SOLVED: Error when trying to upload to UNO

This is a fresh install of IDE 2.0.0-beta.3

I am trying to upload the basic Blink example to a genuine Arduino UNO

Compilation is successful, then it appears nothing is happening for a long time, then all of a sudden all 10 of these getsync() attempts fill the log at once.

Here is the error I get, shortened to the last entry for brevity. The first 9 attempts are identical.

...
avrdude: stk500_recv(): programmer is not responding
avrdude: stk500_getsync() attempt 10 of 10: not in sync: resp=0xbb
Upload error: Error: 2 UNKNOWN: uploading error: uploading error: exit status 1

Apologies, but I solved my own problem. I must have been tinkering with this board in the past and forgot what I had done. Reflashing the bootloader fixed the problem.

Apologies for the waste of a forum post

No worries. I'm just glad to hear you found the solution. Thanks for taking the time to post an update.
