i getting following error's during update:

w:gpg error: http://ppa.launchpad.net oneiric release: following signatures invalid: badsig a8aa1faa3f055c03 launchpad ppa daniel richter, w:failed fetch http://ppa.launchpad.net/erik-b-ande...source/sources 404 not found
, w:failed fetch http://ppa.launchpad.net/lkjoel/fix4...source/sources 404 not found
, w:failed fetch http://ppa.launchpad.net/mozillateam...source/sources 404 not found
, e:some index files failed download. have been ignored, or old ones used instead.

how fix them?

except fot first site http://ppa.launchpad.net oneiric release, rest of them not located in addresses given so, better remove them sources.list or through gui interface in system, administration, software origins.

respect first one, have import correct gpg key in launchpad ppa in order updates. if ppa one: https://launchpad.net/~danielrichter...filter=oneiric, have in read installing, way import gpg key: adding ppa system

can update system unsupported packages untrusted ppa adding ppa:danielrichter2007/grub-customizer system's software sources. (read installing)
