That’s where I copy/pasted the code that caused the error message above from (with the 3.32.9 release number edited in). In fact, the error above is the SECOND one resulting from codes on that page! If the codes on it actually worked, I wouldn’t have had to start this thread.
RE: your note on the bottom, Is this what I should be entering?

Looking for matches…

You need to find out where you have downloaded and stored the QCAD flatpak and then pass the exact path to flatpak or change to that directory first.
Most likely the file is in your Downloads folder, so this might work:
cd ~/Downloads
flatpak install --user qcad-3.32.9-pro-linux-qt6-arm64.flatpak
This happens to be exactly what the installation tutorial linked above tells you to do. Perhaps you have overlooked that step?
Please understand that a minimal understanding of files and directories is crucial when working with computers and on Linux it’s imperative.
P.S.: Did you purchase the QCAD Professional package you are trying to install? Are you trying to get the free community edition from a trial version? If you can tell us what you are trying to install, we can help more efficiently.
Is there a reason for preferring the ‘flatpack’ version?
Otherwise download and install the QCAD Pro trial version for Linux.
At the bottom right hit the button ‘Remove’ for info on what to remove for the free community edition.
Flatpak is what it (QCAD’s download page) gave me.
Anyway, I solved the problem; I went to my Distro’s Software Manager and found four other CAD programs. Chose one (LibreCAD) clicked install and my uncle’s name is Bob.
QCAD might want to see if they can get themselves a spot in Linux’s Software Manager lists.
