Certificate Expired

[94d7rzmswk-dot]

Good day! I'm trying to install the ATTinyCore in my Arduino IDE and it's complaining about your certificate being expired. 🙍‍♀️ Is there a safe place to download your .zip package?

There is a formal report about the problem here:

SpenceKonde/megaTinyCore#1259

There are instructions for working around the problem here:

Hi there,

The certificate has now been renewed and AttinyCore shows up in boards manager again. However I now get the following error when attempting to install via boards manager:
Tool arduino:avr-gcc@7.3.0-atmel3.6.1-arduino7 already installed
Downloading packages
arduino:avrdude@6.3.0-arduino18
ATTinyCore:micronucleus@2.5-azd1b

There has been an Issue report opened with people experience the same problem:
#919
