Synaptic not feeling well

[דותן כהן]

This message is posted two two lists as I am quite uncertain as to
which of them would be less unappropriate.

Today, when I went to open synaptic from the kde menu on FC3, I
noticed that it was missing! So I opened it from a terminal, but
cannot update- no matter what I try to update I get this error (or one
vey similar):

APT system reports:
E: Unknown signature
/var/cache/apt/archives/taglib_0%3a1.3.1-1_i386.rpm: (SHA1) DSA sha1
md5 (GPG) NOT OK (MISSING KEYS: GPG#1ac70ce6)
E: Unknown signature
/var/cache/apt/archives/amarok_0%3a1.1.0-2_i386.rpm: (SHA1) DSA sha1
md5 (GPG) NOT OK (MISSING KEYS: GPG#1ac70ce6)
E: Error(s) while checking package signatures:
0 unsigned package(s)
2 package(s) with unknown signatures
0 package(s) with illegal/corrupted signatures


Um, what can I do? I should probably mention that I have about two
weeks of linux experience under my belt.

Thanks.
