How do i check for dependencies for an ubuntu package?

shoebill

To show what package depends on and replaces run the following command. These are the package needed before the package you are installing can be installed.

$ apt-cache depends tcpdump
tcpdump
  Depends: libc6
  Depends: libpcap0.8
  Depends: libssl1.1
  Breaks: apparmor-profiles-extra
  Suggests: apparmor
  Replaces: apparmor-profiles-extra
