Stuck in the last step

[Turbo7785]

Hello there.

After the two first steps successful, I get this error messages trying to
"sudo dpkg -i octoprint-tft_0.1.2-1.jessie_armhf.deb"

After sending this command, this appears:

pi@octopi:~ $ sudo dpkg -i octoprint-tft_0.1.2-1.jessie_armhf.deb

Errors were encountered while processing:

I've tried with sudo apt --fix-broken install without success.

Could you guys help me with this? I don't know so much about coding...

Thanks for your attention

...sounds like the file is incomplete. Try re-downloading the .deb, it should be 2250008 bytes big.
if wget https://github.com/mcuadros/OctoPrint-TFT/releases/download/v0.1.2/octoprint-tft_0.1.2-1.jessie_armhf.deb gives you an error, try: curl -LO https://github.com/mcuadros/OctoPrint-TFT/releases/download/v0.1.2/octoprint-tft_0.1.2-1.jessie_armhf.deb

Sorry for the late reply, but I've been very busy with work and so.
Thank you so much for the help, it worked flawlessly!
Now I have a problem with the reaolution, but I'll try to deal with it later.
