If you are seeing the error message "Couldn't retrieve directory information" in Kodi 17, it can be due to several reasons. Here are some steps you can try to fix the issue:
1. Check your internet connection: This error can occur when Kodi is unable to connect to the internet. Ensure that your device is connected to a stable and fast internet connection.
2. Check the source URL: If the source URL of the add-on you are trying to install is incorrect, Kodi may not be able to retrieve directory information. Double-check the URL and make sure it's correct.
3. Clear Kodi cache: Clearing Kodi's cache may help fix this issue. Go to "Settings" > "File Manager" > "Profile directory" > "Database" and delete the file "Addons27.db". Then restart Kodi and try accessing the add-on again.
4. Check for updates: An outdated version of Kodi may cause this error. Make sure you are running the latest version of Kodi by going to "Settings" > "System" > "System info" and checking for updates.
5. Use a different repository: If the repository you are using is down or not functioning properly, you may receive this error. Try installing the add-on from a different repository.
6. Disable any VPN or firewall: If you have a VPN or firewall enabled, it may be blocking Kodi from accessing the internet. Try disabling them and see if the issue is resolved.
7. Check for regional restrictions: Some add-ons may be restricted in certain regions. If you are trying to access an add-on that is restricted in your region, you may receive this error.
If none of these steps work, it may be best to seek help from the Kodi community or the developer of the add-on you are trying to install.
