[Nix-dev] error: querying path in database: database disk image is malformed

[Marco Maggesi]

Hi,

during the last upgrade I got this error:

# nix-env --always -u
error: querying path in database: database disk image is malformed
(use ‘--show-trace’ to show detailed location information)

Here is what sqlite says:

./sqlite3 /nix/var/nix/db/db.sqlite "pragma integrity_check"
*** in database main ***
Page 5033: btreeInitPage() returns error code 11
Page 3988: btreeInitPage() returns error code 11
Page 1926: btreeInitPage() returns error code 11
Page 2363: btreeInitPage() returns error code 11
Page 3146: btreeInitPage() returns error code 11
Page 5090: btreeInitPage() returns error code 11
Page 5124: btreeInitPage() returns error code 11
Page 283: btreeInitPage() returns error code 11
Error: database disk image is malformed

Can you give me a suggestion on the cheapest way to recover from this?

Thanks,
Marco
