Upgrade LetsEncrypt properly

Hi,
On my older ISPConfig server I have LetsEncrypt setup with a lot of pain. I have been trying different methods, until finally I got it working. Ind since I don't touch it.
Now I found upgrade warning in /var/logs/letsencrypt/letsencrypt.log :

Code:

2018-02-13 06:14:01,841:DEBUG:certbot.main:certbot version: 0.21.1

Can somebody please point me into right method of upgrading this one? Which method to use?
....or just update ISPConfig and it will do magic behind the scenes?
...or even just pat-get update ?
BTW...OS is Ubuntu 12.04.5 LTS

 

Hi Till,
interesting...in fact I do not remember which method I used when finally got it working, so I am lost now when I do not know how to upgrade. I remember being here on forum said many times, that one should not use this method, but rather that method, where I do not know which is which and which one I used
Any idea, how should I determine which method I used to install?

 

I would suggest you upgrade to 16.04 LTS since 12.04 LTS is no longer supported and by May, 18.04 LTS will be ready.

 

I use 16.04 LTS and I suppose I would try update to 18.04 but is there any tutorial how to do this for server with running ISP? I did move one time for server without ISP - copy all databases, needed files, normally upgrade system from console then - using rsync - move all data to their proper places. That server was for testing purposes and it had not ISP.

 

@Poliman, you may want to follow what @Jesse Norell already suggested in other thread. I took almost similar steps when upgrading mine. I quote:

 

Hmm, so it would be like:
1. Copy required data.
2. Do upgrade or fresh install of OS.
3. Install ISP from Perfect Server tutorial.
4. Move data from backup place to their proper locations.

These steps above are quite general.

 

Hjah...

Code:

# which certbot
You have new mail in /var/mail/root

But I found certbot in /opt/eff.org/certbot/venv/

 

Regarding upgrade...I have very bad experinece with upgrades. I guess all customizations, like LE SSLs for ISPConfig, phpMyAdmin will be gone. Also Apache has different configs from 2.2 further, so my customizations will be gone.
So I have a habit to simply deploy new server, new install and put new hosting customers there. Also to older customers I offer "free" package on new server, which they accept like I would give them something for free and they like me

 

That is a very smart move.
