Unpacks an Opera Debian package into a similarly named directory and creates a startup script that will cause Opera to save its profile within this directory (Useful for USB installs). Completely unofficial and unsupported.

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

This script converts an Opera Debian package into standalone (portable) format. If you do not already have it, fetch it as follows:

git clone

Now use the script to convert an Opera package as follows:

sh opera-developer_27.0.1670.0_amd64.deb

When the script is done you will have a suitably directory called. You can run the copy of Opera stored within it as follows:

opera-developer_27.0.1670.0_amd64/run &

Copy or move the directory wherever you like.

if command -v bsdtar >/dev/null 2>&1; then
_extract='bsdtar xOf'
elif command -v ar >/dev/null 2>&1; then
_extract='ar p'
echo 'You must install BSD tar or GNU binutils to use this script' >&2
exit 1
if [ -z "$1" ]; then
echo 'You must specify the path to a locally stored Opera .deb package.' >&2
echo "Example usage: `basename $0` opera.deb" >&2
exit 1
if ! echo "$1" | grep -q 'opera.*[_-]\([0-9]\+\.\)\{3,\}.*\.deb$'; then
echo "$1 is not named like a recent Opera .deb package" >&2
exit 1
if [ ! -r "$1" ]; then
echo "$1 is either not present or cannot be read" >&2
exit 1
outputdir="`basename $1 .deb`"
mkdir -p "$outputdir" || exit 1

cd "$outputdir"
# The SANDBOX section can be removed if you run Opera 29+ and have a Linux kernel of 3.17 or newer (Ubuntu 14.10's 3.16 kernel will also work).

if [ -n "$OPERA_DEVEL_SANDBOX" ]; then

If you want you can avoid escalating to root for every extraction. You will need to have variable OPERA_DEVEL_SANDBOX predefined and pointing to a valid root-owned, setuid sandbox application. You can actually take an Opera sandbox from any recent Opera package. You should be able to continue to use it for multiple releases before needing to update it. To extract and configure the one from Opera 28.0.1719.0 developer for example, issue:

ar p opera-developer_28.0.1719.0_amd64.deb data.tar.xz | tar -xJf- -C /var/tmp --strip 5 --wildcards '*/opera_sandbox'
sudo chown root:root /var/tmp/opera_sandbox 
sudo chmod 4755 /var/tmp/opera_sandbox

Then define the variable (export OPERA_DEVEL_SANDBOX=/var/tmp/opera_sandbox) in your ~/.bashrc or somewhere else you feel is appropriate.

You could actually remove the whole sandbox section if you want to run Opera 29+ on system with a Linux kernel of 3.17 or newer, as the sandbox does not need root privileges on newer kernels to work correctly.
