I am trying to refresh repository indexes using Synsptic Package Manager and getting the following error.
An error occurred during the signature verification. The repository is not updated and the previous index files will be used. GPG error: http://deb.debian.org/debian buster InRelease: gpgv, gpgv2 or gpgv1 required for verification, but neither seems installed

Some index files failed to download. They have been ignored, or old ones used instead.
Even I have gpgv, gpgv2 and gpgv1 installed.
This error does not happen on sudo apt update but synaptic throws out this error.
I am new to debian and I do not understand how to resolve this. Please help me out.
