curl: (60) server certificate verification failed. CAfile: /etc/ssl/certs/ca-certificates.crt CRLfile: none
More details here: http://curl.haxx.se/docs/sslcerts.html
curl performs SSL certificate verification by default, using a "bundle"
of Certificate Authority (CA) public keys (CA certs). If the default
bundle file isn't adequate, you can specify an alternate file
using the --cacert option.
If this HTTPS server uses a certificate signed by a CA represented in
the bundle, the certificate verification probably failed due to a
problem with the certificate (it might be expired, or the name might
not match the domain name in the URL).
If you'd like to turn off curl's verification of the certificate, use
the -k (or --insecure) option.

It seems that musl switched to Let's Encrypt(?), signed with a root certificate that's not included in Ubuntu 16.
When trying to build this image, I got the following error:
It seems that musl switched to Let's Encrypt(?), signed with a root certificate that's not included in Ubuntu 16.
Installing the Let's Encrypt R3 intermediate CA (cross-signed) helps. I downloaded it from https://letsencrypt.org/certs/lets-encrypt-r3-cross-signed.pem.
