How to install Qucs in Ubuntu
To install Qucs in Ubuntu
Quite Universal Circuit Simulator (Qucs) is a free-source electronics circuit simulator software. It is used to create a circuit with a graphical user interface. It replicates the large-signal, small-signal and noise behavior of the circuits. Installation of Qucs is explained in this manual.
To install Qucs
First add repository to your apt source by using “ add-apt-repository” command.
root@linuxhelp:~# add-apt-repository ppa:fransschreuder1/qucs
This is the official PPA qucs (http://qucs.sourceforge.net), until ubuntu will take qucs back in their repository.
The reason why qucs was out of the ubuntu repository is that it was still using qt3 which was removed from ubuntu 12.10 as well.

It would be very useful to start with a date, then the versions of Ubuntu and Qucs that you are using. At this point it appears the repository version is broken, and builds are only available for previous Ubuntu versions. Even after building from the source it doesn't work.
No matter how good your info is, it will eventually go out of date, but without that date there, nobody will know.

A
Please contact the developers. Provide details and if available a crash report.
Q
What kind of software is need to be installed on my system to run Qucs?
A
Currently, Qt4 (version 4.6 and higher) are known to work well. To compile guess you will need some additional packages like qt4-dev-tools, bison, flex, gperf, and adms-2.3.0 (included into Qucs)
Q
How can I set the language for Qucs?
A
If you want to change the language for the Qucs GUI you need to quit Qucs and then
$ export LANG=de
for German for example. Then start Qucs again. Also, you can change the language in the application settings dialog
