Companion update says failure to authenticate isc-dhcp-server


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.

After this operation, 795 kB of additional disk space will be used.
WARNING: The following packages cannot be authenticated!
E: There are problems and -y was used without --force-yes
Failed to install isc-dhcp-server; Aborting update

is there anything im doing wrong or need to do before this update to allow for authentication?

thank you!

Hi @RoyceRobotics, welcome to the forum :slight_smile:

This isn’t an error I’ve seen before, so I had a search around online and it apparently tends to occur when a mirror/download server is down or otherwise unavailable. If that is in fact the case there’s not much we can meaningfully suggest beyond either trying again later, or instead doing a manual install where you flash the Raspberry Pi SD card with a pre-built image.

Hope that’s helpful - let us know how you go :slight_smile:
