If you’re working with web servers installed on Debian systems, you may encounter the “Invalid operation” error, which can be caused by a variety of underlying issues. One way to solve it is to use the compression tool bzip2. This article explains how to install and use bzip2 on a server running Debian to correct this error.
bzip2 is a popular compression and decompression tool for Debian Linux, and can be used to easily compress large files into smaller .bz2 archives. To install it, run the following command:

Using bzip2 on Files
Now that we have bzip2 installed, we can use it to solve the “Invalid operation” error. If you encounter this error, it may indicate that the file you are trying to open has been compressed by bzip2. To decompress the file, you can use the following command:
bzip2 -d filename.bz2
This command will extract the file from the .bz2 archive, leaving you with an uncompressed version of the original file. In some cases, you may also need to compress a file into a .bz2 archive using the following command:
This will compress the file into a .bz2 archive. If you need to preserve the original file, you can also specify a different name for the output archive:
bzip2 -k filename
The “-k” flag tells bzip2 to preserve the original file.
In this article we’ve covered how to install and use bzip2 to solve the “Invalid operation” error on Debian systems. bzip2 is a powerful tool for compressing and decompressing files and can be a valuable asset for system administrators.
