Installing 7-Zip on Debian/Ubuntu

A guide to installing the latest version of 7-Zip on Debian/Ubuntu. This resolves bugs present in p7zip, such as the inability to compress large files.

Why Manual Installation is Necessary

p7zip is outdated and has bugs (cannot compress files larger than 5GB). The 7zip package in apt repositories is also an older version, so downloading from the official website is required.

Download from the 7-Zip official website
Visit the official download page to find the latest version package and copy the download link.
Official Download Page
```
# Navigate to download directory
cd ~/Downloads

# Download the file
wget -O 7zip.tar.xz download-link
```
Extract the archive
```
tar -xf 7zip.tar.xz --one-top-level
```
Install
Copy the 7zz executable to the /usr/local/bin/ directory to complete the installation.
important
- Since /usr/local/bin is a system executable directory, sudo privileges are required to copy files.
- The 7-Zip executable is named 7zz, which differs from p7zip’s 7z. Therefore, the command after installation is 7zz rather than 7z. For example: 7zz a test.7z test.txt.
- If you prefer to use the 7z command, first remove p7zip to avoid conflicts (if installed), then create a symbolic link pointing to 7zz: sudo ln -s /usr/local/bin/7zz /usr/local/bin/7z.
```
sudo cp 7zip/7zz /usr/local/bin/7zz
```
