If you have ever used Docker or any other Linux OCI container system, you inevitably have incurred in the following error:
x509: failed to load system roots and no roots provided

There are two different ways to solve this:
- mount the /etc/ssl/certs folder from the machine where the container is running

I think this is a special moment of the year, where in less than two weeks is possible to meet a huge amount of Open Source contributors in person.
Obviously you will need to take few flights, but it’s definitely worth.
DevConf this year was great.
I’ve been able to assist to a huge amount of talks (more than 20) and the majority of which were very interesting.
As always in conferences, there are themes heavily discussed and other completely absent.
This year at DevConf (like in many others conferences) containers are a very big topic.
The other big topic (related, but different) was Modularization, an approach Fedora is trying to
