Pourquoi manque-t-il quelque chose à voir avec les tables sqlite?

J'ai suivi ceci: Problèmes de dépendance lors de l'installation de qgis python-qgis qgis-plugin-grass

Et en essayant d'installer:

sudo apt install libmysqlclient-dev 

Produit la même erreur à propos de qgis pour une raison quelconque.

Cela semble avoir perturbé en permanence mon système. Tout ce que j'essaie d'installer produit cette erreur.

Modifier pour le débogage

$ dpkg -S /usr/lib/libgdal.so.20
libgdal20: /usr/lib/libgdal.so.20

On dirait que votre libsqlite3 a été construite sans le commutateur:

-DSQLITE_ENABLE_COLUMN_METADATA

ce que libgda1.so.20 attend.
