problem

I tried installing the Emerald icon theme in Ubuntu, and the theme was packaged as a.7z archive. As always, I tried to decompress it by right-clicking in the GUI and selecting Extract Here. However, Ubuntu 15.04 did not extract the file. Instead, it gave me the following error message:

The code is as follows:

Could not open this file

cannot open the file

There is no command installed for 7-zip archive files. Do you want to search for a command to open this file?

No commands are installed for 7-zip archive files. Do you want to search for commands to open this file?

The error message looks like this:

reason

The reason for this error is obvious from the error message itself. 7Z, better known as 7-zip, is not installed, so the 7Z archive cannot be decompressed. This also implies that Ubuntu does not support 7-zip files by default.

Solution: Install 7zip in Ubuntu

To fix this problem, install the 7-Zip package in Ubuntu. Now, you might be wondering how to install 7Zip in Ubuntu? Well, in the previous error dialog box, if you right-click on the Search Command search command, it looks for available p7zip packages. Just click "Install" to install, as shown below:

Option: Install 7Zip in terminal

If you prefer to use a terminal, you can install 7zip in the terminal using the following command:

The code is as follows:

sudo apt-get install p7zip-full

Note: In Ubuntu, you will find three 7zip packages: p7zip, p7zip-full, and p7zip-rar. The difference between p7zip and p7zip-full is that p7zip is a lighter version that only provides support for.7z and.7za files, while the full version provides support for more 7z compression algorithms (for audio files, etc.). For p7zip-rar, it provides support for.rar files in addition to 7z files.

In fact, the same error happens to RAR files in Ubuntu. The solution is the same, just install the right program.
