skype: error while loading shared libraries: libXss.so.1: cannot open shared object file: No such file or directory

Solution 1:

Looks like you're missing a library file. The program apt-file can be used to find which package provides a certain file. (dpkg -S does this too, but does not work for packages which are not installed)

apt-file search libXss.so yields:

ia32-libs: /usr/lib32/libXss.so
ia32-libs: /usr/lib32/libXss.so.1
ia32-libs: /usr/lib32/libXss.so.1.0.0
libxss-dev: /usr/lib/libXss.so
libxss1: /usr/lib/libXss.so.1
libxss1: /usr/lib/libXss.so.1.0.0
libxss1-dbg: /usr/lib/debug/usr/lib/libXss.so.1.0.0

You need to install the libxss1 package for that library. If you're running the 32-bit version of Skype, ia32-libs needs to be installed instead of libxss1.

Solution 2:

worked for me:

echo foreign-architecture i386 | sudo tee /etc/dpkg/dpkg.cfg.d/multiarch
sudo apt-get install libxss1:i386 libqtcore4:i386 libqt4-dbus:i386
sudo apt-get install libqtgui4:i386

got from: https://bugs.launchpad.net/ubuntu/+source/ia32-libs/+bug/830440

Solution 3:

For later 64 bit Ubuntu versions

$ locate libXss.so.1
/usr/lib/x86_64-linux-gnu/libXss.so.1
/usr/lib/x86_64-linux-gnu/libXss.so.1.0.0
$ dpkg -S libXss.so.1
libxss1:amd64: /usr/lib/x86_64-linux-gnu/libXss.so.1.0.0
libxss1:amd64: /usr/lib/x86_64-linux-gnu/libXss.so.1

So you have to install a 32 bit version of libxss1 library file (ie,libxss1:i386) because there isn't a 64 bit version of skype. 32 bit Skype must need a 32 bit library file. So installing 32 bit version of libxss1 package will solves your problem.

sudo dpkg --add-architecture i386
sudo apt-get install libxss1:i386
