Here the first block was running, second block was not. And the problem was EOI considers spaces as dots, I think. But, it does not consider tab as dot. Making no indentation worked for me. But is there any way to specify not to consider tabs or spaces as dots?

ssh -tt -vvv -i $pathToPem -o StrictHostKeyChecking=no $sshUsernameIp << EOI

 sudo rm -rf letsencrypt.tar.gz
 sudo rm -rf /etc/letsencrypt
 sudo rm -rf /usr/local/share/ca-certificates/chain.crt

 sed -e 1b -e '$!d' $remote_home_dir/.bashrc
 sudo add-apt-repository ppa:certbot/certbot -y
 sudo apt-get install certbot -y &
 exit
 trap exit INT

EOI

ssh -tt -vvv -i $pathToPem -o StrictHostKeyChecking=no $sshUsernameIp << EOI

 sudo certbot certonly -n --agree-tos --register-unsafely-without-email --standalone -d $FQDN

Updated
Now, the first part works, when it goes to second part begins at line ############### it says the following:

Command '.sudo' not found, did you mean:

 command 'sudo' from deb sudo
 command 'sudo' from deb sudo-ldap

Try: sudo apt install <deb name>

Someone shared a solution before but later removed it, I think that would work for me. :)

Why is it adding "." in front of all commands?
