Virtual Box 6 Installation Failure on Ubuntu 18.10

[planetrocker]

virtualbox-6.0 : Depends: libqt5opengl5 (>= 5.0.2) but it is not installable
                  Recommends: libsdl-ttf2.0-0 but it is not installable

i cannot locate and install packages libqt5opengl5 and libsdl-ttf2.0-0
in order to have virtualbox-6.0 working

I suggest using Oracle's repository for VB. Follow the instructions for "Debian-based" distributions at https://www.virtualbox.org/wiki/Linux_Downloads

[planetrocker]

i have already added it !

so we are missing 1 or 2 packages which need to be installed

[SeijiSensei]

I just installed VB from the Oracle repository. It brought in libsdl-ttf as well. I also have /usr/share/lintian/overrides/libqt5opengl5.

Now, I'm running Kubuntu which is built on the Qt platform, so I don't know if that library comes with vanilla Ubuntu.

For the record, I'm using 19.04, with the VirtualBox package for bionic (18.04). My apt entry reads:

deb [arch=amd64] https://download.virtualbox.org/virtualbox/debian bionic contrib

[planetrocker]

I updated

/etc/apt/sources.list

and tried to reinstall

still stuck on these packages

still stuck on these packages

Hello
I do not have this problem either, but I run 18.04

Is it available? In terminal:

apt-cache libqt5opengl5

Also try:

sudo apt install libqt5opengl5

That may give details as to why it will not install.

[planetrocker]

i get the message

Package libqt5opengl5 is not available, but is referred to by another package.

This may mean that the package is missing, has been obsoleted, or
is only available from another source

[cruzer001]

sudo apt update libqt5opengl5

If it will not update please post your sources

cat /etc/apt/sources.list && ls /etc/apt/sources.list.d/*.list

[cruzer001]

The package exist

https://packages.ubuntu.com/cosmic/libqt5opengl5
