In Ubuntu 22.04 Remmina is requesting approval locally. Can it be bypassed?

What are you doing on the remote systems that needs the full desktop session? There may be a sleeker solution to what you want to achieve

Hello! Thank you for trying to help!
As I mentioned, I have about 15-20 different mini computers spread around and used for different purposes. None of those have a monitor, keyboard or mouse.
Seven of these are use for surveillance. Each one is monitoring up to eight video cameras and recording events on a local HDD. I need to log in occasionally to monitor the video streams, modify the settings for the cameras or copy the recorded video data to a server.

I have other ones monitoring a greenhouse, pond, sprinklers, etc. Those I could possibly connect to using ssh, but the monitoring software is graphically based, so I would need to change that if ssh will be used.

Some of those are used to run the very few Windows applications that I use. I have tried to get these applications to run within Ubuntu and failed. Most of those are engineering applications like Mentor Graphics schematic capture, layout and simulation. Those are not really an issue, because rdp does not request locally for permission to allow an external user to log in.

I have several other systems monitoring experiments and tests in progress, where I need to log in remotely to check on the status.

Right now, I was trying to set up a remote system with Ubuntu 22.04 so that everybody here could log in remotely and decide whether they wanted to upgrade their systems to Ubuntu 22.04. Yes, it can be done on their systems using a CD or a USB flash drive to 'try' Ubuntu, but we need something where testing can be accomplished over some time. We need a system to check software compiles, experimental implementations over time on a system that can be 'trashed' if there is a problem with the new version.

Unfortunately, the new 'feature' in Ubuntu 22.04 have made Ubuntu 22.04 useless to me, unless there is some kind of a solution to bypass this query...

Is that not done by a Web browser? Just trying to work around the issue unless someone else with experience can jump in

Well, I am trying to keep these systems disconnected from the Internet for safety issues (in particular the surveillance). That is why I am using minicomputers with two Ethernet ports, with one dedicated to the surveillance cameras. This port is blocked from access to the extranet for security purposes. The only way in which I can connect to the cameras is to use the local Firefox that can then connect to the specific cameras on the dedicated Ethernet port. I do have similar arrangements on the engineering test systems, etc.
The only way that I can see that this problem can be solved is a possibility to disable the local approval request to connect remotely to the system. This particular implementation made Ubuntu 22.04 completely useless for remote access...
As far as I can see right now, Ubuntu 20.04 will be the last version that I can use here...

At this moment I need to declare Ubuntu 22.04 as completely useless for remote systems...

If you say so. Millions would disagree heavily.

I doubt that. Accessing remote computers without a local user present is a must for many applications in many industries. I have more than 60 electrical engineers that I work with in agreement about this, as well as more than 300 of my students. They were actually the ones who brought this issue to my attention...
At this moment, we are all locked to Ubuntu 20.04 until we find an alternative operating system for our remote computers. Hopefully it will be sooner than later.
