I installed the program "LAN Messenger" from a deb file.

When starting the program I get an error message. I did installed libicui.

tanmn2@TanMN2:~/Downloads$ lmc
This is not a Canonical "designed" product.
Unable to load library icui18n "Cannot load library icui18n: (libicui18n.so.48: wrong ELF class: ELFCLASS64)" 
QGtkStyle was unable to detect the current GTK+ theme.

How should I proceed?

Install the i386 package of libicui:

apt-get install <your_libicui_package>:i386

Replace <your_libicui_package> with your package name.

In your case (Ubuntu 12.04) libicu48 and for Ubuntu 14.04 and newer versions: libicu52

  • OH, sorry, i have no enough reputation :) Can you say to me the lib what I need install here? I replace <your_libicui_package> with <icui18n> and <libicui18n.so.48>, but no such file or directory. Thank you very much!
