Hello,

I am trying to get my Stretch robot back to ROS1, as the demos I had written for the robot do not work in ROS2. I reinstalled Ubuntu 20.04, but I keep getting the following message when I try to run the new robot install script. Does anyone have any tips for what could be happening?

Hey @jgangemi, thanks for including the logs. Are you still seeing this issue? Often, the “Apt update & upgrade” step can take a while since it’s pulling a lot of software/data from the Apt servers.
