@teddkon Yes, I tried that. I think I reported that. The problem I had was, for whatever reason, the snap installation was unable to import/use the bookmarks, passwords, etc, (of which I had a lot) from the .deb installation, so it was worthless for me. Yes it did solve some of the codec issues.

I have abandoned Opera and moved back to FireFox which has greatly improved since I use it a few years back. Plus I don't have to concern myself that Opera is now essentially owned by the ChiComs and all the dirty tricks these folks play in their cyber warfare.

@fonm That probably would solve the dependency problem. But I went through the pain and suffering of the long overdue rebuilding of my workstation to upgrade both the hardware and to install Mint 20. The dependency problem didn't occur anymore.

However, even now, Opera will still not work with things like Twitch and a few other stream content formats. I still get : This video is either unavailable or not supported in this browser. (Error #4000)

I tried adding all kinds of codecs to try to solve the problem, but get the usual error code. I tried to remove ad and tracking blockers to see if that would help. Nope.

Is it too hard for the Opera" developers to test their browser against popular websites, and fix problems which I find are reported extensively for Linux installations?

I'm an end-user, not a browser developer. I've wasted way too much time on this and other issues with Opera. Except for the very good text-flow function on Android apps which works great on my tablet, Opera has no compelling reason to be used over browsers such as Firefox.

Sorry for the rant, but I've had it with Opera.

Thank you for your suggestion. --Fred

@user-opera1982 I believe this all stems from my having an older version of Mint. I decided it was time to do a major upgrade, but as usual, the upgrade failed miserably on the final step because of the virtual file system on the machine. Since it was time to also upgrade hardware, I did a build on a newer box. I had sufficient backups, but because I had a lot of development packages, it was a very time consuming process.

Yes, I had previously tried your suggestion, but that didn't resolve things. Thank you anyway.

@sorenfeodor Yes, you're right, I have an older version of Mint, 19, and maybe will upgrade soon. Always risky even with backups and timeshift.

I did try the snap version which did install OK, but it was unable to completely sync with the deb version, either though I have opera synced on 4 devices. I saw no way to import bookmarks & passwords from another local installation, so I abandoned the the snap installation.

Thanks for your response.

@fherman said in Dependency problems on Linux Mint:

Package libqt5gui5-gles is not installed.

Also, Package libqt5gui5-gles is not in the repository, so I can't install it.

opera-stable depends on libqt5gui5 (>= 5.10.0) | libqt5gui5-gles (>= 5.10.0); however:
Version of libqt5gui5:amd64 on system is 5.9.5+dfsg-0ubuntu2.6.
Package libqt5gui5-gles is not installed.

This is an ongoing problem for a last few upgrades of opera-stable. Is this too hard to fix?

@sgunhouse I only see Speed Dial in Bookmarks. Not other speed dials. The folder Speed Dial contains the current bookmarks on the home screen.

I have synced my devices, and have enabled flow on my laptop. When I sync, I see all the speed dials. But the icon of a computer screen with a plus does not show on the laptop speed dial to allow me to add another device's speed dial.

How do I add this icon?

I have the latest version of opera-stable on my laptop.

TIA
