Git installation canceled

Error message

Git installation canceled

What it means

InstallGitIfNecessary loops while git is not installed: it shows a dialog asking to install git. If the user closes/dismisses the dialog (result None) the method throws OperationCanceledException('Git installation canceled') to abort the surrounding package install, since git is required to clone/update packages.

Solutions

1. Install git system-wide (e.g. sudo apt install git / dnf install git) and re-run the package install.
2. If the dialog appears again, choose to install git rather than canceling.
3. Dismissal is intentional cancellation — retry the operation and accept the prompt to proceed.

if (!await helper.CheckIsGitInstalled())
    return; // skip git-dependent install or pre-install git

try { await helper.InstallGitIfNecessary(); }
catch (OperationCanceledException ex) when (ex.Message == "Git installation canceled")
{ logger.Info("User declined git install; aborting package install gracefully."); }

When it happens

Trigger: Installing/updating a package on Linux when git is not on PATH, and the user clicks 'Cancel'/closes the ContentDialog instead of installing git.

Common situations: Fresh Linux install without git present; user declines the prompted installation and the package install aborts; first-run package setup on minimal distros.
