Obs Management

OBS Management

Manage packages in the Open Build Service for home:aspiers.

When to Use This Skill

Use this skill when:

• Working with OBS packages at /home/adam/OBS/home/aspiers
• Creating new OBS packages
• Building, testing, or debugging OBS packages
• Managing package sources, patches, andspec files

CRITICAL REQUIREMENT: BUILD FROM SOURCE ONLY

NEVER use pre-built binaries, AppImages, or binary packages in OBS!

The entire purpose and requirement of OBS is to build packages from source code. This ensures:

• Reproducible builds
• Security and transparency
• Distribution-specific optimizations
• License compliance verification

Always download source tarballs, not binary releases. If a package fails to build from source, debug and fix the build process - do NOT look for pre-built alternatives.

Setup and Basic Commands

Create a new package

read -p "Package name: " PKG_NAME
read -p "Source URL (tarball, git repo, etc.): " SOURCE_URL
cd /home/adam/OBS/home/aspiers
osc mkpac "$PKG_NAME"
cd "$PKG_NAME"
echo "Package $PKG_NAME created. Source: $SOURCE_URL"
echo "Next steps: download source, create .spec file, add files with 'osc add'"

Common workflow for existing packages

cd /home/adam/OBS/home/aspiers/<package-name>
osc up                   # Update from OBS
osc status               # Check local changes
osc add <new-files>      # Add new files
osc commit -m "message"  # Commit changes

Building and Testing

Build locally (takes 1-2+ minutes)

osc build openSUSE_Tumbleweed x86_64      # Build for Tumbleweed
osc build --clean                         # Clean build

Monitor remote build results

osc results                               # Show build status for all targets
osc results openSUSE_Tumbleweed           # Show results for specific target
osc results --watch                       # Watch results continuously

Check build logs

osc bl openSUSE_Tumbleweed x86_64         # View build log
osc blt openSUSE_Tumbleweed x86_64        # Tail build log (follow)
osc bl --last openSUSE_Tumbleweed x86_64  # Last failed build log

Using _service for automatic source updates

<services>
  <service name="tar_scm" mode="disabled">
    <param name="url">http://git.savannah.gnu.org/r/devilspie2.git</param>
    <param name="scm">git</param>
    <param name="version">0.39</param>
    <param name="revision">v0.39</param>
  </service>
  <service name="recompress" mode="disabled">
    <param name="file">devilspie2-*.tar</param>
    <param name="compression">bz2</param>

Troubleshooting

Common issues

Useful debugging

osc chroot openSUSE_Tumbleweed x86_64   # Enter build chroot
osc shell openSUSE_Tumbleweed x86_64    # Interactive shell in build env
osc log <package-name>                  # View commit history

Important Notes

• Reproducibility is essential: files added via osc add must have a clear origin
• Always test builds locally before committing to OBS!
