Upgrade certbot 0.14.2 on Ubuntu 14.04

Help
1

Hello,
my domain is www.platform1online.com
We are using CertbotACMEClient/0.14.2 (certbot; Ubuntu 14.04.5 LTS) Authenticator/webroot Installer/None (renew; flags: n) Py/2.7.6
We received a message to upgrade it until Jun 1.
However
sudo apt-get update
sudo apt-get install certbot
does not upgrade anything.
What we could do to upgrade our client ?
Thanks a lot

Hi @elrod68

if an update doesn’t work, perhaps switch to another client. May be acme.sh works.

Hi I'm in the same situation (certbot 0.21 on Ubuntu 14) and my certificates will expire on 2 June.
Is it possible to postpone this upgrade?
