sync_environment.py - Problems with Python 3.11 ?

[umrubi1]

Hi,

we are fequently using the provided scripts (thanks for your work and sharing) but it seems to be, that the sync_environment.py or smtools.py has problems with newer than Python 3.6. In our environment, we have three systems (details below) and it is only working on SLE as expected (like the last years). The systems with Uyuni and openSUSE are showing this behavior, because they are newer regarding their versions.

Information's

System 1 (Uyuni)

OS: openSUSE Leap Micro 6.1 / 6.4.0-28-default
Arch : x86_64
Uyuni-Server-release: 2024.12 (2024.12-241000.225.1.uyuni5)
Python-Version: 3.11.8

System 2 (Uyuni)

OS: openSUSE Leap Micro 6.1 / 6.4.0-30-default
Arch : x86_64
Uyuni-Server-release: 2025.05 (2025.05-241000.230.3.uyuni5)
Python-Version: Python 3.11.12

System 3 (SUMA)

OS: SLE Micro / 5.14.21-150500.55.100-default
Arch : x86_64
SUMA-Server-release: 5.0.4 
Python-Version: Python Python 3.6.15

Problem

The process starts, find the first project with environment "monthly" and triggers the build. In UI, it can be seen, that the channels will be updated.
Then, the script tries to check the current progress status, then the error occurs and it crash.

Output

Current workaround

We have to press the button in our projects manually. :-/

Unfortunately I am not so familiar with python but maybe some can give me a hint to fix this.

Thanks in advance and regards

could you point from where the python script is coming from, I was unable to find it on our codebase.

[umrubi1]

Hello, thanks for the fast reaction and of course... they are located in the uyuni-tools folder

• smtools.py
• sync_environment.py

[rjmateus]

From the last message in the logs looks it could be related to SSL verification: ssl.SSLEOFError: EOF occurred in violation of protocol

[umrubi1]

Yes, seems to be the issue. I have seen, that other scripts like (do_package_update.py) are showing similar/same issues but they do not crash like the mentioned script. I guess, it is related to smtools.py.

There is a configsm.yaml which holds the settings for the server. Since the beginning of using it, we have the server in FQDN configured there. The certificate and the credentials are still valid (checked today).

openssl s_client -showcerts -servername uyuni-server1.myfqdn -connect uyuni-server1.myfqdn:443 | openssl x509 -noout -dates | grep '^notAfter'

The code has not yet been optimized/checked on python3.11.

I will have a hackweek project to or run it in a container or create a venv environment.

Hello

thanks for the updated files. It now working for us.
