The solution given works for me. The only thing I've noticed is that the highlight on the main menu accessible from the Opera button is missing when using the dark theme; with the light theme everything seems normal for me. Every site I've visited works, including YouTube. Considering that Ubuntu 16.04 Xenial, a long term support version of the OS, is supported until April 2021 it's a real pity that Opera 69 and above can only now be installed by rebuilding a deb package. Surely Opera should always run on all LTS versions of Ubuntu while they continue to be supported? Otherwise people who have been loyally using Opera for years, in this case over four years, will suddenly find that their system no longer updates via the Opera repository and that the lastest deb packages can't be installed on their system without any warning.

RE: Opera 69 comes with built-in TwitterBlogs
@leocg: The latest version of Vivaldi, based on Chromium 83.0.4103.119, installs and works perfectly on Xenial. And Opera 69 also works on Xenial without much of a problem, the only thing wrong seems to be a missing highlight bar on the Opera menu not being visible when using the Opera's dark theme. Because Opera is so good I am willing to download DEB packages manually and rebuild them, so that they install in the usual way, to run on Xenial until something else changes or Xenial's support ends in April 2021. Still, it would have been nice if Opera 69+ could have been finessed to enable it to update with the operating system, rather than manually, because a lot of people won't be bothered to unpack, alter and repack the DEB package to keep Opera, which is a pity because it really is the best browser in the world in my opinion.

RE: Opera 69 comes with built-in TwitterBlogs
The latest version of Opera doesn't work on LTS Ubuntu 16.04 Xenial or any of the variants that are built upon it, e.g., Linux Mint 18.x. Why? Because the new Opera unnecessarily uses a version of libgtk later than that of Xenial which doesn't reach its end of support until next April. Opera 69 needs libgtk-3.19.12 and Xenial only has libgtk-3.18.9 which is difficult and dangerous to upgrade and not something to do rashly, certainly not to run one particular application no matter how good it is. There are thousands and thousands of Xenial users out there which use Opera that now cannot install the latest and later versions of the browser using APT or from DEB packages without taking them apart, altering and rebuilding them so that they can be installed and made to work with libgtk-3.18.9. Opera 69 does work with Xenial's version of libgtk for the most part apart from an issue with the drop-down menu accessible via the Opera button, namely the option highlight is dark and opaque.
If the next version of Opera could be tweaked to use libgtk-3.18.9, at least until Xenial's support ceases, the browser could be updated and installed as before pretty much automatically, with the operating system, via APT. Thousands upon thousands of longstanding Opera users who have relied on that browser for years would be grateful I assure you.
Thank you.

RE: Opera 69 comes with built-in TwitterBlogs
@horaink If you are using Ubuntu 16.04 Xenial the latest version of Opera can't be downloaded and installed using APT due to a dependency problem involving libgtk. Opera 69 needs libgtk-3.19.12 and Xenial only has libgtk-3.18.9 which is dangerous to upgrade and not something to do rashly. If you want to keep using Opera 69 and above you have to download the latest deb package from the Opera website and either extract it to a directory with file roller and run it from there using the terminal or a custom made shortcut, or, alternatively extract, alter and rebuild the deb package as described here:
https://forums.opera.com/topic/41676/solved-missing-dependency/17
Then install it manually.
(All updates in future will need to be done by the same means.)
Everything seems to work perfectly, for me at least, other than a highlight missing from the Opera menu when using the dark theme. In my view Opera is such a great browser that the small investment of time described above is well worth it until next April when Xenial reaches the end of its long term support.
A real pity that the Opera team never noticed the problem however because on Xenial Opera stops offering updates from its repository without any warning leaving huge numbers of loyal Opera aficionados in the dark about what has happened.

Hi. New version released for Linux but no update has been offered via the Opera Linux repository. Any hope of getting the latest version from the repository in the near future. Looks nice. Thank you.
