Here is the file named test

The following packages have unmet dependencies:

libqt4-core : Depends: libqt4-dbus (= 4:4.8.2+dfsg-10) but
4:4.8.2+dfsg-2 is to be installed
Depends: libqt4-network (= 4:4.8.2+dfsg-10) but 4:4.8.2+dfsg-2 is to be installed
Depends: libqt4-script (= 4:4.8.2+dfsg-10) but it is not going to be installed
Depends: libqt4-test (= 4:4.8.2+dfsg-10) but it is not going to be installed
Depends: libqt4-xml (= 4:4.8.2+dfsg-10) but 4:4.8.2+dfsg-2 is to be installed

    Assuming there is some sort of formatting glitch at:

    Depends: libqtcore4 (= 4:4.8.2+dfsg-10) but 4:4.8.2+dfsg-2 is to be installed libqt4-gui : Depends: libqt4-designer (= 4:4.8.2+dfsg-10) but it is not going to be installed

    (so in fact it probably reads:

    Depends: libqtcore4 (= 4:4.8.2+dfsg-10) but 4:4.8.2+dfsg-2 is to be installed
libqt4-gui : Depends: libqt4-designer (= 4:4.8.2+dfsg-10) but it is not going to be installed

    ) then this should do:

    sed 's/.*Depends: \([^ ]*\) .*/\1/' lib-dep-list

    Given data file lib-dep-list:

    libqt4-core : Depends: libqt4-dbus (= 4:4.8.2+dfsg-10) but 4:4.8.2+dfsg-2 is to be installed
Depends: libqt4-network (= 4:4.8.2+dfsg-10) but 4:4.8.2+dfsg-2 is to be installed
Depends: libqt4-script (= 4:4.8.2+dfsg-10) but it is not going to be installed
Depends: libqt4-test (= 4:4.8.2+dfsg-10) but it is not going to be installed
Depends: libqt4-xml (= 4:4.8.2+dfsg-10) but 4:4.8.2+dfsg-2 is to be installed
Depends: libqtcore4 (= 4:4.8.2+dfsg-10) but 4:4.8.2+dfsg-2 is to be installed
libqt4-gui : Depends: libqt4-designer (= 4:4.8.2+dfsg-10) but it is not going to be installed
Depends: libqt4-opengl (= 4:4.8.2+dfsg-10) but 4:4.8.2+dfsg-2 is to be installed
Depends: libqt4-svg (= 4:4.8.2+dfsg-10) but it is not going to be installed
Depends: libqtgui4 (= 4:4.8.2+dfsg-10) but 4:4.8.2+dfsg-2 is to be installed

    The output is:

    libqt4-dbus
libqt4-network
libqt4-script
libqt4-test
libqt4-xml
libqtcore4
libqt4-designer
libqt4-opengl
libqt4-svg
libqtgui4
