Xcode 8 beta 2 installation error [closed]

Question

I've downloaded Xcode 8, Beta 2 several times and attempted to install it. Each time, I've encountered the following error when attempting to decompress the file:

The operation couldn't be completed. cpio read error: Undefined error: 0

What I've tried:

1. Googling suggested I might have a space issue, so I went medieval on my hard drive and cleared out 40 gigs. The file is a fraction of that, even uncompressed.

2. I ran Onyx and cleaned everything, ran maintenance scripts, repaired permissions, etc.

3. Multiple downloads, thinking perhaps a download might have been corrupted.

Any other suggestions re: what might get this thing working?

Answer 1

I found another 500 megs of files to delete, bringing my free space to 40.5 GB. Upon attempting to open the ~4.5 GB Xcode_8_beta_2.xip after freeing it up the extra space, I was able to uncompress the archive.

I'm leaving here in case someone else encounters the same problem. This version seems to need significantly more free space than past versions I've installed.
