** Summary changed:
- python3-docker `from_env()` broken
+ [SRU] python3-docker `from_env()` broken
** Description changed:
- I have a python script that manages some docker resources. It uses the
- `from_env()` method to build the client. This script always runs as
- root.
+ [ Impact ]
- This worked in Ubuntu 22.04. However, it seems like something is
- mismatched in 24.04, as I now get the following error, even after a
- reboot (which seemed to solve this for others in the past?). It appears
- based on cursory googling that a library version might be out of sync.
+ python3-docker is completely unusable. It will fail immediately when the
+ user tries to use it after importing the module.

+
+ [ Test Plan ]
+
+ Install python3-docker and docker.io
+ In the python3 prompt, use the following commands to test:
+
+ >>> import docker
+ >>> client = docker.from_env()
+ >>> client.containers.run("ubuntu:latest", "echo hello world")
+
+ With the fixed package it will print:
+ b'hello world\n'
+
+ Note: the test expects the user is part of docker group. If not, then
+ use "sudo python3" to get to the python prompt.
+
+ [ Where problems could occur ]
+
+ The upstream patch is using urllib3 and is changing the way it makes the
+ network connections. The testplan is only testing one usecase. So there
+ might be a chance that other types of connections are not working after
+ this change. But considering the fact the python3-docker is unusable
+ now, the user should not see any new regression than what already
+ exists.
+
+
+ [ Other Info ]
+
+ 1. This has been fixed in Debian and so Oracular is also fixed.
+ 2. A new runtime dependency on python3-urllib3 has been added as is done in
Debian.

This is on a fresh 24.04 install.
Willing to help diagnose, but to replicate:
- 1. `apt install docker.io python3-docker`
- 2. `python3`
- 3. `import docker`
- 4. `docker.from_env()`
+ 1. `apt install docker.io python3-docker`
+ 2. `python3`
+ 3. `import docker`
+ 4. `docker.from_env()`
