Trouble using Vagrant

Hi,
I’m making re-lecture of previous chapters, trying to rerun some vagrant VM given in the handouts.
So I decided to create new directories (~/university/m312/m312-vagrant-env-chp[1-4] )and unzip inside the archive “m312-vagrant-env.zip” given in every chapter.

Then I realized that I cannot have several instance of the same “m312” vagrant VM, so I did this :
vagrant destroy m312

Then I tried a “vagrant up” command line, but here is the error message I got :
ThinkPad-T420:~/university/m312/m312-vagrant-env_chp3$ vagrant up
Bringing machine ‘m312’ up with ‘virtualbox’ provider…
==> m312: Importing base box ‘ubuntu/trusty64’…
==> m312: Matching MAC address for NAT networking…
A VirtualBox machine with the name ‘m312’ already exists.
Please use another name or delete the machine with the existing
name, and try again.

Any idea how to reinstall a box m312 ? I’m actually stuck… :frowning:
Thanks,
Patrick

Go to your Oracle VirtualBox console and delete the VirtualBox named ‘m312’. I’d recommend using the “Delete All Files” option. Then start again. Good luck.

Thanks, it did the job!
