    Hello, I am new to both linux and raspberry pi.

    I have installed an Ubuntu 21.04 image on Raspberry Pi 4B 8GB and running SSH into it. Then I followed the instructions to install Rapidscada image into it. However, when i proceed to http://serverip/scada, all i got is Login.aspx downloaded and by opening it, it displays this error:

    This page contains the following errors:
    error on line 1 at column 2: StartTag: invalid element name
    Below is a rendering of the page up to the first error.

    Any idea how can i get it to work? Thanks.

    Did you install Mono from where? Perhaps there is an old version in the ubuntu repository and there are errors on this?

    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.

    I install mono using sudo apt-get install mono-complete, it has errors at first, so i rebooted and try again and it seems succeeded.

    Does raspbian differ from Ubuntu in the process?

    Thanks

    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.

    Hi,

    Does raspbian differ from Ubuntu in the process?

    If you mean the process of Rapid SCADA installation, it’s similar.

    Hello, I have performed sudo apt-get autoremove mono, and then I redone the step shown in the mono-project above, and confirmed the version of mono-devel to be 6.12.0.122-0xamarin1+ubuntu2004b1.

    However, the same problem persists after reboot
    Should I delete and perform everything again? Please advice thanks
