Huh.. Weird. I'll leave this to @certbot-devs or other community volunteers as I have no idea what so ever..

which certbot gives /usr/bin/certbot

History:

   46  add-apt-repository ppa:certbot/certbot
   51  apt-get install python-certbot-nginx
  278  certbot
  361  certbot renew
  369  apt-get remove certbot
  370  snap install --classic certbot
  376  certbot renew --dry-run
  377  snap refresh core

  497  certbot --version

  503  which certbot

Had to put in minimum 6 characters :slight_smile:

Are you using a web-based terminal by any chance? Like, are you typing these commands into a browser?

If you can try using a native SSH client (like ssh or PuTTY or whatever), that might help.

I've seen a couple of users run into this issue, we should look into what effect these terminals are having on the execution environment.

No. I'm ssh'ing from an Ubuntu desktop.

That's bizarre. Doubly so if certbot --version doesn't print anything. I'm not sure. Could you please run:

snap run --strace="-s 1024" certbot --version 2>certbot.log

and post the resulting certbot.log file somewhere?

Maybe those weren't fully undone?

Could be. I have no idea where to look.

apt list --installed|grep cert:

ca-certificates/focal-updates,focal-security,now 20210119~20.04.2 all [installed]
python3-certifi/focal,now 2019.11.28-1 all [installed,automatic]
ssl-cert/focal,now 1.0.39 all [installed,automatic]

Thanks. Nothing really stands out.

Is this installation of Ubuntu running in a Proxmox/CT/LXD environment? I noticed the kernel is older than it should be for Ubuntu Focal.

I don't know how significant that is going to be, but snapd does rely heavily on kernel features. Running Focal on 4.13 instead of 5.x could be having an interaction with snapd.

I suggest giving the pip instructions a try instead, and seeing whether the issue persists with that method of installing Certbot.

Yes. I guess it's about time to get the host off that 17.10 anyway. I'll upgrade and see if that makes a difference.
Thanks so far!

In six months it is five years! Guess I just sort of forgot about that machine as I never have to touch it :smiley:

Three years... since Canonical stopped supporting it. :smiley:

There are better distros for that. :smiley:

Now the host is on 20.4, and it works again.
Thank you @_az for the help!

You actually have three :wink:

ESM doesn't count. As Canonical puts it:
