Im working with some older ROV2s that have been sitting for a good while at the university im working on them from. Im trying to get them up and running and currently facing this problem with one of them where when I go to download the update from the companion website it loads until I get this same message every time:
E: Some index files failed to download. They have been ignored, or old ones used instead.
