I have been trying to set up UnrealEngine4 for my ubuntu 18.04.5 LTS system. I've followed this tutorial, https://docs.unrealengine.com/en-US/SharingAndReleasing/Linux/BeginnerLinuxDeveloper/SettingUpAnUnrealWorkflow/index.html
I have done everything up until launching UE4 with "./UE4Editor". In this step, UE4 opens up but says that there is no Vulkan installed and closes down again. I have tried to install the drivers and vulkan with this tutorial, https://linuxconfig.org/install-and-test-vulkan-on-linux. The problem here is that when I type "$ sudo apt install nvidia-graphics-drivers-396 nvidia-settings vulkan vulkan-utils" in the terminal, it gives the following error.
Reading package lists... Done
Building dependency tree
Reading state information... Done
E: Unable to locate package nvidia-graphics-drivers-418
E: Unable to locate package vulkan
No idea how to fix this. Please help.
That driver is proprietary. Consult the manual how to install it.
vulkan package is not something that exists. Probably meant to be libvulkan1, but should be installed as dependency.

I am using a raspberry pi 4.
And I installed a 64-bit (not 32-bit) Raspberry Pi OS.
When I tried to install libjasper-dev using the command
'sudo apt-get install libjasper-dev' as a part of OpenCV.
It is showing "Unable to locate package libjasper-dev".
Does anyone have any idea how to fix this, or how to compile OpenCV correctly on a Rasbian 64Bit ?
For example, this (among other errors) happens when installing the image raspios_lite_arm64-2021-11-08 on an 8GB Raspi4 and trying to follow the instructions on https://www.arducam.com/docs/cameras-for-raspberry-pi/synchronized-stereo-camera-hat/opencv-and-depth-map-on-arducam-stereo-camera-hat-tutorial/:
pi#roverpi:~ $ sudo apt-get install libhdf5-dev libhdf5-serial-dev libatlas-base-dev libjasper-dev libqtgui4 libqt4-test

Package libqtgui4 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

Anyone know how to fix this

I like the idea of having a terminal connected to my nautilus file manager.
There is a package called nautilus-terminal which does this.
if I try to install it via sudo apt-get install nautilus-terminal I get the following error message:
The following packages have unmet dependencies:
nautilus-terminal : Depends: gir1.2-vte-2.90 but it is not installable
E: Unable to correct problems, you have held broken packages.
If I try to install it via sudo apt-get install gir1.2-vte-2.90

Package gir1.2-vte-2.90 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
E: Package 'gir1.2-vte-2.90' has no installation candidate
Does anybody know how to solve this?
This problem is because you already have gir1.2-vte-2.91 installed on your ubuntu but since the package name contains version number, it's not recognized as a higher version of gir1.2-vte-2.90 so you just need to provide a package with the name gir1.2-vte-2.90 and connect it to gir1.2-vte-2.91. This can be easily done by following the instructions of this answer.
I am trying to install openlink vituoso
Inserting below command in ubuntu 16.04,
sudo apt-get install virtuoso-vad-{isparql,ods,cartridges,tutorial}
I have following messages:
Reading package lists... Done
Building dependency tree
Reading state information... Done
E: Unable to locate package virtuoso-vad-cartridges
nothing happens when I do
apt-cache search virtuoso-vad-cartridges
no error , no result!
I have also done
"sudo apt-get update"
and still have the problem
How can I do "sudo apt-get install virtuoso-vad-{isparql,ods,cartridges,tutorial}" without errors?
As noted in the Virtuoso documentation notes for Ubuntu deployment --
Ubuntu have split some of the Virtuoso VAD packages into separate apt packages of their own. When you apt-get install these, all you get is the VAD package on disk ready to be installed into your database; Ubuntu does not install the VAD into any running instance for you (because by this time you might have created your own instances elsewhere on different ports).
That being the case, I would suggest you simply download the VAD packages directly from our download site. You didn't not indicate which version of Virtuoso is being installed, and Ubuntu packaging has historically been some months or even years behind our updates. Guessing you're working with Virtuoso 7.2, please start here. Please comment below if you need the VADs for a different version of Virtuoso (7.1, 6.x, 8.x, etc.).
For further assistance with Virtuoso Open Source (VOS), I strongly recommend the Virtuoso Users mailing list.
(ObDisclaimer: OpenLink Software produces Virtuoso, and employs me.)
