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:

An error occurred while extracting files. The file content is encrypted, but currently not supported.

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.

Description: 7z and 7za file archivers with high compression ratio
 p7zip is the Unix command-line port of 7-Zip, a file archiver that
 handles the 7z format which features very high compression ratios.
 .
 p7zip-full provides utilities to pack and unpack 7z archives within
 a shell or using a GUI (such as Ark, File Roller or Nautilus).
 .
 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.
 .
 List of supported formats:
   - Packing / unpacking: 7z, ZIP, GZIP, BZIP2, XZ and TAR
   - Unpacking only: APM, ARJ, CAB, CHM, CPIO, CramFS, DEB, DMG, FAT,
     HFS, ISO, LZH, LZMA, LZMA2, MBR, MSI, MSLZ, NSIS, NTFS, RAR (only
     if non-free p7zip-rar package is installed), RPM, SquashFS, UDF,
     VHD, WIM, XAR and Z.
 .
 The dependent package, p7zip, provides 7zr, a light version of 7za,
 and p7zip, a gzip-like wrapper around 7zr.
