Regen-conf not executed

Hi there,

I want to add a value to the postfix and tried to stick to the method of using a regen-conf hook.
Unfortunately it seems like this script is never executed.

How can I confirm, if the hook is executed, or am I doing something really wrong?

Thanks for your help




# Check if everything is in place
[[ $action == "pre" ]] || exit 0
[[ -e $postfix_conf ]] || exit 0

awk -i inplace '{if (/^virtual_alias_maps = /) {$0=$0 ",regexp:/etc/postfix/aliases-regexp"}; print}' $postfix_conf

Probably the issue is with the name of the script … You might want to name it just 02-postfix

As Aleks says, The name must be of the form: xx-postfix_whateveryouwant
xx is a number, it must be higher than 19 otherwise the default configuration will overwrite your modification. See /usr/share/yunohost/hooks/conf_regen to determine the number, each service has a different number.

Then, your script must be rename like 20-postfix_regexaliases



thank you for your suggestions.

I just renamed it to 20-postfix_regexaliases.

Still it seems like it’s not getting executed.

Do you have another idea?

Thank you1

Where is your script? It must be in the folder /etc/yunohost/hooks.d/conf_regen/

Did you run:

yunohost tools regen-conf postfix --force

You can check the file:

grep virtual_alias_maps

The result must be:

virtual_alias_maps = ldap:/etc/postfix/,regexp:/etc/postfix/aliases-regexp

from the title in nano:

I did run

yunohost tools regen-conf postfix --force

I checked the afterwards. I meant, maybe there are debug logs indicating whether the script was executed or if there was a problem executing.

Thanks for your help!

Humm…perhaps with --debug option to see how the regen-conf is run?

You can use the options --dry-run to show what would have been regenerated and --with-diff to show differences in case of configuration changes.

I recommend you to delete your script (or move it elsewhere) and regen-conf --force to restore the original version of Then you can try after putting the script in /etc/yunohost/hooks.d/conf-regen:

yunohost tools regen-conf postfix --force --dry-run --with-diff

If it’s OK, you can use the --debug option to see details:

yunohost tools regen-conf postfix --force --debug

I just test your script with --dry-run --with-diff and it’s OK , there’s no problem. I don’t understand why it don’t run for you:

yunohost tools regen-conf postfix --force -n -d        
Success! The configuration would have been updated for category 'postfix'

I’m puzzled.

I just deleted the whole conf-regen directory and recreated it, incuding the 20-postfix_regexaliases file.

Still, if I run

yunohost tools regen-conf postfix --force --dry-run --with-diff

It doesn’t show my modification but only the unaltered file.

I don’t get it…

It’s strange!
Could you run in debug mode please. And give the access right:

ls -la /etc/yunohost/hooks.d/conf_regen/
yunohost tools regen-conf postfix --force -n -d --debug

Oh, no.

I found the issue.

The directory i had the script in was conf-regen but it should have been conf_regen.

Thank you so much for your help, it works now - as expected.
