Vagrant can't run.

[hack3rcon]

Hello.
I installed "VirtualBox 6.0_6.0.4" and "Vagrant" on Debian 9.8 but when I want to run Vagrant then it show me below error:

Code: Select all

$ vagrant up
No usable default provider could be found for your system.

Vagrant relies on interactions with 3rd party systems, known as
"providers", to provide Vagrant with resources to run development
environments. Examples are VirtualBox, VMware, Hyper-V.

The easiest solution to this message is to install VirtualBox, which
is available for free on all major platforms.

If you believe you already have a provider available, make sure it
is properly installed and configured. You can see more details about
why a particular provider isn't working by forcing usage with
`vagrant up --provider=PROVIDER`, which should give you a more specific
error message for that particular provider.

And "VirtualBox" show me below error:

Code: Select all

$ virtualbox
Qt FATAL: QXcbConnection: Could not connect to display 
Aborted

How can I solve it?

Thank you.

I installed "VirtualBox 6.0_6.0.4" [...] on Debian 9.8

How? That package was removed from Debian stable (because it's crap).

For vagrant try following the advice that you posted:

Code: Select all

vagrant up --provider=virtualbox

Why, It is crap?
I installed the last version of Vagrant and problem solved.

The package was removed from the stable release because Oracle like to hide VirtualBox bugs from their users:

https://bugs.debian.org/cgi-bin/bugrepo ... bug=794466

The VB devs usually can't be bothered fixing the bugs anyway, which should give you some idea as to the quality of the software.

But don't take my word for it, the kernel developers also share this opinion:

The number of bug reports we get from people with virtualbox loaded are truly astonishing. It's GPL, but sadly that doesn't mean it's good.

I installed the last version of Vagrant

And again the question would be: how did you do this?

You have read the first link in my signature, right?

I downloaded the .deb package from Vagrant website and installed it manually.
What is a replacement for Vagrant?
Is it true that VirtualBox based on KVM?

Thanks.

Ask the interweb, I don't even know what Vagrant is.

Is it true that VirtualBox based on KVM?

No.

KVM is a Linux kernel module that allows for hardware-based virtualisation and is best used with QEMU.

It is true that VirtualBox can make use of the KVM module but their implementation is as crap as the rest of their software and less effective than QEMU.
