Aha, it’s a TLS handshake failure stemming from an “invalid session ID.” Cloudflare can occasionally get a bit picky with connection parameters like this. Classic HTTPS drama. OpenSSL 3.0.x on Ubuntu might not play well with some edge cases in Cloudflare’s config.
Let’s force wget and the repo connection to downgrade the TLS version. Configure this in your machine to avoid the error without compromising general system security:
Create a file for wget configuration:
sudo nano /etc/wgetrc
Add these two lines at the top:
check_certificate = on
secure_protocol = TLSv1_2
Give it another go with the installation script:
bash <(wget -qO- getamp.sh)
Let me know if this gets us talking to the Cubecoders repo properly this time!
