What does Ubuntu software center error "bad quality package " means? [duplicate]

Solution 1:

You can see why a particular package is considered a bad quality by looking at the details provided in that dialog box. It usually has to deal with how a package is packaged and not the package itself.

If the package doesn't meet the Debian policy, then it is considered to be of a poor quality.

Some common issues that trigger this warning are:

• The package has some file ownership errors
• There is no valid "Installed-size" field in the control file, etc.

Solution 2:

The meaning can vary from deb to deb, it basically means something is missing / not packaged 100% right.

You can install it either using dpkg:

Assuming you've downloaded the .deb in your ~/Downloads folder, run the following commands in a terminal to install all the .deb files:

cd ~/Downloads
sudo dpkg -i *.deb
sudo apt-get install -f

Or use Gdebi. Install Gdebi first:

sudo apt-get install gdebi gdebi-core

You can then right click a .deb file and select "Open with Gdebi Package Installer".
