Wanted to provide an update.
I didn't have a USB drive large enough to have both Ubuntu and the Installer installed. So I had to find my old PC. I finally got Ubuntu installed. That fixed the issue, I'm updated to OTA-21 now!
Thanks for the help @Lakotaubp
@lakotaubp Sorry I was having issues editing my post. It should have read:
I tried using the RC channel, downloaded "Version 45”, on the phone and it returns a similar error:

I'll try your recommendation and try the UBport Installer from Ubuntu.

Thanks for the response.
First thing if you switch of and restart willit boot back into UT?
Yes
Also which channnel are you on I'm not familier with Volla but we are on OTA-20 for the stable channel at present.
I’m on the “stable” channel. When I try to update from the phone, it tells me downloading “Version 7”, that’s the one giving me the error message.
Which version of the installer? please try 0.8.8 or .9 it could just be a server error or some such.
I’ve tried both 0.8.8 and 0.8.9 and they both hang during the firmware flashing phase.
I don't know if it makes a difference, but I'm running the UBports Installer on a Mac running Mac OS 10.13.6.
Adding another data point. I'm in the Bay Area of Northern CA and get 2G when using a T-Mobile SIM card and no service with an AT&T SIM card.
I opened my Volla Phone today which is on Ubuntu 16.04 (OTA-14) and tried to update the phone and keep getting the following error:

I also tried using the UBports Installer following the instructions https://volla.online/en/resources/manuals/How-to-flash-Volla-OS-on-Volla-Phone.pdf to reinstall Ubuntu Touch, but it gets stuck during the flashing phase.
Any idea what my issue is? Is there any other methods for updating Ubuntu Touch? Thanks in advance.
