The CRC is a simple checksum to detect transmission errors in the ASCII
armor (the "----BEGIN PGP......-----END PGP..." text format often used
to transfer keys).  The CRC is used to detect such errors before the
data is processed by the actual OpenPGP software (which would also
exhibit an error then).

Common reasons for such an error is mail software mangling the data in
the transfer.  You may use the gpg option --ignore-crc-error to, well,
ignoire the error but in almost all cases you will then get another
error from the actual OpenPGP parsing part.

Not by means of the CRC.  Manual inspection may reveal obvious
problems.  You better ask the sender to send the key again.
