Unable to update Mac client to 1.45

I am trying to update the MacOS Netdata client from 1.44 to 1.45, to take advantage of new features.
My Mac is running
Darwin server1.local 19.6.0 Darwin Kernel Version 19.6.0: Mon Aug 31 22:12:52 PDT 2020; root:xnu-6153.141.2~1/RELEASE_X86_64 x86_64
Which is a rather old Catalina 10.15.7

However it will not update.
I installed it originally using the regular method curl https://get.netdata.cloud/kickstart.sh > /tmp/netdata-kickstart.sh && sh /tmp/netdata-kickstart.sh --stable-channel --claim-token ....

I had to update/install somethings like
brew install libuvl
brew install libuv
But it did install and work fine.

I am following the details on Update Netdata | Learn Netdata to update using sudo ./netdata-updater.sh

Here is some of the output

server1:netdata mike$ sudo ./netdata-updater.sh

Then the first errors appear some moments later
