Bug#852151: error: cannot open Packages index using db5 - Input/output error (5)

[積丹尼 Dan Jacobson]

Loading new nvidia-legacy-304xx-304.134 DKMS files...
error: db5 error(5) from dbenv->open: Input/output error
error: cannot open Packages index using db5 - Input/output error (5)
error: cannot open Packages database in /root/.rpmdb

Which goes on for at least four screens!

Maybe related, but I don't see why I should have to mess with rpm stuff..
