Error: "Cannot install plugin of type "

Exact same happening here. Just that with another plugin: swftools

The problem is that this module does not exist or does not have D6 compatibility listet at this list:

http://updates.drupal.org/release-history/project-list/all

Plugin Manager does only install modules listed there. So, this is not directly a problem of plugin_manager.

However, plugin_manager should do a better check to see if there is actually a matching row in the database and deny the installation of this module from the beginning.

I think the problem is with the way plugin_manager stores plugin types. Could you inspect your msql database?
look in the table "plugin_manager_taxonomy", where short_name is "views" (or whatever).

Did yo actually load the database with admin/plugin_manager/reload atleast once ?

same issue here, I think it's a critical bug. :(
I'll deep into the source code as soon as possible.

Since {plugin_manager_taxonomy} is empty, I replaced the $row = db_fetch_array( ... ) line with $row['tag'] = 'modules';, tried to update the feedapi_mapper module and it said "Successfully installed feedapi_mapper".

In fact, however, it doesn't seem the module has been updated.

In the ftp_plugin_manager_copy_library() function, in ftp.backend.inc file, I simply added a '/' to the beginning of $ftp_path when plugin_manager is guessing the chrooted path:

  // Try to guess which how far in we are chrooted...
  if (empty($ftp_path)) {
    foreach ($local_path AS $index => $value) {
      unset($local_path[$index]);
      if (ftp_nlist($connect, implode('/', $local_path) .'/'. $dir)) {
        $ftp_path = '/' . implode('/', $local_path) .'/'. $dir;           // notice it has been added an initial '/'
        ...

and it's working now: it has correctly updated views, panels and several other modules to their lastest version.

Then, it seems it's a path issue.
Please check it, and sumbit a better solution than mine. ;)

@Antinoo
if that fixed it, weren't you getting an error before about 'Could not guess the ftp directory for drupal.'?

@nbz: are you still getting those errors (and have you updated to the latest CVS version)?

so all other modules install fine?

--yes the CVS version (and the dev version) are more updated than the latest "stable" version.

@jabapyth: no, it was not giving me that error.

just for your information, my Drupal installation is at /public_html/.
Without the initial '/', I think plugin_manager was trying to create public_html/sites/all/modules/views/.
Since Drupal index.php is at /public_html/, this maybe means that plugin_manager was trying to create /public_html/public_html/sites/all/modules/views/.
And this resulted in an error (suppressed by the use of @ when calling ftp_mkdir()).

Hope this helps.

strange -- that shoudn't have failed..... (even though it was wrong)

I second this. This seems as a good solution.

I am getting this error on a fresh install of Drupal 6.15, using Plugin Manager 6.x-1.10, when I try to install FCKeditor 6.x-1.4.

Happy to help if you let me know what more information you need.

I get the exact same error reported by ozish after trying to install the latest update of FCKEditor module.

Cannot install plugin of type
Unable to install fckeditor

Now the plugin manager is pretty much unusable because FCKEditor doesn't show up in the module options, but does show up where I can pick the version. This seems to be a bug. See attached screenshots.
