When I go into the terminal and type apt-cache policy opera-stable, it detects my current version and it detects also that there should be a later version, "Candidate: 98.0.4759.6", as seen on the picture below.

When I run an update on my computer, as seen on the picture below, Opera browser is nowhere to be found, even though every other software I installed, even from outside my distro's repository receive updates normally.

I even checked in "Software & Updates", whether the repository of Opera is there, and it is there and active, as seen on the picture below, so I don't understand what the issue might be. Opera is the only proprietary browser I like to use due to the free VPN service, however I cannot really use it like this since using it without the necessary security updates poses a risk. I would be very glad if someone from the Opera team could fix this so I could continue using this great browser!
