Solution for Box not found error in Vagrant

I was facing this error:

The box 'centos/7' could not be found or
could not be accessed in the remote catalog. If this is a private
box on HashiCorp's Atlas, please verify you're logged in via
`vagrant login`. Also, please double-check the name. The expanded
URL and error message are shown below:

URL: [""]
Error: The requested URL returned error: 404 Not Found

Adding this line in Vagrantfile helped:

Vagrant.configure("2") do |config|

multiple commits in a PR

I ended up with multiple commits in my PR after a rebase (and followup push) in my "working" branch.


I first copied those few files which I have modified/ added into a temp directory (along with entire path).

then reset my branch with origin/master.

git reset --hard origin/master

So, now the "working" branch is in sync with master branch.

Now, copy back all those files from temp directory into the "working" branch.

Carried out a fresh commit with all changes and verified all changes looks fine.

Then, just did a force push as :

git push --force

Now, you can check in github whether only one commit with required changes present.

Always verify git status before a push especially after a rebase.

PS: not an optimal solution, but manual way.

store vagrant boxes in custom directory

By default vagrant stores  boxes here at ~/.vagrant.d/boxes

Sometimes, we want to make use of custom location instead of above.
you can make use of VAGRANT_HOME directory.

export VAGRANT_HOME=/path/to/yourown/location

You can make it permanent by adding the above in your bashrc file.

ansible logging and debugging

If you pass the -v flag to ansible-playbook on the command line, you'll see the stdout and stderr for each task executed:

$ ansible-playbook -v playbook.yaml

You can also choose -vvv for more verbose output.

Check  for more options:
#ansible-playbook --help | less
Ansible also has built-in support for logging.
Add the following lines to your ansible configuration file(/etc/ansible/ansible.cfg):

Git aliases

edit ~/.gitconfig as below:

        fetch = fetch -v
co = checkout

You can do the same using command line too: (which will in turn update ~/.gitconfig file)

# git config --global checkout

You can list/verify same using the command

# git config --global -l
alias.fetch=fetch -v
