the latest version of Nimbus, extract the zipped file, and then run the checksum verification process to ensure that the "nimbus_beacon_node" and "nimbus_validator_client" files have not been tampered with during download.

Each downloadable file comes with it's own checksum. Replace the actual checksum and URL of the download link in the code block above.
Make sure to choose the amd64 version. Right click on the linked text and select "copy link address" to get the URL of the download link to curl.
Expected output: Verify output of the checksum verification.
nimbus_beacon_node: OK
nimbus_validator_client: OK
If checksum is verified, extract the consensus client and validator client binaries into the (/usr/local/bin) directory (as a best practice). Then, clean up the duplicated copies.
cd ~/nimbus-eth2_Linux_amd64_24.2.2_fc9c72f0/build
sudo cp nimbus_beacon_node nimbus_validator_client /usr/local/bin
cd
rm -r nimbus-eth2_Linux_amd64_24.2.2_fc9c72f0 nimbus-eth2_Linux_amd64_24.2.2_fc9c72f0.tar.gz
Restart the Nimbus services
sudo systemctl start nimbusbeacon.service nimbusvalidator.service
sudo systemctl status nimbusbeacon.service nimbusvalidator.service
Monitor journal logs using
sudo journalctl -fu nimbusbeacon -o cat | ccze -A
sudo journalctl -fu nimbusvalidator -o cat | ccze -A
Pruning Nimbus
Consensus clients take up a small amount of disk space when compared to execution clients. However, you can still free up ~200GB by pruning it if your validator node has been running for a while.
To prune consensus clients, simply delete the existing database and restart the beacon service with checkpoint sync enabled.
