Ubuntu: The file content is encrypted, but currently not supported
While trying to extract a password protected/encrypted 7-Zip archive on a fresh Ubuntu 20.04 LTS, we got the following error:
To fix the problem, we just installed the p7zip-full package using the apt command.
sudo apt-get install p7zip-full;
After that, we were prompted as expected to input the decryption password and we were able to extract the archive.
Below is the information of the package that was retrieved by apt info.

Installing p7zip-full allows File Roller to use the very efficient 7z compression format for packing and unpacking files and directories. Additionally, it provides the 7z and 7za commands. .
