unable to locate package alien

I have a jetson TX2.

I want to install the database oracle on ubuntu.

However, you need an alien to install the oracle rpm file.

sudo a-t-get update
sudo apt-get install alien

If you enter the above command, the following error message appears.

===========================================
Reading package lists… Done

E: Unable to locate package alien

Why? It is very positive.

It is there, you probably just need to enable the right repository:

root@x2:~# apt search alien
Sorting... Done
Full Text Search... Done
alien/xenial 8.95 all
  convert and install rpm and other packages
...

This is my “/etc/apt/sources.list” (if you edit be sure to run “sudo apt update” before looking for packages):

I do have doubts Oracle can run on this architecture. I’m very curious to find out if this works.

Thank you for answer.

But…
I have tried apt search as a guide but the following results are shown.

root@tegra-ubuntu:~# apt search alien

Be aware that if there are any changes to sources.list, then you need to run “sudo apt update” before the changes will take effect. In a similar way, you may need to run “sudo apt update” prior to seeing simple package updates. Have you run “sudo apt update” prior to the “search”?
