[Q] Stuck in Recovery, can't flash ROMs

Decided to resurrect my old Verizon GNex, and found that it will only boot to TWRP recovery. Was able to successfully sideload a ROM zip, but attempt to flash produces the following result (copied from phone screen, site won't let me link screenshot):
Formatting /system
Extracting /system
Symlinking
set_metadata_recursive: some changes failed
E:Error executing updater binary in zip '/sdcard
Error flashing zip '/sdcard/sideload.zip'
Updating partition details...
Failed
Any ideas on how to proceed?

First copy ROM on sdcard, then wipe all except sdcard, and then try.

[Q] Wiped /sdcard and /system - only have CWM now. How can I proceed?

I had an older custom ROM and CWM 6.0.10 and I wanted to update to a newer 4.4 ROM (Omni) so I booted into recovery and proceeded to do a factory reset along with a format of /sdcard and /system. Now when I reboot, I enter recovery automatically.
I managed to push the ROM .zip to the phone using "adb push ROM.zip /sdcard/ROM.zip". The problem is that when I try to install from zip (withing CWM) the install fails with this message:
SymlinkingApplyParsedPerms: removexattr of /system/addon.d/50-hosts.sh to 0 failed: Operation not supported on transport endpoint
script aborted: set_metadata_recursive: some changes failed
set_metadata_recursive: some changes failed
E:Error in /sdcard/omni-4.4.4-20140825-maguro-FML.zip
(Status 7)
Installation aborted
I'm stuck here and I'm guessing that I shouldn't have formatted /sdcard and /system as the directory "/0" that the error message refers to isn't on /sdcard anymore (it used to be). Not sure what to do at this point.
I've tried flashing TWRP, but fastboot waits forever with a "<waiting for device>". I thought TWRP might let me sideload the ROM (I was thinking that this manner of installing might create some default partitions on the SD card, as needed.
I welcome any suggestions. BTW, this is all on a Galaxy Nexus GSM

error executing updater binary

trying to flash a cyanogenmod rom onto my rooted phone with TWRP.
Everything okay up to the point on installing the new rom (a zip file).
here's what i get as an error message:
***********
E:Error executing updater binary in zip '/sdcard/<rom_name_here>.zip'
error flashing zip
updating parition details...
...done
****************
I've tried with all the recent cyanogenmod builds for the htcone m9 and I get the same error everytime. Even when i try to sideload from my computer in adb.
I've also seen this error in other forums and they have suggested doing certain wiping procedures and reboots, but I've tried them all and I've gotten nowhere.
any ideas?

You need to use this twrp. Then it will work. About twrp errors: just ignore...

I've already used also that TWRP version
twrp-installer-daisy-3.3.0-0-offain.zip
KO
