Bug#933353: liblapack3: ldconfig not run after install

[Jochen Topf]

Package: liblapack3
Version: 3.8.0-2
Severity: normal

Dear Maintainer,

Fresh install of Buster. Installed "osmcoastline" which depends on
liblapack3 which was installed automatically. But when I tried to run it
this error was displayed:

osmcoastline: error while loading shared libraries: liblapack.so.3:
cannot open shared object file: No such file or directory

Running ldconfig manually fixed the problem.

Might be due to the '-n' here:
