certbot renewal cron script
Hi.
Is it good for devuan?
cat /etc/cron.d/certbot
# /etc/cron.d/certbot: crontab entries for the certbot package
#
# Upstream recommends attempting renewal twice a day
#
# Eventually, this will be an opportunity to validate certificates
# haven't been revoked, etc. Renewal will only occur if expiration
# is within 30 days.
#
# Important Note! This cronjob will NOT be executed if you are
# running systemd as your init system. If you are running systemd,
# the cronjob.timer function takes precedence over this cronjob. For
# more details, see the systemd.timer manpage, or use systemctl show
# certbot.timer.
SHELL=/bin/sh
PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin
0 */12 * * * root test -x /usr/bin/certbot -a \! -d /run/systemd/system && perl -e 'sleep int(rand(43200))' && certbot -q renewI think about something loke this:
0 */12 * * * root certbot renew --post-hook "service apache2 reload"0 0,12 * * * certbot renew --post-hook "service apache2 reload"

Re: certbot renewal cron script
Your cron entry misses the user field. I made the same error in my cron entry tailor-made for acme.sh 
May be you'd need the full path of certbot, you just check it out, because I'm not sure.

Re: certbot renewal cron script
Your cron entry misses the user field.
Also has error with the 0,12 instead of the properly shown 0/12 for every twelve hours in the example above it for the hour to run field.

Re: certbot renewal cron script
The main question is... should certbot deb package from Debian be patched for Devuan?
this cron task is from original package:
0 */12 * * * root test -x /usr/bin/certbot -a \! -d /run/systemd/system && perl -e 'sleep int(rand(43200))' && certbot -q renewLast edited by IdeaFix (2025-04-24 22:10:00)

No it tells you that changes are needed if running systemd which Devuan does not do so it is proper as it is. The line in the package is correct, the line you suggest to use is the one that is wrongly formatted with the 0,12 shown by you.

Re: certbot renewal cron script
Should i add --post-hook "service apache2 reload" to
I would give.
0 */12 * * * root test -x /usr/bin/certbot -a \! -d /run/systemd/system && perl -e 'sleep int(rand(43200))' && certbot -q renew && service apache2 reloadA try using the same idea it does after the certbot renews the certificate perhaps even /etc/init.d/ apache2 reload as the command to ensure no stupid path problems as happens with cron as it does not have the same path as the user does when it tries to execute commands. I always do this with my entries to ensure it has no choice but to do what I tell it to do. For example my root crontab.
root@9600k:~# crontab -l
# Edit this file to introduce tasks to be run by cron.
#
# Each task to run has to be defined through a single line
# indicating with different fields when the task will be run
snip....
# m h dom mon dow command
## Run my rsync snapshot script at fifteen minutes after it every four hours.
15 */4 * * * /root/bin/snapshot_root.sh > /dev/null 2>&1
## Run trim on my SSD drives every Saturday at 5am borrowed idea from MX Linux.
0 05 * * sat /root/bin/fstrim-MX.sh > /dev/null 2>&1Offline
