$ sudo dnf install -y epel-release --skip-broken
Installing:
 epel-release          noarch          9-7.el9            extras           19 k
Complete!

Result: EPEL installed successfully (19 kB package) without triggering updates.

5. Pip Bootstrap Installation ✅

$ curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py && python3 get-pip.py --user
Successfully installed pip-25.3 wheel-0.45.1

Result: Pip installed in user space without requiring system packages.

6. Waldur Site Agent Installation ✅

$ python3 -m pip install --user waldur-site-agent
Successfully installed waldur-site-agent-0.7.8 waldur-api-client-7.8.5
# ... + 21 additional dependencies

Installation details:

23 packages resolved and installed
waldur-site-agent: 0.7.8 (same version as Ubuntu)
Python 3.9 compatibility confirmed
No compilation issues despite lack of development tools

7. Agent Functionality Verification ✅

$ ~/.local/bin/waldur_site_agent --help
usage: waldur_site_agent [-h]
         [--mode {order_process,report,membership_sync,event_process}]
         [--config-file CONFIG_FILE_PATH]

All commands available:

✅ waldur_site_agent
✅ waldur_site_diagnostics
✅ waldur_site_load_components
✅ waldur_site_create_homedirs
✅ waldur_sync_offering_users
✅ waldur_sync_resource_limits

8. Service User Setup ✅

$ sudo useradd -r -s /bin/bash -d /opt/waldur-agent -m waldur-agent
# User created successfully

$ sudo -u waldur-agent pip install waldur-site-agent
Successfully installed [all packages]

Result: Service user installation completed successfully with isolated environment.

9. Service User Agent Testing ✅

$ sudo -u waldur-agent /opt/waldur-agent/.local/bin/waldur_site_agent --help
# Full help output displayed

Result: Agent fully functional for service user with correct binary path.
