a proxy.
2. Your ca-certificate is broken.

1-1. Set proxy as system variable.

export http_proxy=http://PROXY:PORT
export https_proxy=http://PROXY:PORT

And, use sudo -E to make sudo to preserve/respect the variables you just set:

sudo -E add-apt-repostory ppa:webupd8team/atom/

1-2. Reinstall your ca certificates.

sudo apt-get install --reinstall ca-certificates

2. Refresh source list and install

sudo apt-get update
sudo apt-get install atom

And you are done!

Where is Atom installed? The question is not easy to answer. Check out /usr/bin/atom.sh and you may have a better understanding. In my case(Ubuntu 16.04 LTS 32 bit), it's in /opt/atom/atom.
