If you know shortcuts for some of these things, go ahead and use them. For example, in many terminals, `cd ~/Kometa` is the same as `cd /Users/YOUR_USERNAME/Kometa`. Your Kometa installation may not be located at the paths referenced below. These are the paths used in the walkthroughs in this documentation, so if you installed it somewhere else you will have to change the path[s] to reflect your system and the choices you made during installation. ??? question "How do I update to the latest version of Kometa?" === ":fontawesome-brands-linux: Linux" [type this into your terminal, changing `YOUR_USERNAME` to your username] cd /Users/YOUR_USERNAME/Kometa git stash git stash clear git pull source kometa-venv/bin/activate python -m pip install -r requirements.txt These two commands: git stash git stash clear Will reset any changes you have made to Kometa-owned files [YOUR CONFIG FILES ARE NOT AFFECTED].

Use Kometa Caching where possible, this allows Kometa to temporarily store commonly-used information so that it can be retrieved more efficiently. There are [multiple things](https://kometa.wiki/en/latest/search.html?q=cache&check_keywords=yes&area=default) that can be cached within Kometa. Run Kometa after PLEX Scheduled Tasks, as Plex's API tends to be slower at responding whilst it is performing the tasks. By default, Kometa runs at 5AM to avoid the 3-5am window that Plex suggests for Scheduled Tasks. For users who are more technically advanced and happy to risk manipulating the Plex database, considering altering the [PRAGMA_CACHE settings](https://www.reddit.com/r/PleX/comments/ic3cjr/anyone_try_giving_sqlite3_more_cache_to_help/) within Plex. **Note:** you MUST use the version of sqlite3 tool that comes with your running version of PLEX or you will mess up your PLEX DB beyond repair. See [this article](https://support.plex.tv/articles/repair-a-corrupted-database/) on how to find the proper version for your setup. ??? question "Why does my Kometa run take so long to complete?" Every time an item (media, collection, overlay) needs to be updated, Kometa needs to send the request to Plex, and then receive confirmation back from Plex that the action has been completed. This can take anywhere from seconds to minutes depending on when Plex provides a response. Given that the typical run can update hundreds or even thousands of items, this can quickly add up to a lot of time. If "Mass Update" operations are used, then every single item in the library needs to go through this process, which can be lengthy. Overlays can be particularly cumbersome as Kometa needs to perform the following actions for each of the items that need to have an overlay applied: - Check which overlays are applicable (this will take more time depending on how many overlays you are applying) - Compare the current poster to confirm what overlays are already applied, if changes are needed then continue with the following steps - Grab source image from Plex and save it to disk - Draw each overlay image on top of the source image - save final image to disk - Tell Plex to apply new image to the item - Wait for Plex to respond confirming that the change has been made The above two points can be greatly exacerbated if Kometa has to update every episode within a Show library rather than just the Shows themselves, as there can often be hundreds of thousands of episodes to be updated with mass operations or overlays. Additionally, some collections require a lot of computing resources to determine the critera of the collections that are to be made. This is commonly seen in the Defaults files for Actor/Director/Producer/Writer which need to get the crew information for each of the movies/shows within your library, and then calculate which ones appear the most to find out which are the most popular. The larger your library, the longer this process will take. ??? question "Can I schedule library operations and/or overlays to happen at a different time than collections?" Yes, the recommended approach is to set up a new library for the Operations/Overlays, mapping it back to the original library, and then scheduling the library, as outlined below ```yaml libraries: Movie Operations: # NAME DOESN'T MATTER BUT MUST BE UNIQUE library_name: Movies # THIS MUST MATCH A LIBRARY IN PLEX schedule: weekly(monday) operations: split_duplicates: true overlay_files: - default: resolution ``` ### Errors & Issues ??? question "Why doesn't Kometa let me enter my authentication information for Trakt/MAL?" Kometa needs to run in an interactive mode which allows the user to enter information (such as the Trakt/MAL PIN) as part of the authentication process. This can prove troublesome in some environments, particularly NAS. Chazlarson has developed an online tool which will allow you to perform the authentication of both Trakt and MAL outside of Kometa, and will then provide you the completed code block to paste into your config.yml. The scripts can be found here. Click the green play button, wait a little bit, then follow the prompts. [MyAnimeList Authenticator](https://replit.com/@chazlarson/MALAuth) [Trakt Authenticator](https://replit.com/@chazlarson/TraktAuth) ??? question "Why am I seeing "(500) Internal Server Error" in my log files?" A 500 Internal Server Error happens when the server has an unexpected error when responding to an API request. There could be any number of reasons why this happens and it depends on what server Kometa is talking to although it's most likely coming from your Plex Server. Most of the time these errors need to be resolved by changing something specific to your set up but some do come up that can be fixed (i.e. Plex throws one if you upload a photo larger than 10 MB) Many Appbox Setups will throw this error when too many requests are sent, or if the central metadata repository is not properly configured to allow users to upload custom posters. Take a look at the following logs: :one: Settings | Manage | Console -> then filter on Error and Warning to see what might be going on :two: Check the plex logs (container or other) for the "Busy DB Sleeping for 200ms) There is nothing that Kometa or our support staff can really do to resolve a 500 error. ## Knowledge Base This section aims to provide some insight as to articles/information that we feel is important to document as they may pop up infrequently but often enough to require entry here. ### Kometa 1.20 Release Changes With the release of Kometa 1.20, several changes have been made. Please read the document below thoroughly! ??? blank "`metadata_path` and `overlay_path` are now legacy attributes (click to expand)."
The attributes `metadata_path` and `overlay_path` are now legacy, and will likely produce an error `metadata attribute is required` when running Kometa. We have new attributes: `collection_files`, `overlay_files` and `metadata_files` which you can read more about on the [Libraries Attributes page](../config/libraries.md#attributes) Whilst this error can be ignored, we strongly advise you to move over to the new attributes, which can be done following this guidance: :fontawesome-solid-1: If your YAML file creates collections or is a Kometa Defaults Collection File then it belongs under `collection_files`. :fontawesome-solid-2: If your YAML file creates overlays or is a Kometa Defaults Overlay File then it belongs under `overlay_files` :fontawesome-solid-3: If your YAML file edits item metadata ([see this example](../files/metadata.md/#__tabbed_1_1)) then it belongs under `metadata_files` If your file creates collections AND edits item metadata, then it should go in both `collection_files` and `metadata_files` If you are unsure on the above, the majority of `metadata_path` files will now fall under `collection_files`, and all `overlay_path` files will now fall under `overlay_files`. If you require any assistance with this, please visit our Discord Server where we can assist you. Below is an example of the new attributes in use: ```yaml libraries: Movies: collection_files: #(1)! - file: config/Movies.yml #(2)! - default: imdb #(2)! metadata_files: #(3)! - file: config/MetadataEdits.yml #(4)! overlay_files: #(5)! - file: config/Overlays.yml #(6)! - default: audio_codec #(6)! ``` 1. This attribute used to be `metadata_path` and defines files that will relate to Collections 2. These files are placed within `collection_files` because they define how Collections are built/maintained. 3. This attribute used to be `metadata_path` and defines files that will relate to Metadata Edits 4. These files are placed within `metadata_files` because they define Metadata Edits rather than collections. 5. This attribute used to be `overlay_path` and defines files that will relate to Overlays 6. These files are placed within `overlay_files` because they define how Overlays are built/maintained. ??? blank "`remove_` `reset_` `reapply_` and `schedule_` attributes for `overlays` are now Library Attributes (click to expand)."
The attributes `remove_overlays`, `reset_overlays`, `reapply_overlays` and `schedule_overlays` are now Library Attributes and are called at the library level rather than within `overlay_path`. This change has been made to make these attributes consistent with other attributes of a similar nature. Whilst the previous method still works, we strongly advise you to move over to the new attributes, which can be done by looking at the following sample YAML: ```yaml libraries: Movies: remove_overlays: false reapply_overlays: false #(1)! # reset_overlays: plex #(2)! schedule_overlays: daily overlay_files: - default: audio_codec ``` 1. We strongly advise never setting this to `true` as it can cause [Image Bloat](scripts/imagemaid.md) 2. This is purely an example, you do not need to specify `reset_overlays` or any of these attributes unless you specifically need to use them. ??? blank "`imdb_list` no longer works for Title or Keyword search URLs (click to expand)."
