Unable to install Opera browser on Ubuntu 17.04

Question

I tried to install opera by downloading the .deb file from opera website. Running sudo dpkg -i opera-stable_44.0.2510.1218_amd64 gave the following results:

[sudo] password for user1:

Errors were encountered while processing:
 opera-stable_44.0.2510.1218_amd64.deb"

Opera is currently not available in Ubuntu software store or in Software Boutique. I also tried older opera-stable_44.0.2510.857_amd64.deb and got similar results. I downloaded the package twice thinking it might be any download error but same result.

Solution

Try this:

Open a terminal,

Press Ctrl+Alt+T

Run it:

exec sudo -i
nano /etc/apt/sources.list.d/opera-stable.list

In the file that opens, paste this text:

# This file makes sure that Opera Browser is kept up-to-date
# as part of regular system upgrades

deb https://deb.opera.com/opera-stable/ stable non-free #Opera Browser (final releases)

Ctrl+O

Ctrl+X

Continue running in the terminal:

wget -O - http://deb.opera.com/archive.key | apt-key add -
apt-get update
apt-get install opera-stable

It seems similar error is happens while installing downloaded .deb package. Running "sudo dpkg -i opera-stable_44.0.2510.1218_amd64" gives "Unpacking opera-stable (44.0.2510.1218) ... dpkg-deb (subprocess): decompressing archive member: lzma error: compressed data is corrupt dpkg-deb: error: subprocess <decompress> returned error exit status 2 dpkg: error processing archive opera-stable_44.0.2510.1218_amd64.deb (--install):" more details of the results are provided in my question itself. Thank you for your help.
