erkan-yilmaz last edited byI am getting this error (1). Here they are saying: (2). Could someone have a look please? Thank you! (1) 
 ubuntu 14.04, 32bit:
 Es wurden 597 kB in 22 s geholt (26,2 kB/s).
 Paketlisten werden gelesen... FertigW: Es gibt keine öffentlichen Schlüssel für die folgenden Schlüssel-IDs: 
 63F7D4AFF6D61D45(2) "I think 63F7D4AFF6D61D45 (or just F6D61D45) is a gpg key for the Opera repo, but from what I'm seeing it's not yet on a keyserver so checkaptgpg can't fix the error. The old key (A8492E35) was to expire on 2015-07-03 -- two days from now, so the error is showing up a little bit early."

avl Opera last edited byInstall a package from http://www.opera.com, and you should get the new public key with it.

erkan-yilmaz last edited byThere is no newer package than what I have already: opera_12.16.1860_i386.deb 
 reinstalled via dpkg anyways over it
 But still the error persists Here (1) I see some instructions, but it also says: 
 "The following is almost certainly not needed."
 Should I try those?

avl Opera last edited byIf you're still on Opera 12.16 you'll not get updates in any case, but yes, those steps will stop the error. I see you're on 32-bit. There are newer development versions of Opera for 32-bit Linux available (but no stable version yet) from here: http://blogs.opera.com/desktop/2015/06/opera-developer-32-0-1910-0-bookmarks-tree-view-heart-popup-and-synchronization-improvements/.

mischasch last edited byOn Debian-based distros the easiest solution is: apt-key adv --recv-keys --keyserver keys.gnupg.net 63F7D4AFF6D61D45I found that Opera 12 conflicts with Opera Stable, but installing Opera Next is possible and it is the same build 12.16.1860. It uses ~/.opera-next as the configuration directory, so you might want to create a symbolic link at ~/.opera if copying an existing profile.
