While the /opt/Xilinx and /root/.Xilinx directories have been removed, there may be other files scattered throughout the system. Start by searching for files and directories containing "xilinx" or "vivado" in their names. Use the find command in the terminal for this purpose. For example, sudo find / -name "*xilinx*" will search the entire file system for files and directories containing "xilinx". Carefully review the results and delete any files or directories that are clearly related to the previous Vivado installation. Be cautious not to delete any files that are not related to Vivado, as this could cause system instability. Pay particular attention to hidden directories (those starting with a dot ".") in your home directory, as Vivado may have stored configuration files there. Once you have identified the residual files and directories, use the rm command to delete them. For example, sudo rm -rf /path/to/file will remove a file or directory. The -rf option forces the removal, even if the directory is not empty. Again, exercise caution when using this command, as it can permanently delete files.

Step 2: Cleaning Up Environment Variables: Xilinx Vivado often sets environment variables during installation to point to its executables and libraries. These variables may persist even after the software is uninstalled, potentially interfering with a new installation. To remove these variables, you need to edit your shell configuration files. The primary shell configuration file on Ubuntu is .bashrc in your home directory. Open this file in a text editor and look for lines that set Xilinx-related environment variables, such as PATH, LD_LIBRARY_PATH, or XILINX_VIVADO. Comment out or delete these lines. For example, if you find a line like export PATH=$PATH:/opt/Xilinx/Vivado/2022.1/bin, you can comment it out by adding a # at the beginning: # export PATH=$PATH:/opt/Xilinx/Vivado/2022.1/bin. After editing the .bashrc file, save it and run source ~/.bashrc to apply the changes to your current terminal session. You may also need to check other shell configuration files, such as .profile or .bash_profile, for Xilinx-related environment variables. Repeat the process of commenting out or deleting the relevant lines in these files as well.

Step 3: Removing APT Packages (If Applicable): If Xilinx Vivado was installed using the Advanced Package Tool (APT), you might need to remove the associated packages before reinstalling. Use the following commands in the terminal to list and remove Xilinx packages: sudo apt list --installed | grep xilinx This command will list all installed packages containing "xilinx" in their names. Review the list and identify any packages that are clearly related to Vivado. To remove a package, use the command sudo apt remove <package-name>. Replace <package-name> with the actual name of the package you want to remove. For example, sudo apt remove xilinx-vivado-2022.1. You can also use the purge option to remove configuration files associated with the package: sudo apt purge <package-name>. This will provide a cleaner removal, but be cautious as it will also delete any user-specific settings. Repeat this process for all relevant Xilinx packages. After removing the packages, it's a good practice to run sudo apt autoremove to remove any orphaned dependencies that are no longer needed. This will help keep your system clean and prevent potential conflicts.
