Degraded mode allways

[ruben-farma]

Hello all,

When I execute inside jenkins pipeline the next:

• docker run --rm --interactive --volume /var/jenkins-slave/workspace/stagging/stg-pipelines/pipe-calendlyapi-stg:/app /composer install --ignore-platform-reqs --no-dev

Allways I have the error of degraded mode and a very very slow download rate (with all projects)

Loading composer repositories with package information
                                                      Updating dependencies

Retrying with degraded mode, check https://getcomposer.org/doc/articles/troubleshooting.md#degraded-mode for more info

I'm executing on a machine of google cloud, so I discard problem of connection:

IPv6 is disabled:

net.ipv6.conf.all.disable_ipv6 = 1
net.ipv6.conf.default.disable_ipv6 = 1

Also, I do the Workaround Linux: sudo sh -c "echo 'precedence ::ffff:0:0/96 100' >> /etc/gai.conf"

root@jenkins-slave-01:~# grep --color "precedence ::ffff:0:0/96 100" /etc/gai.conf
precedence ::ffff:0:0/96 100

I can do anything more?

Unfortunately this is very hard to reproduce since I do not have access to your host and everything works fine on all of the host machines I own myself.
