I follow your solution and now i got
Invalid zip file format
I think I did the same mistake. You have to zip the 6-7 things that are inside the “e-0.5-n-…” folder and not the “e-0.5-n-…” folder.

better but not good.

What kind of update do you do ? Is your device a A/B device ? If yes, I was wrong, because I thought your TWRP was installed correct.
There are several guides how to install TWRP on a A/B device like this (for tissot)
1)fastboot boot recovery.img (https://dl.twrp.me/tissot/twrp-3.3.0-2-tissot.img)
2)Change Partition slot using twrp[Reboot–> Change_Slot]
(for example, if you’re in slot A, change it to Slot B and Vice versa)
3)flash twp-installer.zip (https://dl.twrp.me/tissot/twrp-installer-3.3.0-2-tissot.zip)
4)fastboot reboot recovery (else do it manually by hardware key combination power+volume up)
-
copy ROM to device via MTP (file manager of PC)
-
flash ROM via recovery

I don’t have the feature Reboot/Change_Slot on my TWRP device so I suppose that my device is not “A/B device”
mhm, I’m a little confused and I think I can’t find a solution for your device/problem. But I have found this here in forum. Hope it will help you
Thank you for your help @harvey186 
I try that too but I unfortunately whatever the ROM I try to flash the result is the same 
Hello, i got strange errors flashing my sony XA2. Maybe this works on your device too:
type these commands in a console on your computer:
fastboot boot twrp-3.3.0-2-tissot.img (this will boot TWRP but not flash)
adb shell twrp sideload (this will prepare twrp to receive ROM)
adb sideload e-0.5-n-201905099519-dev-onyx.zip (you have to be in the directory where this file is)
Wait until it’s ready (if this works)

My 2 cents: I flashed yesterday my OPX following this method without trouble. (twrp3.3.0.0)
Which version of adb are you using?
The only difference I notice: My working directory was /home/Download so I just type:
adb sideload e-0.5-n-201905099519-dev-onyx.zip
not the full path to the file

I also try everything from a PC instead of a Mac but no more success
I’ve been using adb 1.0.39 to flash, so I don’t think your problem is here…
In TWRP did you try to tap Wipe > Advanced Wipe, select “System”, “Data”, “Cache” and Swipe to Wipe
Yes Manoj thank you.
I follow the steps mentioned in the wiki https://wiki.lineageos.org/devices/onyx/install
The ‘Smartphone-mail-in’ program will start soon. Dates once finalized will be announced on all channels.
Thank you @manoj, I will wait with my brick until the program start.
Let me know if you need a crash test candidate
