Well, I've had some baffling issues with PPAs, so I'm probably not the best to address this. But here's a checklist of things you might try:
When using aptitude, if you see a package listed as "(Unsatisfied)" after attempting to install it, this indicates that the package has unmet dependencies or that one or more of its required dependencies could not be installed or resolved. This situation is commonly referred to as an "unmet dependency" error.
Causes of "(Unsatisfied)" Status
Missing Dependencies: The package you tried to install requires other packages that are not available in your repositories or cannot be installed due to version conflicts.
Broken or Held Packages: Some packages on your system may be held at specific versions or are broken, preventing the installation or upgrade of dependencies needed by the new package.
Repository Issues: If your software sources (repositories) are outdated, misconfigured, or missing, required packages may not be found, leading to unsatisfied dependencies.
Mixing Releases or PPAs: Installing packages from different distributions or third-party repositories can result in dependency mismatches, making it impossible to satisfy all requirements.
How to Diagnose and Fix
Check Dependency Details: Use aptitude's interactive mode or the command line to review which dependencies are unsatisfied. Try running:
sudo aptitude install package-name
aptitude will often suggest solutions or highlight which dependencies are missing or conflicting.
Try to Install Dependencies Manually: Attempt to install the dependencies individually to see which one is causing the issue. This can help pinpoint the root cause.
Fix Broken Packages: Use the following commands to attempt to fix broken dependencies:
sudo apt-get install -f
sudo dpkg --configure -a
These commands try to fix broken installs and configure any unpacked but unconfigured packages.
Update Repositories: Ensure your package lists are up to date:
sudo apt-get update
If necessary, check your /etc/apt/sources.list for correctness.
Clear Package Cache: Sometimes, cleaning the cache can help resolve issues:
sudo apt-get clean
sudo apt-get autoclean
This removes old or corrupt package files that might be interfering with installations.
If you continue to see "(Unsatisfied)" after trying these solutions, review the specific error messages provided by aptitude for more details on which dependencies are causing the problem and consider seeking help with those specific packages.
