I’ve tried this several times with the same result (BTW it would be helpful if you provided the installation link in the tutorial as text to cut and paste rather than just as an image)
https://cayenne.mydevices.com/rpi/rpi_d1vv7p72k9.sh is just an example install script in the guide. You will need to follow the instructions in the guide and use the URL that is generated for your account.
The text you typed into the terminal was just example text used in the tutorial. Once you sign into your account at https://www.cayenne-mydevices.com/signin/ you’ll be given your unique code that you will type into the terminal and begin your download. Let us know if you continue having trouble here! Thanks and welcome to the Cayenne community!
Following your helpful guidance I logged in to my account and carried out the installation (may I suggest amending the Cayenne Documentation page by adding a link to the signup page?) .
Unfortunately the process stalls at “Installing myDevices agent”
I have used sudo raspi-config /Expand Filesystem which reports (correctly) that the installation was done through NOOBS and that the Filesystem is thus already expanded.
Can I recommend that you start a new thread for your difficulties since this one has been marked ‘Helped’.
Also if you could provide some more information as to where you are trying to install from, (windows, mac, android, iOS, raspian or other) and a little about your raspberry ( a, 2b, 3b, zero, or other) and how it is connected to the 'net (WiFi, cabled) that will help the community with helping you attain your goals in discovering all that makes Cayenne wonderful.
