I use Dell OMSA to manage iDrac, and to be able to do that, I need to install it on my Ubuntu 16.04 laptop.

The instructions on the Dell OpenManage page doesn’t specify the correct key servers, so please use the following commands instead to add the correct key:

sudo gpg --keyserver hkps.pool.sks-keyservers.net --recv-key 1285491434D8786F
sudo gpg -a --export 1285491434D8786F | sudo apt-key add -

Now add the repo:

sudo echo 'deb http://linux.dell.com/repo/community/ubuntu xenial openmanage' | sudo tee -a /etc/apt/sources.list.d/linux.dell.com.sources.list

Finally, refresh your packages and install the base package (without the web server):

sudo apt update
sudo apt install srvadmin-base srvadmin-idracadm7

If you want more than just the base package, pick any of the following:

Enjoy!
