    1. trying to install my company's software package which uses curl.

    linaro@linaro-alip:~$ sh -c "$(curl -L "https://downloads.remote.it/remoteit/install_agent.sh")"

    curl: (60) SSL certificate problem: unable to get local issuer certificate
    More details here: https://curl.haxx.se/docs/sslcerts.html

    curl failed to verify the legitimacy of the server and therefore could not
    establish a secure connection to it. To learn more about this situation and
    how to fix it, please visit the web page mentioned above.

    2. but certificates are installed?
    linaro@linaro-alip:~$ sudo dpkg -s ca-certificates
    Package: ca-certificates

    I have a Tinkerboard running Debian 9 Stretch and finally got it working OK.  I use it as a test platform for my company's Linux security software.

    Now trying Tinkerboard S with the following:

    linaro@linaro-alip:~$ uname -a
    Linux linaro-alip 4.4.194 #52 SMP Tue Oct 26 08:35:58 UTC 2021 armv7l GNU/Linux
    linaro@linaro-alip:~$

    I've installed XRDP but only get a black screen when connecting.  I had the same issue on the Tinkerboard and was able to resolve it following instructions at this page:

    https://ubuntututorials.org/ubuntu-20-04-xrdp-black-screen/

    However, I'm still not getting anything from RDP on this device.

    I used this article to increase the number of "inotify watches" to 16384 since I kept getting errors related to that.

    I'm also trying to run tightvnc server but keep getting font errors:

    linaro@linaro-alip:~$ tightvncserver :1
    Couldn't start Xtightvnc; trying default font path.
    Please set correct fontPath in the tightvncserver script.
    Couldn't start Xtightvnc process.

    There is something I find strange when I flash the TinkerOS with Etcher. There are 2 volumes created with a small one where you can find some files and directories you can read with Windows explorater and a big one you can't read with Windows explorater. I suppose on the big one there is the kernel. 

    This is normal for many SD card based Linuxes such as Ras Pi or Jetson.  Some have more than two partitions, I don't know why.  You are seeing two partitions.  The boot partition is small and is compatible with Windows.  The other partition holds most of the files and is a Linux partition, not readable by Windows.
