I have a number of clear linux servers on a corporate network which go through a proxy to reach the internet.
When I run swupd commands manually they successfully use the proxy and are able to reach cdn.download.clearlinux.org
When swupd-update.service is called by swupd-update.timer, the task fails with the error
Error: Curl - Communicating with server timed out
Error: Failed to connect to update server: https://cdn.download.clearlinux.org/update/version/format30/latest
The systems do not use autoproxy, but instead have manual proxy configuration setup according to https://docs.01.org/clearlinux/latest/guides/network/proxy.html
It seems that the swupd-update.service is failing to import the proxy settings from /etc/profile.d/
I have just verified this by modifying the swupd-update.service unit file to explicitly define the proxy. With Environment=https_proxy=http:// added to the unit file the service works.
What is the proper way to configure swupd-update.service to use a proxy in an environment with no autoproxy?
