Plugin install error: Installation failed: The package could not be installed

The install problem appears to be an error in how I put files in my Subversion repository. If the files are not in the right place, then the WP plugin install doesn’t find them.

My current understanding is that the files belong here

  • trunk – the zip and extracted current versions

  • tag – create a subfolder here for the version number, place zip
    and extracted of current version in same-numbered version folder

  • (root) – the current zip and extracted files

Once I put the files in the proper place, the plugin would install via the Add Plugin screen.
