It is necessary to look at the mono version, sometimes in the repositories the version is much younger than is required for Scada to work. Therefore, it is better to install Mono from the developers ‘ site. In the text document, there is an example for connecting a repository in Debian. But it is probably also suitable for Ubuntu, you should try it.

In fact, I would recommend using raspbian, because in my experience, all third-party systems most often have errors in the builds, since people do not pay enough attention to the work at 100%, simply because they can not test absolutely everything.
Did you install Mono from where? Perhaps there is an old version in the ubuntu repository and there are errors on this?
Configuration Database-Directories-Event types
Add your event and specify your color, or use the ones that are there
In the input channel 177, use a formula like this
Val();Val()>0? SetStat(177,116):SetStat(177,117)In this way, you change the channel status number to your own, to which the colors are linked.

What do developers in India mean? you can install and configure Scada remotely, only a person who will connect the wires and an IT specialist are needed on site
This mechanism does not work in Linux. I haven’t checked what doesn’t work yet. Raspberry is too slow a PC to configure scada directly on it, it is easier to run a project on your Windows PC and upload it to a remote server.
The interface works, but there are some problems with the display and for the Linux version these mechanisms are disabled. For example, in the settings there are no drop-down menus with a selection of preset values, you must enter numbers. You can make a cheat sheet for all parameters and look at it when setting up, but this is very inconvenient. We expect version 6, where it will probably already work in the GUI on Linux without these inconveniences. All applications running under Mono run as written above, in theory, you can make symbolic links to run.
Change the owner for all folders and files in the folder.
sudo chown -R user:group /path/to/dir/Where user is the new owner and group is the user group. -R indicates that the rights must be changed recursively.
Example for Raspberry and install in /opt
sudo chown -R pi:pi /opt/scada
on the remote server, I gave the entire scada folder to the system user with ID=1000, that is, this is the user that you create in the system, for example, for Raspberry Pi, this is the pi user. I also added this user to the www-data group just in case.
Probably the folders above the level do not have the appropriate rights, and it does not even reach the final Config folder. Just doesn’t let it go any higher.
Very strange. when the server is restarted, the command is executed from the root user in theory. Perhaps the web user does not have enough rights, but it is already necessary to see what is there with apache2 in the settings. We need to think about it…
