I am trying to install qt 5.15 on zorin os because it is needed for some program to run.
I try to add qt 5.15 on my system by doing the following:
- Adding the repository:
sudo add-apt-repository ppa:beineri/opt-qt-5.15.2-focal
- Then update:
sudo apt-get update
But when I run the command in the second step it gives the following error:
E: The repository 'https://download.qt.io/official_releases/Qt/5.15/5.15.2/zorin focal Release' does not have a Release file.
N: Updating from such a repository can't be done securely, and is therefore disabled by default.
N: See apt-secure(8) manpage for repository creation and user configuration details.
I then added the --allow-insecure-repositories flag to the update and upgrade command but that gave me a new error which is:
W: The repository 'https://download.qt.io/official_releases/Qt/5.15/5.15.2/zorin focal Release' does not have a Release file.
N: Data from such a repository can't be authenticated and is therefore potentially dangerous to use.

E: Some index files failed to download. They have been ignored, or old ones used instead.
I am running Zorin OS 16 Core which is build on Ubuntu 20.04.
I am aware that Zorin OS 16 Core comes with Qt 5.12 but that is a version that I do not need for the program to run.
How do I install Qt 5.15 on Zorin OS properly? I checked and Qt 5.15 doesn't have a directory in the /opt directory.
