Since installing mopidy in Ubuntu 24.04.2, the database seems to lock up after a few searches, getting stuck in a loop

```

I only have local files and this issue is not limited to Punk and it is not systematic. I never saw this issue with Ubuntu 20 so I was wondering if there might be a connection. To break the loop, I restart mopidy, but it takes a good 5 mins to get the terminal back.  
Any thoughts are most welcome.

Can you try clearing out your database and doing a fresh scan?

I can’t find anything on how to “clear out” the database. To be honest, I don’t know where the database is held. Could you tell me please?

Please find the documention for Mopidy-Local on github: [GitHub - mopidy/mopidy-local: Mopidy extension for playing music from your local music archive](https://github.com/mopidy/mopidy-local?tab=readme-ov-file#clearing-the-library)

Keep in mind that when running as a service you’ll need to use `sudo mopidyctl` rather than `mopidy`.

```auto
sudo mopidyctl local clear

```

is a good one to know.  
It has speeded up my searches and for the moment I am no longer getting the above error. Thank you

Not sure what’s going on with that truncated log message, can’t tell much from that. Could you increase the log verbosity?

## Disclaimer - what I write below as to how I solved this issue is only an impression of how I troubleshot the issue .

The issue seems to have been linked to extensions that I had installed to test and that seem not to have been deactivating as per the numerous conf files that are installed.  
I set installed My setup to use systemctl and not local. This seems to be a very, very important choice when it comes to extensions. On my Ubuntu, I have python3 installed for the OS. From what I understand, mopidy systemctl uses this python3 installation to run across all users. The alternative is a local python3 installation that runs only with the specified user logged in. I think this explains why there are so many conf files which all have different setups.  
n short, I deduce that , if you start mopidy locally, mopidy will refer to the local confs and in systemctl, it refers to anything it finds across the machine.  
Also, I deduce that mopidy automatically manages installed extensions which may not have conf info. This is important as my mopidy conf was showing extension confs that did not exist in any of the conf files I could find. Therefore, mopidy was running a few of services on its own that seem to have been grinding mopidy to a halt (particularly constant internetarchive, YT, radio and podcast scans.)  
Currently, I don’t understand how to manage extensions from  
[https://mopidy.com/ext/](https://mopidy.com/ext/)  
for the systemctl. I install the extensions directly into the OS python3 install getting this advice.  
``admin@ubservlow:/usr/bin$ sudo python3 -m pip install Mopidy-Bandcamp  
error: externally-managed-environment

× This environment is externally managed  
╰─\> To install Python packages system-wide, try apt install  
python3-xyz, where xyz is the package you are trying to  
install.

```
If you wish to install a non-Debian-packaged Python package,
create a virtual environment using python3 -m venv path/to/venv.
Then use path/to/venv/bin/python and path/to/venv/bin/pip. Make
sure you have python3-full installed.

If you wish to install a non-Debian packaged Python application,
it may be easiest to use pipx install xyz, which will manage a
virtual environment for you. Make sure you have pipx installed.

See /usr/share/doc/python3.12/README.venv for more information.

```

note: If you believe this is a mistake, please contact your Python installation or OS distribution provider. You can override this, at the risk of breaking your Python installation or OS, by passing --break-system-packages.  
hint: See PEP 668 for the detailed specification.  
``

I have to use

```auto
sudo python3 -m pip install Mopidy-Bandcamp --break-system-packages

```

which works. (I presume this is very bad practice, but I don’t understand what the systemctl alternative is.)

The problem seems to have been that I had lots of extensions installed that were running without a written conf file reference or were not activating properly.  
My mopidy had become a mess.  
I uninstalled all the deps and mopidy and then had to reinstalled the essential extensions. I cleaned out all the conf files and created only the confs that correspond to the installed extensions.  
Managing extensions is a mystery to me above all when they can be installed system wide and in the locally. I don’t understand how I deleted the extensions from the system and I could find much in the doc about how to managed them completely (as I still don’t understand where they are installed.)  
I hope this helps someone.
