What is the best way to install & upgrade Cassandra on Ubuntu ?
How do you install Cassandra on Ubuntu & later how do you upgrade the
installation on the node when an update has arrived ? Do you simply
download & replace the latest tar.gz, untar it to replace the older
cassandra files? How do you do it ? How does this upgrade process differ
for a major version upgrade, like say switching from 1.2 series to 2.0
series ?

Probably due to licence concerns.

Thanks for clarifications!
Btw DSC installs OpenJDK when java is not present on your system. Don't
know why it doesn't include just the preferred Oracle JRE installation &
take care of later updates to that as well, so that could be a reason to
choose DSC over official apache Debian(as that would be complete package to
run cassandra), otherwise I can't see any strong reasons to prefer it !?

Opscenter is a separate package:

Thanks Aaron!
Does DSC include other things like Opscenter by default ? I installed DSC
on linux, but Opscenter wasn't installed there but when tried on Windows it
was installed along with JRE & python, using the windows installer.
Would it be possible to remove any of these installations but keeping the
data intact & easily switch to the another, I mean switching from DSC
package to apache one or vice versa ?

They are technically the same.
The DSC update will come out a little after the Apache release, and I _think_ they release for every Apache release.

I am not sure if I should use datastax's DSC or official Debian packages

Could you please clarify that:
1. when I upgrade to a newer version, would that retain my previous
configurations so that I don't need to configure everything again ?
2. would that smoothly replace the previous installation by itself ?
3. what's the way (kindly, if you can tell the command) to upgrade ?
4. when should I prefer datastax's dsc to that ? (I need to install for

Use the deb packages. To upgrade, install the new package. Only upgrade a
single major version. and be sure to consult NEWS.txt for any upgrade
caveats.
Also be aware of this sub-optimal behavior of the debian packages :
