## Problem
|
|
GUI updater (dnf/PackageKit) hanging on Nobara 43 (Fedora 43 based) during system updates.
|
|
|
|
## Root Causes Identified
|
|
1. **Python version conflict**: System had both Python 3.13 and 3.14 packages installed, preventing upgrade resolution
|
|
- Solution: Removed python3.13, python3.13-libs, python3.13-tkinter packages
|
|
|
|
2. **x264-libs repository exclusion**: RPM Fusion repos had x264-libs excluded (Nobara-specific config)
|
|
- x264-libs needed upgrade from 1.164 (fc42) to 0.165 (fc43)
|
|
- Solution: Used 'dnf swap' to force install x264-libs-0.165 from nobara-pikaos-additional repo
|
|
|
|
3. **/boot/efi partition full**: 96MB partition at 100% capacity
|
|
- Old kernel EFI file (52MB) from 6.12.9-200.fsync.fc41 in /boot/efi/EFI/Linux/
|
|
- Solution: Removed old kernel EFI file, freed 52MB (now at 47% usage)
|
|
|
|
## Commands Used
|
|
```bash
|
|
# Clean DNF cache
|
|
sudo dnf clean all
|
|
|
|
# Remove Python 3.13 versioned packages
|
|
sudo dnf remove -y python3.13 python3.13-libs python3.13-tkinter
|
|
|
|
# Force x264-libs upgrade (swap old for new)
|
|
sudo dnf swap -y x264-libs-1.164 x264-libs-0.165 --allowerasing
|
|
|
|
# Remove old kernel EFI file
|
|
sudo rm /boot/efi/EFI/Linux/cba6e2cdd7ae4f0f8907c42ff6dd971f-6.12.9-200.fsync.fc41.x86_64.efi
|
|
|
|
# Run system upgrade
|
|
sudo dnf upgrade -y
|
|
|
|
# Clean up unused packages
|
|
sudo dnf autoremove -y
|
|
```
|
|
|
|
## Results
|
|
- Successfully updated 3,217 packages
|
|
- Freed 562MB of disk space from autoremove
|
|
- EFI partition now at 47% usage (52MB free)
|
|
- New kernel 6.18.7-200.nobara.fc43 installed
|
|
|
|
## Post-Reboot Steps
|
|
1. System currently running kernel 6.15.5-200.nobara.fc42
|
|
2. After reboot, will boot into 6.18.7-200.nobara.fc43
|
|
3. Can remove old kernel 6.15.4: `sudo dnf remove kernel-6.15.4-200.nobara.fc42`
|
|
|
|
## Key Learnings
|
|
- Nobara excludes certain packages (x264-libs, ffmpeg, etc.) from RPM Fusion repos via /etc/yum.repos.d/*.repo exclude lists
|
|
- These excluded packages come from nobara-pikaos-additional repo instead
|
|
- Small EFI partitions (96MB) can fill quickly with unified kernel images (UKI files)
|
|
- Python versioned packages (python3.X) can conflict with main python3 package during distro upgrades
