Package: lintian
Version: 2.45.0
Severity: normal

Hi,

I noticed that lintian reported a high number of packages with processing
errors on https://lintian.debian.org/.  Digging into the log, I noted the
following error:

"""
N: Starting on group cachefilesd/0.10.10-0.2
N: Unpacking packages in group cachefilesd/0.10.10-0.2
N: ----
