Extracts an Opera Debian package and installs it into /usr/local. An uninstall script is also created and installed as well. Upgrades work if you used this script to install a previous version. Completely unofficial and unsupported by Opera Software.

README.md

Disclaimer: I wrote this script for my own personal usage. It is not officially supported by Opera Software.

Whilst Opera currently only provide .deb packages, it is possible to install Opera on different distros. This install script automates the process.

If you don't already have the script, fetch it like so:

git clone https://gist.github.com/ace4fb780216aa28d922.git

To install the latest stable release, issue:

sudo sh install-opera.sh

To install the latest beta release, issue:

sudo sh install-opera.sh --beta

To install the latest developer release:

sudo sh install-opera.sh --developer

Alternatively you can install a specific build like so:

sudo sh install-opera.sh opera-stable_26.0.1656.32_amd64.deb

After install, you may need to re-login to your desktop environment before Opera is detected.

Note: A script to uninstall Opera is also placed on your system, to aid removing Opera later, should you wish to.

If you would like to ensure that Opera developer is automatically kept up to date, move the script to /usr/local/bin and make it executable:

sudo mv install-opera.sh /usr/local/bin/install-opera
sudo chmod +x /usr/local/bin/install-opera

You could then add the following to root's crontab:

00 18 * * 1-5 /usr/local/bin/install-opera --stable >/dev/null 2>&1

This would execute the script once a day at 18:00 (6pm), every Monday through Friday.

If you would like to schedule the script to run at different times, or would like to log the output and/or errors, read one of the many crontab guides found on the internet.

Note: You should not run this script more once per day, since we never release so frequently. Hammering Opera servers with requests could get your IP address banned and you would then receive no updates. In any case, If you ever notice that a new Opera is out and the script has not yet run, simply issue install-opera --stable manually to trigger an update right away.

@stogdan My script installs Opera into /usr/local not the top level of /usr. I suspect this is the very first desktop orientated program you have installed into /usr/local, therefore your Gnome 3 is not yet scanning /usr/local/share/icons/hicolor/. You can rectify this by logging out of Gnome 3 and then back in again. After this point the icon will be found, just like any other application.

You can also confirm for yourself that the desktop and icon files are present via the following command:

$ ls /usr/local/share/applications /usr/local/share/icons/hicolor/128x128/apps

P.S. I install into /usr/local as this is the correct place for software that is outside of the default package manager (in your case rpm).

I have now added a comment to the README.md so others are not confused by this. So thanks for pointing this out and reminding me.

I have tweaked the install script to do a network install of Opera stable if no options are provided and no deb defined, stopped installation if the same version is already present, changed it so that compatibility symlinks are only created if needed and set sandbox permissions in post install (which should be more robust).

Hi, I ma trying to use it on Fedora 21 fresh installation but it ends on
Uncompressing Opera ...
Touch ... „usr/local/lib64/opera/VERSION_28.0.1750.48“ ...does not exists... and it really does not. All files remains in tmp

Any help?

Yes, I have a patch to fix it.

Just the icons I cannot see it on KDE Launcher. Any ideas?

@ftonello: yep, looks like I broke the script after my last update to remove the udev and libcrypto workarounds. Thanks for helping @Pepan out. I have updated the script now.

Did you follow the steps in the README.md

After install, you may need to re-login to your desktop environment before Opera is detected.

The problem is that KDE will not look for icons under /usr/local/share/icons/hicolor/ if none are there when it first starts up. A relog will fix this.
