octoprint.log, serial.log or output on terminal tab at a minimum, browser error console if UI issue ... no logs, no support! Not log excerpts, complete logs.)
Can you also upload plugin_softwareupdate_console.log ?
You'll want to fix this too: !!! UNDERVOLTAGE REPORTED !!! Make sure that the power supply and power cable are capable of supplying enough voltage and current to your Pi.
I was trying to run them straight from octoprint notification. I have changed my input power and have not seen the under voltage on the end of the log anywhere.
Actually an undervolatge issue prevents updates of any kind.
