Hello

I have recently installed DB2 express on UBUNTU and am not able to get
it to start. I decided to uninstall and reinstall DB2. When I enter the
command sudo ./db2_deinstall it says "No DB2 Packages found on this
system...." Please help me. I am new to DB2 on Unix.

Thanks

Could you be a bit more specific?
What does "no luck" mean? Do you get an error message?
What do you mean by "showed my the bunch of packages"?

Regarding your question how to see the packages, have you "rpm" installed?
If so, you can use it to see which DB2 packages are installed. You can
also use it to deinstall those packages. (man rpm)

In order to install on Ubuntu, you had to modify the db2_install script. To
deinstall, you're going to have to modify the db2_deinstall script in a
similar manner. You'll have to change the "rpm" commands to the
appropriate "alien" command, and then run it.

Good luck - perhaps if no one here knows how, you can use that information
to get people in a Ubuntu newsgroup (or web forum) to help.

You need alien installed. Since Ubuntu is debian based and does not use
rpms natively. Then you need to modify the db2_install script to make
it use alien instead of rpm.

When you installed using db2_install for the first time, did you modify
the scripts? If not, then probably nothing has been installed. Thats
why it says, No DB2 packages found...

The easiest way to install alien is to use the Synaptic package
manager. Search for alien and mark for install and apply changes. If
you dont see alien (as it may not be a Ubuntu supported package), you
have to go to the options and add Universal sources.

Now, I believe you did all this with DB2 8.x. Download DB2 Express-C v9
and it will install like a breeze with graphical support out of the
box.

Let us know if you have any more trouble. Check this TLDP guide for a
step by step procedure on installing DB2 on Ubuntu (command line).
