The two packages, mepis-auto-6.0 and mepis-init-6.0, are listed under "installed (upgradable)" in Synaptic. However, when I select these two packages and click on "mark for upgrade" I get a warning dialog saying that these two packages cannot be authenticated. Also, when I clicked on the Reload button I got the following message:
"W: GPG error: http://apt.mepis.org
mepis Release: The following signatures were invalid: BADSIG D3F985C51A77B3E9 Warren Woodford (MEPIS Maintainers) <email@example.com>".
So, what is the meaning of this?
