[Solved]Arduino error when updating library

I received a prompt to update the library but although there was some success there was a failure notice as follows:-

Tool arduino:avr-gcc@7.3.0-atmel3.6.1-arduino7 already installed
Tool arduino:avrdude@6.3.0-arduino17 already installed
Tool arduino:arduinoOTA@1.3.0 already installed
Downloading packages***
arduino:avr@1.8.6
Failed to install platform: arduino:avr.
Error: 2 UNKNOWN: Get "http://downloads.arduino.cc/cores/staging/avr-1.8.6.tar.bz2": dial tcp 104.18.13.241:80: connectex: An attempt was made to access a socket in a way forbidden by its access permissions.

Can anybody interpret that for me (as a novice in these things).

As you may have found with internet searches, they indicate virus scanners are the possible issue (see the last line of your post/codetag)... so maybe disable your antivirus before updating the library, then re-enable the antivirus?

Thanks xfpd, I will try that.

You can remove the offending library by following this guide Uninstall libraries from Arduino IDE and then reinstall it manually to see if it reolves the issue.

Note: it is best to use the lastest version of IDE 2.

Thanks Dozie,
I will try that when I can get Arduino to open! (I've opened a separate topic on that).

I've had trouble with my laptop generally (all apps) so today I spent time trying to resolve issues (not being a computer whizz it's been trial and error) and eventually the laptop is now behaving.

I realised that although I thought I had disabled anti-virus etc I hadn't gone deep enough. Having done that I uninstalled and re-installed IDE 2.0.3 and it appears to have solved the issues (very slow to open, wouldn't download library and updates).

Fingers crossed!
