Upgrade to Thunderbird 3.1.4 -corrupt file-rm dir?

[sandlynx]

I just tried to upgrade to Thunderbird 3.1.4, and when I uncompressed the file, it complained that the file was corrupted:
bzip2: Compressed file ends unexpectedly;
perhaps it is corrupted? *Possible* reason follows.
bzip2: Inappropriate ioctl for device
Input file = (stdin), output file = (stdout)

It is possible that the compressed file(s) have become corrupted.
You can use the -tvv option to test integrity of such files.

You can use the `bzip2recover' program to attempt to recover
data from undamaged sections of corrupted files.

tar: Unexpected EOF in archive
tar: Unexpected EOF in archive
tar: Error is not recoverable: exiting now
root@darkstar:/usr/lib/thunderbird-3.1.4#
Since the contents are corrupted, I wanted to remove the dir and make a clean directory. I received the message that said:
rmdir: invalid option -- 'r'
Try `rmdir --help' for more information.
root@darkstar:/usr/lib/thunderbird-3.1.4#
I tried the option "--ignore-fail-on-non-empty because its a non-empty directory. That didn't work. The corrupted directory is still there.
How do I get rid of this directory and it's corrupted contents so I can make a clean directory for another upgrade attempt?

Use rm with -rf option to delete all the contents of folder including subfolders.
Make sure to type correct folder name. Wrong execution of rm -rf can hose your system.

rm -rf <folder>
