Software update failing to download repository information

Support & Help Requests
#1

Had this previously and the community assisted me as the issue was with Chrome.

Only change I have made is that I have updated Brave to the new Chromium platform when I received the notice that the previous version was no longer supported and the Brave icon was greying out.

In the sidebar of "your topic is similar", I saw this post and tried that to see if it rectified the issue. I then ran the Software Updater again and got the same message.

Screen shot attached of the error message I am getting. I suspect it's one of the repositories I have but I have been sticking pretty close to the base install.

Any suggestions on how to correct?

Thanks in advance as always for the assistance.

Quick update to this as I have been working on this.

I un-ticked the repository boxes for Brave and have run upgrade and I no longer get the error message.

There were also 5 packages that needed to upgraded (non Brave) and I have upgraded now.

Tried checking Brave again and it failed. Here are the Details from the error message:

Not sure what I should do on this so asking for the advice. Thanks!
