I'm currently having some issues with TKLPatch extracting the ISO. I first experienced these issues with my old (v11.0) based TKLDevEnv so I decided to start again from scratch. I installed TKL Core v11.2 to a new KVM VM (under ProxmoxVE 1.9) and all went well. I installed TKLPatch and all still seemed well, but now when I try to patch an ISO I get errors like this:

tklpatch turnkey-lamp-11.2-lucid-x86.iso concrete5-0.2

I've never had issues like this before. I verified the Fileserver and Core ISOs weren't corrupted. I have tried patching other TKL ISOs and having the same issue. I tried checking the (virtual) disk but that didn't help. I --purge(d) TKLPatch (and dependencies) and reinstalled (after a reboot). I reinstalled the whole VM (from scratch). I've done a full apt-get upgrade. And nothing seems to make any difference...

The strange thing about it is that errors seem to occur in random places (they don't error in the same place) and occasionally the process actually finishes (although the 'zlib::uncompress failed, unknown error -3' erros still occur at random places) but the ISO is useless.

Any ideas??
