Unable to locate package tslib

by hwdornbush on Thu Aug 13, 2020 10:10 pm

I recently received an Adafruit #2441 PiTFT Touchscreen. I would like to calibrate the touchscreen as the touch points are slightly off. I am following
https://learn.adafruit.com/adafruit-pit ... -calibrate

When I try
$ sudo apt-get install evtest tslib libts-bin

I get the error:

Reading package lists... Done
Building dependency tree
Reading state information... Done
E: Unable to locate package tslib

How can I add these packages to my Pi?

I'm getting the same errors...

I'm trying to get my screen to work with OctoPrint (buster)/OctoDash, but the touch controls seem to be rotated separately from the display. I can't figure out how to change the rotation of the touchscreen controls. I can't get into the GUI either to configure the controls as mentioned in the instructions.

I've followed the directions to install and setup the screen. When running apt-get install evtest tslib libts-bin I get the following:

pi@octopi:~ $ sudo apt-get install evtest tslib libts-bin
Reading package lists... Done
Building dependency tree
Reading state information... Done
E: Unable to locate package tslib

I have not been able to get the tslib packages to install. I think this may be why the GUI isn't working, but I'm not sure. Searching the git shows that this was fixed, but it doesn't seem to be fixed.
