The impression given by the FHS is that, upon deletion, the system
should be able to recreate anything in a cache directory. I suspect
that running something like apt-get update might do it. (It's not
always clear exactly whose responsibility such recreation is.)
5.5. /var/cache : Application cache data
5.5.1. Purpose
/var/cache is intended for cached data from applications. Such
data is locally generated as a result of time-consuming I/O or
calculation. The application must be able to regenerate or
restore the data. Unlike /var/spool, the cached files can be
deleted without data loss. The data must remain valid between
invocations of the application and rebooting the system.
Files located under /var/cache may be expired in an application
specific manner, by the system administrator, or both. The
application must always be able to recover from manual deletion
of these files (generally because of a disk space shortage). No
other requirements are made on the data format of the cache
directories.
