I am sorry that it is not working for you. The deb is also nowadays old and I guess some new certificates are missing.
I would suggest to follow the manual approach you could find links in this post I made:

Otherwise you need to create a deb package there you can specify to remove unwanted certs and only install which you need.

Or make a list with certificates you would like to delete and upload all certificates which you would like to install. I could make then a deb out of it.
