[ALUG] rsync

I'm sure this is trivial but I don't know where to look... My wife's PC uses Grsync (gui for rsync) to backup to my server. I've recently put a new HDD in the server and re-installed everything, including a new SSL cert via Certbot. Now her Grsync refuses to connect because the certificate has changed. I guess sudo apt purge grsync then re-install it would do it but is there a more elegant method? Some config file I can edit or delete? -- Phil Thane www.pthane.co.uk Tweet @pthane 01767 449759 07582 750607
