Is your Opera browser not working on your ubuntu desktop?. Then this post may help you.
In some cases when we click on the opera icon , it wont respond. And if we type 'opera' in the terminal it shows the following error.
ERROR: ld.so: object 'libawt.so' from LD_PRELOAD cannot be preloaded: ignored.
/home/human/lib/opera/9.64/opera: error while loading shared libraries: libqt-mt.so.3: cannot open shared object file: No such file or directory
This happens when some libraries get corrupted ,broken or missing.To fix this just do the following steps.
1)human@localhost:~# sudo apt-get install libqt3-mt
If you get the following message
"You might want to run `apt-get -f install' to correct these:
The following packages have unmet dependencies:
libqt3-mt: Depends: libaudio2 but it is not going to be installed
2)then execute the following comand
human@localhost:~# sudo apt-get -f install
It will automatically install the needed packages and the issue must be fixed by now.
thanks & regards
