In the world of Ubuntu, one of the common errors that users may encounter is the “sha1sum mismatch” error when using Winetricks. This error typically occurs when the sha1sum of a downloaded file does not match the expected value. This article will guide you through several methods to fix this issue.
To fix the "sha1sum mismatch" error when using Winetricks in Ubuntu, you can try renaming the problematic file, updating Winetricks, using the built-in self-update function, or manually updating the sha256 sum in the Winetricks script.
What is sha1sum?
Before we dive into the solutions, let’s understand what sha1sum is. The ‘sha1sum’ is a cryptographic hash function that takes an input and produces a 160-bit (20-byte) hash value. This hash value is typically rendered as a hexadecimal number, 40 digits long. It’s primarily used to verify the integrity of files.
Understanding the Error
The “sha1sum mismatch” error usually means that the file you’ve downloaded is not the same as the file Winetricks expected to download. This could be due to several reasons such as the file being updated on the server but not in the Winetricks script, or the download being corrupted.
Solution 1: Rename the File
One of the simplest solutions is to rename the problematic file. Here’s how you can do it:
- Open a terminal. You can do this by pressing
- Run the following command:
mv -v /home/.cache/winetricks/win2ksp4/W2KSP4_EN.EXE /home/.cache/winetricks/win2ksp4/W2KSP4_EN.EXE_bak
This command renames the problematic file, forcing Winetricks to download it again. The
-v option makes the ‘mv’ command verbose, meaning it will show what it’s doing.
Solution 2: Update Winetricks
If the first solution doesn’t work, updating Winetricks might solve the issue. Here’s how:
- Open a terminal.
- Remove the current version of Winetricks by running:
sudo apt-get remove winetricks
This command removes the current version of Winetricks installed on your system.
- Download the latest version of Winetricks by running:
The ‘wget’ command is a free utility for non-interactive download of files from the web.
- Make the downloaded file executable by running:
chmod +x winetricks
The ‘chmod’ command changes the permissions of the file. The ‘+x’ makes the file executable.
- Move the downloaded file to the appropriate location by running:
sudo mv -v winetricks /usr/local/bin
This command moves the updated Winetricks file to the ‘/usr/local/bin’ directory where executable files are usually stored.
Solution 3: Self-update Winetricks
Winetricks also has a built-in self-update function. You can use it by running:
sudo winetricks --self-update
This command updates Winetricks to the latest version.
Solution 4: Manually Update the sha256 Sum
If none of the above solutions work, you can manually update the sha256 sum in the Winetricks script.
- Open a terminal.
- Check the sha256 sum of the problematic file by running:
- Find the line in the shell script that contains the sha256 sum:
grep PowerPointViewer.exe /usr/bin/winetricks
- Replace the old sha256 sum with the new one:
sudo sed -i -e s/old_sha256_sum/new_sha256_sum/g /usr/bin/winetricks
Make sure to replace “old_sha256_sum” and “new_sha256_sum” with the actual values obtained from steps 2 and 4.
The “sha1sum mismatch” error in Winetricks can be frustrating, but it’s usually easy to fix. The solutions outlined in this article should help you resolve the issue and continue using Winetricks without any problems. If you’re still encountering issues, consider seeking help from the Ubuntu community.
Remember, it’s always good practice to keep your system and applications updated to avoid such issues. Happy troubleshooting!
Winetricks is a script that allows users to easily install and configure various Windows applications and libraries on Linux systems using Wine, a compatibility layer that allows running Windows applications on Linux.
To open a terminal in Ubuntu, you can press
Ctrl+Alt+T on your keyboard. This will launch the default terminal emulator.
-v option in the
mv command stands for "verbose." When used, it makes the command display the actions it is performing, providing more detailed information.
To remove a package in Ubuntu, you can use the
apt-get remove command followed by the package name. For example, to remove Winetricks, you can run
sudo apt-get remove winetricks.
wget command is a utility for non-interactive downloading of files from the web. It allows you to download files from URLs directly to your system.
To make a file executable in Ubuntu, you can use the
chmod command with the
+x option. For example,
chmod +x filename will make the file named "filename" executable.
--self-update option in the
winetricks command is used to update the Winetricks script itself to the latest version. It ensures that you have the most up-to-date version of Winetricks installed on your system.
To update a file’s sha256 sum in the Winetricks script, you can use the
sed command. By specifying the old and new sha256 sums, you can replace the old sum with the new one in the script. For example,
sudo sed -i -e s/old_sha256_sum/new_sha256_sum/g /usr/bin/winetricks will update the sha256 sum in the Winetricks script.
