As I said last night, that now appears to be working.

The odd thing is, that the encrypted file is a .tar.gz.asc which was
copied 
from a USB flash drive. Decrypting it results in a .tar.gz file. When I
apply

tar -xvf filename.tar.gz

to this file on the system I'm playing with tar gives me error messages
- 
can't remember exactly what they were. It's an old system that was given
to 
me with a 20GB ATA drive and ME installed on it. I replaced the
motherboard 
with a fanless Via mini-ITX unit that was reliably running 24/7 in a
server 
before I upgraded it a few weeks ago. The main reason for replacing the 
motherboard is that it has more memory than the original.

When I take the same decrypted tar.gz file back to my desktop machine on
a 
flash drive and again run tar -xvf on it, it unpacks without errors.

Is there any chance the errors could be caused by the ancient hard
drive? I've 
also got the 80GB SATA hard drive that was running in the server with
the Via 
board. I might try putting that in the old machine and doing another
install 
but I've got other things that I really ought to be progressing right
now.

I guess I should also try the tar operation with my laptop.

This sort of thing worries me a little, because that tar file is my
backup of 
my home directory, which includes the home directory of my server with
all my 
email messages.

Dave,  try this:  tar -tzvf file.tar.gz.


The -t option  means test. It will test the archive and will tell you if
the archive is corrupt or not.
