Hello

I installed Ububtu 11.04 headless on a PandaBoard. I'm using minicom.

I'm trying install ROS on a Pandaboard through minicom. I follow the web:

and the guide indicate:

I introduce the first comand by minicom:

sudo apt-get install build-essential python-yaml cmake subversion wget python-setuptools mercurial

and I received the next text in the minicom:

make subversion wget python-setuptools mercurialll build-essential python-yaml c 
Reading package lists... Done
Building dependency tree       
Reading state information... Done
Package mercurial is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source

E: Package 'mercurial' has no installation candidate

Can you help me please? how can I install ROS?

Thanks so much

Regards

hi!!

Yes, it's strange. I did copy-paste of the comand, then I think that no had error write.

I don't understand good the "ports.ubuntu.com and universe turned on", I'm new with ROS and I only know a bit Linux SO, but I think that one of the steps that I followed in the guide was apt-get update.

I eliminated the word mercurial of the comand and the instalation was successfull. I'm not sure that it are good or correct and the ROS will run correctly.... :S. I can create new packages, directories,... I will try to work...

Thanks so much.

Check the file: /etc/apt/sources.list. There will probably be some commented lines starting with deb and ending with univserse. If you uncomment those and rerun apt-get update you enabled the universe repositories. Additional packages as mercurial will be available.

Try "sudo apt-get install mercurial" by itself. Your results look strange. It looks like you thought you typed mercurial but entered mercurialll instead. Did you correct it in some places when you posted your message?

Make sure you have ports.ubuntu.com and universe turned on in your apt sources. And make sure that you apt-get update before you try the install.

I find what looks like healthy packages in the repo.

Adding to what Tully said, a good way to turn on the universe and multiverse in you apt sources from command line is described here.

After you apt-get update you should be able to locate and install mercurial.
