How to Install Vagrant on Ubuntu 22/24
Vagrant enables the creation and configuration of lightweight, reproducible, and portable development environments.
Follow these steps to install the latest version of Vagrant on Ubuntu.
Step 1: Add the HashiCorp Repository
To add the HashiCorp repository, run the following commands:
wget -O- https://apt.releases.hashicorp.com/gpg | sudo gpg --dearmor -o /usr/share/keyrings/hashicorp-archive-keyring.gpg
echo "deb [signed-by=/usr/share/keyrings/hashicorp-archive-keyring.gpg] https://apt.releases.hashicorp.com $(lsb_release -cs) main" | sudo tee /etc/apt/sources.list.d/hashicorp.list
sudo apt update
Step 2: Install Vagrant
sudo apt install vagrant -y
Step 3: Verify the Installation
To confirm that Vagrant was installed successfully, check the version:
vagrant --version
Step 4: Install VirtualBox (optional)
Vagrant requires a provider, such as VirtualBox, to run virtual machines. Install VirtualBox with this command:
sudo apt install -y virtualbox
Use: Create a Development Environment with Vagrant
To create a Vagrant project, start by creating a new project directory in your preferred location for Vagrant
configuration and related files.
mkdir vagrant-project
cd vagrant-project
To initialize the Vagrant configuration file with an Ubuntu box, run the command:
vagrant init ubuntu/jammy64
You can add the --minimal flag to the initialization command of the Vagrantfile to generate a Vagrantfile without
any additional settings.
Manage Vagrant
1.vagrant up: Launches the virtual machine and provisions it according to the settings in the Vagrantfile. This
command will simply connect to the virtual machine if it is already running.
2.vagrant halt: Stops the virtual machine by delivering a shutdown signal to the guest operating system. This
command is similar to shutting down a real computer.
3.vagrant reload: Restarts the virtual machine and re-provisions it depending on any changes in the Vagrantfile.
4.vagrant ssh: Connects to the virtual machine via SSH. This command is useful for accessing the command line
interface of the virtual machine.
5.vagrant status: Shows the current status of the virtual machine, including whether it's running, stopped, or
suspended.
6.vagrant destroy: Deletes the virtual machine and all associated resources. This command is useful for cleaning up
your development environment.
BONUS CHEATSHEET:
Some common SSH troubleshooting:
1. The default username and password for Vagrant's SSH access are often both set to vagrant. If you're prompted
for a password, try entering vagrant.
2.Use SSH Keys: Most Vagrant boxes use SSH key-based authentication, not passwords. Vagrant automatically sets up a
private key (.vagrant/machines/default/virtualbox/private_key by default). You can try connecting with this key
manually:
ssh -i .vagrant/machines/default/virtualbox/private_key vagrant@127.0.0.1 -p 2222
3. Re-provision the VM: If the configuration seems incorrect, run:
vagrant reload --provision
4.Force a Specific Key Type: You can try forcing the use of RSA, as some SSH clients default to newer key types not
supported by certain Vagrant boxes. Use this command:
ssh -o HostKeyAlgorithms=+ssh-rsa -o PubkeyAcceptedKeyTypes=+ssh-rsa -i .vagrant/machines/default/virtualbox/private_key vagrant@127.0.0.1 -p 2222
5.Regenerate SSH Key: Sometimes, the private key in .vagrant/machines/default/virtualbox/private_key can become
corrupted or incompatible. You can try destroying and recreating the VM to regenerate a fresh SSH key:
vagrant destroy -f
vagrant up
6.Vagrant Box Compatibility: Some older Vagrant boxes may not support recent SSH configurations. If you’re using an
old box version, consider updating it:
vagrant box update
vagrant destroy -f
vagrant up
