I don’t think mine is a third party distribution, so I don’t think the errors I’m getting are because of that. When I run scripts/linux/ubuntu/install_dependencies.sh, I first get a few “service unavailable” and “The following signatures couldn’t be verified because the public key is not available” errors followed by “Some index files failed to download. They have been ignored, or old ones used instead.” I don’t know how much of a problem this is.
I then answer “Yes” to the question “Your system is not updated, that can create problems when installing the OF dependencies. Do you want to update all the packages now?”, after which I get a large number of ROS packages saying they “failed to fetch” and “service unavailable”. I am not sure if I should try to fix this or of updating the system is really necessary - maybe I should just answer “No”?
Then when installing dependencies, I also get the following error:
E: Unable to locate package libgl1-mesa-dev-hwe-16.04
E: Couldn’t find any package by glob ‘libgl1-mesa-dev-hwe-16.04’
E: Couldn’t find any package by regex ‘libgl1-mesa-dev-hwe-16.04’
error installing libgl1-mesa-dev-hwe-16.04

this seems an error with your distribution repositories but you can also
report an issue in the openFrameworks github
I’m not sure what “error with your distribution repositories” means I should do.
