You may simply solve it by following the instructions below:

• You can connect with the VM terminal and run the below command.

borg delete --cache-only BorgRepoName

By using the command, you can determine your BorgRepoName

cd /opt/borg;
cat backupInfo.sh;
#It will return output like these:
BORG_PASSPHRASE=xxxxxxxxxxxxxxxxx borg info ssh://xxxxxxxxxxxx.repo.borgbase.com/./repo;

The ssh://xxxxxxxxxxxx.repo.borgbase.com/./repo; is your Borg repo name. You can use that in the command above.

Example:  borg delete --cache-only ssh://xxxxxxxxxxxx.repo.borgbase.com/./repo;
