edcuba / libdnf

Simple package manager built on top of hawkey and librepo

Hey there! 👨🏽‍💻

I'm a Software Engineer curious about AI & Machine Learning (especially GNNs, GANs, RL, and DL), Data Analysis, Cybersecurity, and Quantum Computing. I'm a BUT alumni, now at UZH, also a former Dreamer and Red Hat.

I work at CERN Openlab, exploring the overlaps of High Performance Computing, Machine Learning and Quantum Computing, and playing with Graph Neural Networks for improving particle reconstructions at the CMS Experiment.

I ❤️ Open Source!

I contributed to open-source projects in:

• RPM software management: DNF, libdnf, ci-dnf-stack
• Cyber security: Arkime, tcpflow
• AI for HPC in HEP: HEP benchmarking, Particleflow

and published a series of my own projects like Faqtie, have a look!

libdnf's Issues

[Errno 2] No such file or directory: '/var/lib/dnf/groups.json'

when running transformer script (no dnf group command was ever used so there's noo groups.json)

swdb_transformer.py

Database transformation running
Transforming packages
Transforming transactions
Transforming yumdb
Transforming groups
Traceback (most recent call last):
File "../libhif.git/python/swdb/swdb_transformer.py", line 489, in
with open(groups_path) as groups_file:
FileNotFoundError: [Errno 2] No such file or directory: '/var/lib/dnf/groups.json'

redhat-rpm-config missing

Add redhat-rpm-config to spec file

Wrong state in get_packages_by_tid

Need to fetch states from trans_data of given transaction, not the latest one...

"Performed with" missing

Transaction attribute performed with is missing in SWDB.
It should be reintroduced and used by DNF and PackageKit to identify their transactions.
