Certbot not found - ssl

Question

i installed letsencrypt on my ubuntu 16.04 machine with following command.
sudo apt-get install letsencrypt
Now, i want to define a cronjob to automatically renew my certs with following line.
certbot renew --pre-hook "service nginx stop" --post-hook "service nginx start"
But i always get the error, that the command certbot could not be found.
If i use letsencrypt instead of certbot everything works fine as long as i dont use the --pre-hook and --post-hook.
How to install certbotor is there an alternative command for letsencrypt to define such hooks?
Thanks

Answer 1

For me the following commands working fine.
Install snap
sudo apt update
sudo apt install snapd
Install Core
sudo snap install core
Install Certbot
sudo snap install --classic certbot
sudo ln -s /snap/bin/certbot /usr/bin/certbot
Renew Certbot
sudo certbot renew --dry-run

Answer 2

Follow the official instructions and install certbot with
sudo apt install certbot python3-certbot-nginx
or, in newer Ubuntus that have snap, with
sudo snap install --classic certbot
It will be available in $PATH after that.

Answer 3

Ok i found the solution..
git clone git#github.com:certbot/certbot.git
cd certbot
./certbot-auto renew --pre-hook "service nginx stop" --post-hook "service nginx start"

Answer 4

This worked for me. I have to specify full path when running certbot with elevated privileges
sudo /snap/bin/certbot renew --dry-run
TL;DR
Although I have /snap/bin in my $PATH
echo $PATH
/usr/local/bin:/usr/bin:/bin:/usr/games:/snap/bin
But without providing full path it does not work with sudo. It throws the following error
certbot renew --dry-run
The following error was encountered:
[Errno 13] Permission denied: '/var/log/letsencrypt/.certbot.lock'
Either run as root, or set --config-dir, --work-dir, and --logs-dir to writeable paths.
and it also works if I (while having /snap/bin in root's $PATH as well) switch to power user
sudo -i
and then run any certbot command
Kindly note I'm on debian 10 and using snapd as package manager according to the tutorial https://certbot.eff.org/lets-encrypt/snap-nginx.
As explained here https://unix.stackexchange.com/questions/245772/why-running-command-as-sudo-returns-command-not-found this is kinda expected and approved of behaviour:
sudo tries to be safe when executing external commands. the usual
workaround is to specify the complete pathname of the program. It's
also more secure; it you don't specify the path, it's conceivable that
an attacker could create another program that will be run with root
permissions.
Going on reading further I can see that my PATHs are different
env | grep ^PATH
sudo env | grep ^PATH
There are several solutions (use custom sudo or change sudo $PATH) provided at the thread Command not found when using sudo so one does not have to specify full path.

Answer 5

try to remove using snap

You can try Let's Certbot.
