SNIKKET_CERTBOT_OPTIONS: unbound variable

[dashohoxha]

Problem:

/etc/cron.daily/certbot: line 18: SNIKKET_CERTBOT_OPTIONS: unbound variable

Solution:

• Either remove set -ueo pipefail, which makes no sense in a scripts that is executed automatically (in my opinion),
• or use the variable with an empty default value, like this: ${SNIKKET_CERTBOT_OPTIONS:-}

For the time being, a workaround is to add SNIKKET_CERTBOT_OPTIONS= to snikket.conf.
