SQLite snap?


I’m surprised that I cannot find a SQLite snap from the store. I noticed from a ‘sqlite’ search in the forum that there are discussions about snaps which include SQLite - so I’m assuming that SQLite is somewhere to be found as a snap. Any suggestions on how to install SQLite on Ubuntu Core?

Thank you


Those snaps which include sqlite most likely include it as part of their stage-packages; there’s no need to have a standalone sqlite snap in order to include it as part of other snaps.

I can imagine that sqlite is mostly used for specific software to manage their own internal database; its local nature means one is less likely to need a client, like one would need a, say, postgresql client to interact with an external postgresql database server.

Thanks Daniel,

The snap I would like to create, is one which reads data from a serial port, using python(3), to populate a local SQLite database. I know that python is already installed on Ubuntu Core. So, would I need to build the snap as a python app which has SQLite as a stage-package?

If so, would snapcraft build SQLite from source code (220k lines)?

Thank you


I believe there should be a python binding of the sqlite database library to add in the stage-packages. Build from source is not needed if the one provided by ubuntu packages will work.

There is indeed…

I’m very happy to report that the sqlite3 module is already pre-installed with python3 on Ubuntu Core 16 (I’m guessing this may already be well-known by many)

Does this still mean that sqlite3 should be listed as a stage-package? As well as any other module import within the python script?

Thanks again

There’s no guarantee that certain module will remain pre-installed in the future releases of the Ubuntu Core


So, a couple of things.

First and foremost, if it’s in a stable core (core and core18) and you can use it from a strict snap, it’ll continue being there. We might add things, but we’ve promised not to remove things.

Second, both core and core18's python3 installation has sqlite3 support.

Is the guarantee still hold across different core release series(e.g. core -> core 18)?
