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 was installing atom on Ubuntu 18.04.1 using the command:-
sudo apt-get install atom
I stopped the installation process and now whenever I run the command:-
sudo apt update
The following is the output:-
Hit:1 http://ppa.launchpad.net/webupd8team/atom/ubuntu bionic InRelease
Reading package lists... Done
Building dependency tree
Reading state information... Done
All packages are up to date.
Whenever I try to install Atom again, I get the following output:-
Reading package lists... Done

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:
The following packages have unmet dependencies:
atom : Depends: gvfs-bin but it is not installable
E: Unable to correct problems, you have held broken packages.
Now, whenever I try to install a package from the terminal using
sudo apt-get install <package-name>
I get some output showing: This package has no installation candidate.
For example, if I install rpm, the output is:-
Reading package lists... Done
Building dependency tree
Reading state information... Done
Package rpm 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 'rpm' has no installation candidate
All this has been happening since the day I terminated the atom installation.
Can anyone help me with this?
