Apt update - invalid signatures - fresh system reinstall

Performed a fresh install on the Rosbot 2.0 Pro per these instructions:
ROSbot ( 2R | 2 PRO | 2 ) | Husarion
Upon reboot performed a “sudo apt-get update” and got and invalid signature error from the husarion repos.

Is this cause for concern?

It may be a problem if you use Husarnet, but the fix is simple, the following is just a snip from my robot build procedure.

If during apt update an error is encountered relating to ‘husarnet signature needs updating’ do the following:
To update the key/signature:
i. su root (The following command needs to be run as root)
ii. curl https://install.husarnet.com/key.asc | apt-key add -
iii. ctrl d to revert to husarion prompt (The following command should’t be run as root)
iv. sudo apt update

The information relating to the above can be found here:

Robin,

Worked like a charm.
Thanks a bunch!!!

Only variation I had from your instructions was from i.
I used “sudo su root” not “su root”

Thanks a bunch
Will definitely be referring back to this page when doing a fresh install
