That's hard to say... 
As things are now, you're using Certbot 0.19.0 and TLS-SNI-01 validation. Renewal will eventually stop working.
If the PPA is upgraded to Certbot 0.21.0 in the next couple months, you won't have to switch to certbot-auto.
That probably didn't do any harm, but you could examine /etc/letsencrypt/renewal/siminchikkunarayku.pe.conf to check if it was created with 0.19.0 or 0.21.0.
The Certbot PPA package includes a systemd timer to automatically renew.
If you use certbot-auto, you need to deactivate the certbot package's timer (by uninstalling the package, or disabling the timer with systemctl), and set up a timer or cron job to run certbot-auto renew.
