Opera has updated to 9.10. I can’t remember how I installed opera, but I can’t update it using “sudo apt-get dist-upgrade”. This post has exactly the same problem as mine. So, I changed my old stable repository into this “#deb http://deb.opera.com/opera/ etch non-free”, and use this in the terminal to add public key:
sudo gpg –keyserver subkeys.pgp.net –recv-key 6A423791
sudo gpg –fingerprint 6A423791
sudo gpg –armor –export 6A423791| sudo apt-key add –
and then “sudo apt-get update”, “sudo apt-get dist-upgrade”.
