Hi all,
I never used PPA repository before.
I use a software (CCTV-VIEWER) that I installed thru SNAP.
I found that it can be installed thru other ways too.

I research a little about PPA and would like to try it. I search on this forum here and also elsewhere. Among articles that I found/read.

I tried it in Bullseye and Bookworm. And got the same errors.
.
The file briefly appeared in /etc/apt/sources.list.d/ and then disappeared.
I checked that root has write permission to the location, and just for troubleshooting only - I relax the permission to everyone. Made no difference.
Is there any steps that I missed?
