===Ubuntu and Debian===
To install OSCAR on Ubuntu or Debian, download the appropriate file [https://www.sleepfiles.com/OSCAR/ from the official OSCAR web site] for your platform. Then:
<pre>sudo dpkg -i [OSCAR package filename.deb]</pre>
Substitute the name of the package you downloaded. It is important to use sudo rather than install as root, so that the package will install the .desktop file in your account.
To remove OSCAR:
<pre>sudo dpkg -r oscar</pre>
===Fedora, CentOS and Redhat===
