Epson Printer Utility not working

Question

My CPU: intel i5 64 bit processor.

Ubuntu: 18.04.1 LTS BB.

Bought a new Epson L380 inktank and down loaded the 64 bit drivers and the epson printer utility from the epson download centre website. Printing and photocopying work very well. However the epson printer utility program that is invoked from the command line using a terminal which is used to check ink levels and clean heads says:

epson-printer-utility: error while loading shared libraries: libQtCore.so.4: cannot open shared object file: No such file or directory.

Has anybody encountered this? What should I do.

Solution

I had the same problem in Ubuntu 20.04 but there were no chances to install qt4, also trying to build the file from the source code failed several times until I decided to do the following. This is not a perfect solution but in the end, it works.

The solution is to download and extract only the three missing files from qt4.

The procedure is:

Package: libqtcore4 Contains: /usr/lib/x86_64-linux-gnu/libQtCore.so.4

Download from: http://mirrors.kernel.org/ubuntu/pool/main/q/qt4-x11/libqtcore4_4.8.7+dfsg-5ubuntu2_amd64.deb

Package: libqtgui4 Contains: /usr/lib/x86_64-linux-gnu/libQtGui.so.4

Download from: http://mirrors.kernel.org/ubuntu/pool/main/q/qt4-x11/libqtgui4_4.8.7+dfsg-5ubuntu2_amd64.deb

Package: libpng12-0 Contains: /usr/lib/x86_64-linux-gnu/libpng12.so.0

Download from: http://security.ubuntu.com/ubuntu/pool/main/libp/libpng/libpng12-0_1.2.54-1ubuntu1.1_amd64.deb

Download the files to /tmp

cd /tmp

mkdir output

dpkg-deb -x libqtcore4_4.8.7+dfsg-5ubuntu2_amd64.deb output

dpkg-deb -x libqtgui4_4.8.7+dfsg-5ubuntu2_amd64.deb output

dpkg-deb -x libpng12-0_1.2.54-1ubuntu1.1_amd64.deb output

cd output

find . -name libQtCore.so.4

 ./usr/lib/x86_64-linux-gnu/libQtCore.so.4

find . -name libQtGui.so.4

 ./usr/lib/x86_64-linux-gnu/libQtGui.so.4

find . -name libpng12.so.0

 ./lib/x86_64-linux-gnu/libpng12.so.0

Copy the 3 files to: /usr/lib/x86_64-linux-gnu/

try epson-printer-utility, it should work now

Hope this helps

Thank you! It worked. I just had to install apt install libaudio2 too. First initialization of printer utility not workd. After restart it (only the utility) everything worked.

yeh, otherwise it is libaudio.so.2: cannot open shared object file: No such file or directory

Still having Communication daemon down, Error code = -1 any ideas?
