[SOLVED] How can I install Virtual Box?

[acer-manjaro]

Does this command now work, then?

Code: Select all

apt-get install virtualbox virtualbox-qt -t jessie-backports

Code: Select all

root@debian:/home/acer-manjaro# apt-get install virtualbox virtualbox-qt -t jessie-backports

You might want to run 'apt-get -f install' to correct these:

E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).

And I think the Oracle Virtual Box in partially installed because a logo appears in the Application menu. But when I open It, It doesn't open.
Maybe I should uninstall all Virtual Box files first and then Install it again.

What do you reckon?

Like I said, did you do as it suggested? Look at the error. It suggests to run:

Code: Select all

apt-get -f install

Just to summarize, Which all should I run ? there a a lot.

Code:
dpkg -i virtualbox.deb

Code:
apt-get -f install


Are these enough ?

Hi, as an alternative way to install virtualbox (Oracle version) you can download the .deb file from virtualbox.org and install it using package "gdebi" from Debian repos.

[phenest]

and install it using package "gdebi" from Debian repos.

How is the OP going to install gdebi if they can't install virtualbox using apt-get?

[stevepusser]

Because gdebi is in the main Debian repository and doesn't conflict with anything else.

To clear things up, the OP first tried to install the deb directly downloaded from Oracle, but used dpkg -i, which ended up resulting in missing dependencies. To finish up on that path---all that needs to finish the install is the command "apt-get -f install"--or to use gdebi to install standalone deb files instead of "dpkg -i".

However, it wasn't clear to me that the OP had an incomplete Oracle install, and I suggested installing the fairly recent version from jessie-backports. The Oracle and Debian versions conflict, so the incomplete Oracle install clogged up the works.

So the OP must decide whether to go with the Oracle version and finish its install, or to remove it and go with the jessie-backports version. Both are good choices, IMO. Just be aware that the jessie-backports version will always be at 5.1.8 and not get any possible security updates. If that depresses people, I could update my virtualbox jessie-backports repo in the openSUSE Build Service to the latest in upstream Debian--just ask here.

I think you misunderstood me Steve. If the OP is struggling with something as fundamental as this, there's not much hope for them installing anything else. And, to be honest, I'd rather teach something simpler, which so far has not advanced very much since the first post. The OP is trying to install software as one would in Windows. How many times have I installed a program in Windows just for it complain that a specific version of .Net is required but .Net needs to be downloaded separately. It would be nice if it grabbed it automatically, the same way it's done in a Linux distro packaging system.

Back to apt-get ...

Yup, I don't know if you have noticed, but we seem to have a few of these threads in the last couple days...ones where we have to spell out specifically how to get root or sudo, edit a simple text file, install a deb file or use a repo, and so on. It's difficult to know just how far down our basic instructions have to drop.

It seems some do not even know what a command line is, nor a terminal.

and install it using package "gdebi" from Debian repos.

How is the OP going to install gdebi if they can't install virtualbox using apt-get?

This is to confusing, but wouldn't

Code: Select all

apt-get install gdebi

install "gdebi' ? It should , the OP should read some documentation,.

The OP does not understand, or know how to install a package.

The OP does not know to use logic, they need every little detail spelled out,
No :

Code: Select all

apt-get -f install

is not enough, the command needs to also have the package name,.. for example:

Code: Select all

apt-get install -f virtualbox

or

Code: Select all

apt-get install gdebi

where it says "gedbi" or virtualbox, could be any package name,...but you must tell it the name of the package.
Read some documentation, read the manual:

Code: Select all

man apt-get

or if you prefer use "synaptic package manager"

Code: Select all

man synaptic

I don't know whether to continue being patient (by that I mean: putting a bandage on my head 'cos it's hit a wall so many times) and hope they "get it", or tell them they aren't suited to Debian (or Linux in general).

@ acer-manjaro: Don't read anything into my comment to stevepusser. It's not personal. We're all willing to help, but you need to "get it".

Perhaps we to start by removing everything thus far related to VirtualBox, and start again.

[phenest]

This is to confusing, but wouldn't

Code: Select all

apt-get install gdebi

install "gdebi' ?

You mean in the same way that:

Code: Select all

apt-get install virtualbox

would install VirtualBox?

You'd think wouldn't you. But let's start with VirtualBox as per thread title.

conclusion
The issue was my lack of knowledge and understanding of Debian & Linux in general.

Thank You, All

[GarryRicketson]

Your welcome, and congratulations,....

It takes some time to learn about linux, and Debian, but the more you practice, and also
read, the easier it gets. However it is a never ending process, we all keep learning new
things.

[stevepusser]

I still remember thrashing around trying to get Broadcom wi-fi working on my first Linux install in 2006, so don't think you're alone. We all have to start somewhere.

Over on MX Linux, several of our developers have written a very nice, start from the basics user manual that's included with the ISO--so now we can bang our heads on the wall whenever a new user asks us a question that's answered on the first page of the manual.

[phenest]

Yes, we've all been there. And once you "get it", you'll want to do more. It's almost infectious.
