Can't install Opera 51 on Ubuntu 14.04 LTS

Sorry, my bad, you sounded like an opera dev :o)
My apologies

If opera breaks the whole distro on 18.04, it looks a lot to me like opera would add a library which replaces the distro library... and this would never happen if opera was a single and unique .deb package statically build (and bringing no other dependencies). One more reason why opera devs should strongly consider static builds

Again, to not get mistaken, I'm strongly against static builds for distro packages, but definitely "for" static builds concerning 3rd party proprietary packages.

Kind Regards

Seems like, as long as the signatures of the libdbus-1-3 library functions opera actually uses are unchanged, and their semantics remain compatible, the dependency could be safely left downrev. In my case >=1.8.20 would work just fine even if the library was actually at - say - 1.9.14.

This issue should be fixed in recent released Opera 52.

Actually no, opera 52 still depends on libdbus 1.9.14 or newer, so the problem still applies for users of old distros

$ apt-cache show opera-stable 
Package: opera-stable
Version: 52.0.2871.30
...
Depends: ... libdbus-1-3 (>= 1.9.14),

You obviously meant the issue with libcurl3/4.

@jimunderscorep Even those that follow the minimum requirements : https://www.opera.com/pt-br/download/requirements?

I don't get you. Can you be more specific, please?

All the complaints made in this thread here start from one small change on the version of a lib that opera depends on. I think I nave analysed the "why" behind that change as much as possible on my posts above.
Opera 52 depends on the exact same version of libdbus that opera 51 was and that alone is what makes it impossible to install on old distros, so nothing has changed to all I say except for opera's (and chromium's) version number.

@jimunderscorep As far as I know, they fixed that issue but the fact that you need at least Ubuntu 16.04 didn't change.

There are a lot of browsers in the market. Should Opera insist only supporting Ubuntu 16.04 starting from Opera 51, the only choice we users can do is to stay with Opera 50 or stop using Opera. I don't think Opera team will give in based on the small user base of Ubuntu 14.04.

There are obviously many other browsers out there for someone looking a substitute for opera on an old distro, but

How many of them are built with a good browser engine like firefox's gecko or chrome's blink and not some webkit fork for qt/gtk? A good browser engine is the key feature that provides decent performance to today's web pages whose complexity is increasing every year.

How many of them draw their ui with a good toolkit like gtk or qt and not with today's really famous crap, electron, like vivaldi, min and brave do? For me, this is a major issue, because I refuse to use an app that uses a huge amount of libs and an engine ONLY to draw its ui and nothing more. The reason behind that is usually a lazy dev that does not bother to build the application's ui with a nice toolkit.

If you are disappointed by opera's decision to move forward and drop support for distros that use an older version of some lib, you are free to use chrome which depends on an even older version of libdbus than opera 50 used to. Keep in mind however that asking for support on an 4-year old distro is pretty much the same as asking for support for an os like vista, which is neither supported by chrome or firefox right now.

Kinda offtopic, but since qt4 was mentioned on this thread, ubuntu drops support for qt4 completely for the next year's release

@leocg I think the reason for opera's ubuntu 16.04 requirement is that it has version 1.10.6 of libdbus-1-3. Again, if the set of functions in that library that opera actually uses hasn't changed, then it seems that the version dependency could be safely left down rev. That would have the advantage of increasing the target population of installable systems, which I think opera would have in interest in maximizing.

A Former User

Opera 51 was released like ~1.5 months ago. If the there was someone really, REALLY interested to make it install and test it on 14.04, he would change the control file so as to list libdbus 1.2.x (or whatever opera 50 had) as dependency and install it.

But no. This thread has 30+ comments (and 4500+ views) at the time I am writing this. Most them are either mine explaining the obvious "why linux sucks as a desktop os" situation or others complaining with "but this browser does install" examples. Why? Because complaining is easier than admitting something. I even got a downvote from someone who can not accept how things are,

Well, I guess I'm really talking for the benefit of opera as a business. A quick look at Distrowatch shows that Mint, Manjaro, and Debian all are downloaded more than Ubuntu. In addition there are many other deb based distributions (my own is Devuan Jessie) that would seem to argue for anyone distributing on a Linux based platform to be interested in supporting.
So the takeaway is that downrevved dependencies help maximize the potential market. Hopefully the fine folks at Opera will incorporate that observation in evaluating dependency policy going forward.

... just one man's opinion, folks.

I'm just replying from Opera 52 under Linux mint Qiana (Ubuntu Trusty)

To do this I did the following:

fakeroot
dpkg-deb -R opera-stable_52.0.2871.30_amd64.deb opera-stable_52
vim opera-stable_52/DEBIAN/control # Change to "libdbus-1-3 (>= 1.6.18)" and save
dpkg-deb -b opera-stable_52 opera-stable_52_trusty.0.2871.30_amd64.deb
exit

The repackaged file is here:
https://storage.fr1.cloudwatt.com/v1/AUTH_71c6d0f9c3eb4f5a95cebeae99f3b468/Opera_Repackaged/opera-stable_52_trusty.0.2871.30_amd64.deb

So now I confirm it works with "libdbus-1-3 (>= 1.6.18)" so could Opera devs learn how to package things as I mentionned before?

Hope this helps.

Thanks for making the patched deb package available. Unfortunately, wget fails with this message:

Read error at byte 43323441/55094366 (The TLS connection was non-properly terminated.). Giving up.

In the meantime, over at Debian Repository Unofficial, you can follow the link to Google Chrome to download Chrome 65. Installing the deb package also creates an entry under /etc/apt/sources.list.d so that subsequent updates to chrome are enabled. Chrome 65 works fine under Devuan Jessie, and it is fast.

@bbatten strange, have you tried with curl or with a browser?

Sorry, replace _o by -o before the file name in the curl command

@bbatten Maybe you have a network issue, for me both wget and curl work:

If it's a network issue, it's a weird one; I have all the network functionality I need to login and reply to your post. Maybe path speed is too slow (see end of post)? Anyway, I tried the download twice yesterday using Firefox, then once more using wget, failing with each.

Earlier this morning I pasted your wget command line into a terminal window, and that failed:
...
2018-03-28 12:07:09 (10.1 KB/s) - Read error at byte 44443264/55094366 (The TLS connection was non-properly terminated.). Giving up.

Then I pasted your curl command line into a terminal window and that failed too:

% Total % Received % Xferd Average Speed Time Time Time Current
Dload Upload Total Spent Left Speed
3 52.5M 3 1859k 0 0 10726 0 1:25:36 0:02:57 1:22:39 13177curl: (18) transfer closed with 53186694 bytes remaining to read

Maybe the line speed is too slow (@10-14 KB/sec)?

So anyway, right now, I'm trying an experiment using wget in which I simply repeat the command after each failure termination on the assumption that it will just pick up where it left off the last time --- aka "Hail Mary"!

I'll post results.

@bbatten It lloks indeed like a bandwith issue and the connection is closed before the end of download.

Simply modify the original deb if you can get it from opera and then in the download directory of the original fil you can copy paste what follows in a terminal:

sudo apt-get install fakeroot # (If fakeroot is not installed)
fakeroot # this simulates a root environment to preserve file permissions
dpkg-deb -R opera-stable_52.0.2871.30_amd64.deb opera-stable_52 # unpackage the original
sed -i s/'libdbus-1-3 (>= 1.9.14)'/'libdbus-1-3 (>= 1.6.18)'/ opera-stable_52/DEBIAN/control # change the requirement
dpkg-deb -b opera-stable_52 opera-stable_52_trusty.0.2871.30_amd64.deb # rebuild a new package
exit # exit fakeroot environment

You can batch copy/pase all the lines above (with the comments) in a terminal.
<crtl-c> the whole lines above and <caps-ctrl-v> in a gnome/mate/etc... terminal (I tested them).
And you will end up having the same pakckage as I uploaded.
Do not worry if the second last line (before the "exit" command) takes some time, it's normal.
