# apt-key adv --keyserver keyserver.ubuntu.com --recv <keyid>
Package source which resolves to IPv6 adresses causes sometimes problems
To force the usage of the returned IPv4 adresses do:
$ echo 'Acquire::ForceIPv4 "true";' | sudo tee /etc/apt/apt.conf.d/99force-ipv4
Packages from a specific source
Prequisite: dctrl-tools
sudo apt-get install dctrl-tools
Show packages
For example all PPA packages
sudo grep-dctrl -sPackage . /var/lib/apt/lists/ppa*_Packages
From where is my package installed?
sudo apt-cache policy <package>
Does my file match the checksum from the package?
If you fear you are hacked verify your binaries!
Prequisite: debsums
sudo apt-get install debsums
Verify packages
sudo debsums <package name>
$ sudo debsums unhide.rb
/usr/bin/unhide.rb OK
/usr/share/doc/unhide.rb/changelog.Debian.gz OK
/usr/share/doc/unhide.rb/copyright OK
/usr/share/lintian/overrides/unhide.rb OK
/usr/share/man/man8/unhide.rb.8.gz OK
