[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

Re
Maybe first of all you two write the steps performed for flashing Lollipop Roms? I've tried all the Lollipop Roms compiled for SXS and nor,ally I used to do this way:
1. TWRP recovery (but CWM also worked)
Install TWRP recovery in FOTA partition using Terminal apk provided your phone is running on 4.1.2. kernel supporting TWRP recovery. Flash kernel from ROM zip file prior entering TWRP (this step helps avoiding an error like "update binary...").
2. In TWRP recovery - Advanced - wipe everything but sdcard. In Mount section unmount everything but sdcard.
3. Flash the ROM and wipe Cashe&Dalvik
4. Flash appropriate GAPPS, wipe Cashe&Dalvik and reboot.
that's all

ADB Sideload Issue SM-T217S

So I don't have a MicroSD Card. I am using TWRP 2.7.0.0 and trying to sideload the Lineage 15.1 Oreo ROM. Every time I try it, though, I get:
E3004: This package is for device: lt02lte,lt02ltespr,lt02ltetmo; this device is .
E:unknown command [log]
E:Error executing updater binary in zip '/data/media/0/sideload.zip'
Updating partition details...
Am I doing something wrong? How can I fix this? I am attempting to go to this from the NegaLite ROM.
