Ubuntu – Does Software Center report qt4 as unmet dependency, when I already have qt5 installed

dependenciesqtqt5

I installed qtspim which requires qt4 to be installed. As I already have qt5 installed on my system, qtspim is working fine.

However, Software Center reports dependency error. When I run apt-get check it gives:

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:
 qtspim : Depends: qt4-dev-tools (>= 4.7) but it is not installed
      Depends: qt4-doc (>= 4.7) but it is not installed
E: Unmet dependencies. Try using -f.

I don't want to install qt4 as i already have the latest version installed.

Best Answer

No

you have to install qt4 libs for running qt4 programs, qt5 is not 100% backward compatable with qt4

Ubuntu – Can’t install package libglib2.0-dev because it depends on some unknown version

Try to do it with aptitude:

sudo aptitude install libglib2.0-dev

Ubuntu – Unmet dependencies (linux-headers, linux-image)

Seems like you have double sources in your plist.

To fix this issue:

sudo apt-get clean
sudo apt-get autoclean
sudo apt-get -f install

Then run :

sudo dpkg --configure -a
sudo apt-get -f install

Also you can comment out the double source in the sources.list

If you need help, print the output of the sources.list and show me.

Like this :

cat /etc/apt/sources.list > /home/user/sources.txt

If you wanne do it yourself just use nano or vim :

sudo nano /etc/apt/sources.list
