Answer 1

Not sure why, but the EPEL repo is installed, but disabled by default. You can enable it permanently by changing the setting "enabled=1" in the [epel] stanza of /etc/yum.repos.d/epel.repo

Or you can leave it disabled and still install byobu:

sudo yum install --enablerepo=epel byobu

You can have a look at what packages are available in the epel repo with:

sudo yum list --disablerepo=\* --enablerepo=epel

Answer 2

For Amazon Linux 2:

You would need to install the EPEL release package for EL7 based AMI and enable the EPEL repository.

You may execute below: ⤵︎

sudo amazon-linux-extras install epel      # Install epel from Amazon's Linux Extras

sudo yum-config-manager --enable epel      # Enable EPEL repo in case disabled

sudo yum install byobu -y                  # Install byobu

byobu -v                                   # Verify Version

Here is the alternative source just in case Linux Extras don't work for you.

# (optional) Install EPEL repository from Fedora
sudo yum install -y https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm

Answer 3

The error message indicates that the package byobu is not available in the amzn-main repository.

You can manually install it from another repository

cd ~
wget ftp://ftp.pbone.net/mirror/download.fedora.redhat.com/pub/fedora/epel/5/x86_64/byobu-3.4-2.el5.noarch.rpm    
sudo yum install byobu-3.4-2.el5.noarch.rpm
