dovecot fail about a semicolon who doesn't exist

Thanks for taking the time to report this bug and trying to make Ubuntu better.

In order to better understand your issue, we need some information like: which Ubuntu release are you using? Which version of dovecot do you have installed? Did you make any manual change in the configuration files to reach this state?

I launched a Ubuntu Kinetic (current development release) container to take a look at this, and after installing dovecot-core the service gets up and running as expected.

This ssl setting you pasted in the bug description was changed by debian some time ago, and no one complained so far. My initial feeling is that this is not the root cause of your issue.

I am setting the status of the bug to Incomplete, once you provide more information please set it back to New and we will take a look again.

i use ubuntu 22.04,

the kernel is that :

'''uname -a
Linux Ubuntu-ThinkPad-X250 5.15.0-43-generic #46-Ubuntu SMP Tue Jul 12 10:30:17 UTC 2022 x86_64 x86_64 x86_64 GNU/Linux
'''

the version of dovecot is that :

'''dovecot --version
2.3.16 (7e2e900c1a)
'''

i don't see any file dovecot.conf as shown below :

'''locate dovecot
/etc/apparmor.d/abstractions/dovecot-common
/etc/apparmor.d/tunables/dovecot
/snap/core18/2538/etc/apparmor.d/abstractions/dovecot-common

~$ whereis dovecot.conf
dovecot.conf:
~$ locate dovecot.conf
~$
'''

thanks you in advance to help myself repair dovecot for use it,

regards.

Dorian ROSSE.

i went to read dovecot.conf in /etc/doveco and i don't see any designing,

i copy past from doveco.conf each line uncommented :

'''

!include_try /usr/share/dovecot/protocols.d/*.protocol

dict {
  #quota = mysql:/etc/dovecot/dovecot-dict-sql.conf.ext
}

!include conf.d/*.conf

!include_try local.conf

'''

i let you read my previous answer where the other ask are answered as the version of ubuntu and the version of doveco,

thanks you in advance to help myself repair doveco for use it,

regards.

Dorian ROSSE.

Could you also show the contents of /etc/dovecot/conf.d/10-ssl.conf?

i paste below :

Dorian, the issue may be a typo in one of your other config files, e.g. a missing close bracket.

Please attach your /etc/dovecot/conf.d/10-master.conf file.

Also, let's see this:

  ls -l /etc/dovecot/conf.d/

hello,

i have put in attachment that you ask,

thanks you in advance to help myself repair dovecot,

Hi Dorian,

I think your problem is at the end of your 10-master.conf:

service dict {
unix_listener dict {
    mode = 0660
    user = vmail
    group = vmail
}

You are missing a curly bracket at the end of the file. These settings are shipped disabled so guessing these got configured on at some point in the past, so perhaps the typo occurred then? Let us know if this fixes things for you.

hello,

now we pass this error i am got another error that i don't understand well thus it say it miss one opening bracket on line 33 unfornately i have tried at the begun of the line or else a the end of the line finally the program keep this error i paste firstly the code then i paste systemctl :

thanks you in advance for your help,

Hi Dorian,

Thank you for taking the time to report bugs and help make Ubuntu better.

This looks like a local configuration issue rather than a bug in the software itself. Please check your configuration to make sure it's correct. If you need help configuring, you can get community support in the Ubuntu channels on freenode.net, or in http://www.ubuntu.com/support/community

I'm marking this "Invalid" because it doesn't appear to be a bug, but if I'm wrong, please change it back to "New" and add some more info to point me in the right direction. Use this link as a guide: http://www.chiark.greenend.org.uk/~sgtatham/bugs.html
