getting curl certificates error running docker build

[mgitman]

I'm running Ubuntu 20.04.6 LTS on an Azure Lab Services VM. I've downloaded hbase-docker. I run:

sudo docker build -t dajobe/hbase .

And I'm getting this:

14.22 curl: (77) error setting certificate verify locations:
14.22   CAfile: /etc/ssl/certs/ca-certificates.crt
14.22   CApath: /etc/ssl/certs

I'm doing this for a class. What's interesting is that this had been working for my classmates up until some time in late February or early March, and then whatever the date was, those who tried it after that started seeing this same problem. My classmates have the same setup with their own VMs.

I've inspected the ca-certificates.crt file and the certs directory, and I see nothing untoward in terms of permissions or contents.

If anyone has any idea what's going on, I'd appreciate it. It would be helpful even just to be able to reproduce the problem with the constituent simple commands outside the context of the docker command.
