I have software that's been running and making .tar downloads for about 4 years. nothing has changed on the server. i admin to it so i'm pretty sure. for some reason today one of the tar's won't unpack. i tried on OSX and CentOS using different versions of tar. i keep getting the following no mater what I try:

¿$ sudo tar -xf 101108103122.tar
tar: Skipping to next header
tar: Archive contains obsolescent base-64 headers
tar: Read 737 bytes from 101108103122.tar
tar: Error exit delayed from previous errors

any ideas? can i skip the corrupt file and move on?

$ sudo tar --ignore-failed-read -xf 101108103122.tar
tar: Skipping to next header
tar: Archive contains obsolescent base-64 headers
tar: Read 737 bytes from 101108103122.tar

using the process of elimination i was able to determine that a specific file in the archive was causing the problem. so just removing that one got me a clean tar. no idea why that file is causing the error. looks like a tar bug. thanks!

Is your TAR file password-protected? If yes, then it will be harder to recover it.

what does `file 101108103122.tar` show?

you may need to use a different option, do you know what the command was that created the archive?
