ERROR: Hash value integrity check failed

[Brian S]

Hello all,

I'm relatively new to munki and still working through how to get things setup, organized, fixed, etc.  

Right now we're populating a number of packages into the repo.  I am now getting a "hash value integrity check failed error" on a package.  I've not only removed it from the repository and re-added, but I've downloaded the package form the vendor fresh and I still get this error.  If I download the dmg to a client and install it works fine, just not through munki.

Any suggestions?

Brian S.

Is it a writable .dmg?  I suspect it is.  Make a copy of it, mount the copy and try dropping a file in there.  If it works, you have yourself a read-write .dmg and need to convert it to read-only.

You're right!  It's writeable.  So munki only works with read-only dmg's or is this just sometimes a problem if they are writeable.  

Thanks!

Brian

... off to convert my dmg to ro

Every time you mount a rw .dmg, the hash for the file changes, so munki will always think it is invalid due to the hash changing.  Its great fun!

Thanks for the tip.  I just converted to read-only and it's installing now after being reimported.  I will file this one away.  I wouldn't think the hash would change unless you change something, but it makes sense that any kind of touch might change the hash.

Thanks again!

Since this pops up from time to time, I've committed a change such that makepkginfo will now print a warning if given a read/write disk image:

% ./makepkginfo /Users/gneagle/Downloads/foo_rw.dmg

WARNING: /Users/gneagle/Downloads/foo_rw.dmg is a writable disk image. Checksum verification is not supported.

WARNING: Consider converting /Users/gneagle/Downloads/foo_rw.dmg to a read-only disk image.
