How do I fix: error: querying path in database: database disk image is malformed
--------------------------------------------------------------------------------
No known solution yet.
Try:
sqlite3 /nix/var/nix/db/db.sqlite "pragma integrity_check"
Which will print the errors in the database. If the errors are due to missing
references, the following may work:
mv /nix/var/nix/db/db.sqlite /nix/var/nix/db/db.sqlite-bkp
sqlite3 /nix/var/nix/db/db.sqlite-bkp ".dump" | sqlite3 /nix/var/nix/db/db.sqlite
