Answer 1

The name of the package is incorrect. It should be:

sudo apt-get install libpango1.0-0

Answer 2

The deb file you downloaded is from https://hadler.me/linux/forticlient-sslvpn-deb-packages/. The package maintainer there tried to build .deb files for easier installation of Forticlient–SSLVPN which comes with a .tar.gz package.

But I think, the package maintainer wrongly included libpango-1.0-0 in the dependency list in packages for releases older than 15.04. libpango-1.0-0 pulls libpango1.0-0 package in recent releases, but in 12.04 there is no libpango-1.0-0. You need to install libpango1.0-0 for that.

The easiest solution I think (I haven't tested this) to decompress and re-build the deb again. First remove the package using

sudo dpkg -P forticlient-sslvpn

Then proceed with these steps:

Install dpkg-dev package

sudo apt-get install dpkg-dev

Make a directory to extract

mkdir forticlient-sslvpn

Extract the deb file to it

dpkg-deb -R forticlient-sslvpn_4.4.2312-1_amd64.deb forticlient-sslvpn/

Go to the forticlient-sslvpn/DEBIAN folder and open control file. Change the libpango-1.0-0 in the line Depends: to libpango1.0-0. Save the file.

Return back out of the forticlient-sslvpn directory.

Use this command to build the package again.

 dpkg-deb -b forticlient-sslvpn

This should create a deb file named forticlient-sslvpn.deb. Install it with

 sudo dpkg -i forticlient-sslvpn.deb

Then install any missing dependencies using

 sudo apt-get -f install

Hope that helps.

Answer 3

Just run:

sudo apt -f install

After:

sudo dokg -i anydesk
