cannot install texlive

[Bradley D. Keister]

I'm continuing to get this error, have retried many times with different 
mirrors:

./install-tl: signature verification error of /tmp/RbnRUBCIUk/itXBdaaeS7 
from

failed. Output was:

fatal: getcwd failed: No such file or directory

Please try from a different mirror and/or wait a few minutes
and try again; usually this is because of transient updates.
If problems persist, feel free to report to texlive at tug.org.
