I got this problem:
W: A error occurred during the signature verification. The repository is not updated and the previous index files will be used. GPG error: http://packages.linuxmint.com maya Release: The following signatures were invalid: BADSIG 3EE67F3D0FF405B2 Clement Lefebvre (Linux Mint Package Repository v1) <firstname.lastname@example.org>
Any ideas as to what caused it or if I should worry?
If so, do I need to do a R/R to make sure I am not contaminated?
