Amazon Redshift will no longer support the creation of new Python UDFs starting Patch 198. Existing Python UDFs will continue to function until June 30, 2026. For more information, see the [ blog post ](https://aws.amazon.com/blogs/big-data/amazon-redshift-python-user-defined-functions-will-reach-end-of-support-after-june-30-2026/).

To download and install the Amazon Redshift ODBC driver version 2.x for Linux:

1.  Download the following driver: 
   + [x86 64-bit RPM driver version 2.2.0.0](https://s3.amazonaws.com/redshift-downloads/drivers/odbc/2.2.0.0/AmazonRedshiftODBC-64-bit-2.2.0.0.x86_64.rpm)

   + [x86 64-bit DEB driver version 2.2.0.0](https://s3.amazonaws.com/redshift-downloads/drivers/odbc/2.2.0.0/AmazonRedshiftODBC-64-bit-2.2.0.0.amd64.deb) 
     + Linux artifact signature key: [Key](https://s3.amazonaws.com/redshift-downloads/drivers/odbc/2.2.0.0/AmazonRedshiftODBC-64-bit-2.2.0.0.amd64-certificate.pem)

   + [ARM 64-bit DEB driver version 2.2.0.0](https://s3.amazonaws.com/redshift-downloads/drivers/odbc/2.2.0.0/AmazonRedshiftODBC-64-bit-2.2.0.0.arm64.deb) 
     + Linux artifact signature key: [Key](https://s3.amazonaws.com/redshift-downloads/drivers/odbc/2.2.0.0/AmazonRedshiftODBC-64-bit-2.2.0.0.arm64-certificate.pem) 
     + Linux artifact signed hash: [Hash](https://s3.amazonaws.com/redshift-downloads/drivers/odbc/2.2.0.0/AmazonRedshiftODBC-64-bit-2.2.0.0.arm64-signature.bin) 
**Note**  
32-bit ODBC drivers are discontinued. Further updates will not be released, except for urgent security patches.

1. Before installing, verify that AWS signed the driver package. After downloading the package, its signature key (certificate), and its signed hash (detached signature), run the following commands:

   ```
   openssl x509 -in {{SignatureKeyFile}} -pubkey -noout > redshift-odbc-pubkey.pem
   openssl dgst -sha256 -verify redshift-odbc-pubkey.pem \
       -signature {{SignedHashFile}} \
       {{PackageFile}}
   ```

   If the package is authentic, `openssl` prints `Verified OK`. If the output is anything else, do not install the package. Re-download the files or contact AWS Support.

   For example, to verify the x86 64-bit RPM:

   ```
   openssl x509 -in AmazonRedshiftODBC-64-bit-2.2.0.0.x86_64-certificate.pem -pubkey -noout > redshift-odbc-pubkey.pem
   openssl dgst -sha256 -verify redshift-odbc-pubkey.pem \
       -signature AmazonRedshiftODBC-64-bit-2.2.0.0.x86_64-signature.bin \
       AmazonRedshiftODBC-64-bit-2.2.0.0.x86_64.rpm
   ```

1.  Go to the location where you downloaded the package, and then run one of the following commands. Use the command that corresponds to your Linux distribution. 

   On RHEL and CentOS operating systems (RPM), run the following command:

   ```
   sudo yum --nogpgcheck localinstall {{RPMFileName}}
   ```

   Replace `RPMFileName` with the RPM package file name. For example, the following command demonstrates installing the 64-bit driver:

   ```
   sudo yum --nogpgcheck localinstall AmazonRedshiftODBC-64-bit-2.x.xx.xxxx.x86_64.rpm
   ```

   On Debian and Ubuntu operating systems (DEB), navigate to the directory containing the downloaded .deb file and run the following command:

   ```
   sudo apt install ./{{DEBFileName}}
   ```

   Replace `DEBFileName` with the DEB package file name. For example:

   ```
   sudo apt install ./AmazonRedshiftODBC-64-bit-2.x.xx.xxxx.amd64.deb
   ```
