Dpkg

dpkg is Debian's default packaging software. However you will normally use apt-get to install Debian software. Here are package management issues and how you achieve them using dpkg or rpm.

Issue	rpm	dpkg
how files are called	*.rpm	*.deb
list all installed packages	rpm -qa	dpkg -l
list all installed packages by order of installation date	rpm -qa --last
install a package from a file	rpm -i file.rpm	dpkg -i file.deb
list package content	rpm -ql package	dpkg -L package
find what package provides the installed file /bin/ls	rpm -qf /bin/ls	dpkg --search /bin/ls
look at a package file description		dpkg -I file.deb
look at a package description	rpm -qi package	apt-cache show package
find which installed package provides /bin/bash	rpm -qf /bin/bash	dpkg -S /bin/bash (to also search in not installed packages you can use apt-file)
find what program provides the file Xlib.h		auto-apt search Xlib.h
extract a package	rpm2cpio blah.rpm | cpio -id	dpkg -x datei.deb target_folder
remove a package, but do not run pre-uninstall scripts before	rpm -e --nopreun xyz	rm /var/lib/dpkg/info/xyz.prerm; dpkg -r xyz

TroubleShooting

Example problem

root@lvps83-169-3-117:~# apt-get install kde
Reading package lists... Done
Building dependency tree
Reading state information... Done
You might want to run `apt-get -f install' to correct these:
The following packages have unmet dependencies:
  kde: Depends: kde-core (>= 5:47) but it is not going to be installed
       Depends: kde-amusements (>= 5:47) but it is not going to be installed
       Depends: kdeaccessibility (>= 4:3.4.3) but it is not going to be installed
       Depends: kdeaddons (>= 4:3.4.3) but it is not going to be installed
       Depends: kdeadmin (>= 4:3.4.3) but it is not going to be installed
       Depends: kdeartwork (>= 4:3.4.3) but it is not going to be installed
       Depends: kdegraphics (>= 4:3.4.3) but it is not going to be installed
       Depends: kdemultimedia (>= 4:3.4.3) but it is not going to be installed
       Depends: kdenetwork (>= 4:3.4.3) but it is not going to be installed
       Depends: kdepim (>= 4:3.4.3) but it is not going to be installed
       Depends: kdeutils (>= 4:3.4.3) but it is not going to be installed
       Depends: kdewebdev (>= 4:3.4.3) but it is not going to be installed
  psa: Depends: libpam-plesk but it is not going to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).

Once solution was to remove a postuninstall script, /var/lib/dpkg/info/psa-imp.postrm
