[rmk (Reggie Ho)]

NethServer Version: 7.5.1804 (final)

Module: IMAP Server ?

Did a yum Update recently … I had 305 modules updated . after restart … not able to connect to email server… seems like the IMAP Mail Server stopped working… the SMTP Server is working… according to my email diagnostic… Also not able to connect via RoundCube in Browser…get message “connection to storage server failed”
Check Services Status… all looks normal…
From IMAP Log: mail dovecot: imap(xxxx@xxx.com): Error: Couldn’t load required plugin /usr/lib64/dovecot/lib90_antispam_plugin.so: Module is for different ABI version 2.2.ABIv10(2.2.10) (we have 2.2.ABIv36(2.2.36))

Mail server broken - dovecot antispam plugin

Error: Couldn’t load required plugin /usr/lib64/dovecot/lib90_antispam_plugin.so: Module is for different ABI version 2.2.ABIv10(2.2.10) (we have 2.2.ABIv36(2.2.36)) Any thoughts folks? I notice on github that there has been some recent challenges with dovecot. This failure seems to have occurred since a code update last night is there an easy way to backout the updates from last night? that would get my friends mail server back online i hope!

NethServer Imap problem

NethServer Version: 7.5.1804 Module: your_module Good morning, today I have a problem with my nethserver 7.5, with the module imap. When I visit the page http://NethServer/webmail or http://192.168.1.4/webmail, after login, I have the error (Impossibile connettersi al server IMAP). The same error appears with outlook. Can you help me please? Thanks in advance

[rmk (Reggie Ho)]

Thanks… I updated to Nethserver 7.6 Beta for now… at least I can login and get email.
Also set the “Lock” on in Software configuration…

[vbn (Valther Nielsen)]

Is there any indication when this problem might be solved. Would I have to create a completely new installation to move to the 7.6 beta?
Thanks.

It’s already solved in the beta version.

@vbn

Would I have to create a completely new installation to move to the 7.6 beta?

No, just follow these instructions to upgrade to 7.6.1810 beta: NethServer 7.6.1810 beta development - #6 by davidep

HI all,
problem is happening again in a fresh installation .
Error: Couldn’t load required plugin /usr/lib64/dovecot/lib90_antispam_plugin.so: Module is for different ABI version 2.2.ABIv10(2.2.10) (we have 2.2.ABIv36(2.2.36))
I first installed the stable 7.5 last version, then updated to testing repo and now upgrade to 7.6 without luck…
What can I try to get rid of these errors and have IMAP working again?
BR
Stefano

[mrmarkuz (Markus Neuberger)]

Did you try this procedure?

NethServer 7.6.1810 beta development

It is now possible to upgrade to NethServer 7.6.1810 beta with the following commands config setprop subscription NsRelease 7.6.1810 Then go to Software Center and run system upgrade set the Software updates origin to “Locked” until 7.6 final has been released Check for open issues again here: https://github.com/NethServer/dev/issues

Maybe try to install from new beta ISO?

NethServer 7.6.1810 beta development

The BETA iso is out: http://mirror1.nethserver.org/beta/ Download and report here md5 0e69e9096289451d757f1e73208bef91 sha1 8a864e81d375bee4b6c1ba4b7375aea643647c33 .torrent ~1GB E34DD54530C4842F5073D62DDC8B12C2E8C3314B To enable the 7.6 repos after the install, execute: config getprop sysconfig Version > /etc/yum/vars/nsrelease /cc @quality_team /cc @LayLow I added the command to enable the repos

EDIT:

Tested it on NS 7.5 with LDAP, mailserver and roundcube:

• updated packages in Software Center “unlocked” mode
• now I can’t login to roundcube and see this in /var/log/imap:
  Error: Couldn't load required plugin /usr/lib64/dovecot/lib90_antispam_plugin.so: Module is for different ABI version 2.2.ABIv10(2.2.10) (we have 2.2.ABIv36(2.2.36))
• updated to Neth 7.6 via Software Center as described here and now I can login to roundcube again and there’s no error in /var/log/imap anymore

[gatto (Stefano Gatto)]

Hello Markus,
yes, I tried with procedure you proposed before writing here
I definitely prefer not to reinstall from beta Iso, it’s a fresh install.
Maybe the repo I’m using is not so updated? It’s a VPS on OVH datacenter in France, can it be the problem?
Stefano

[gatto (Stefano Gatto)]

can a list of files in /usr/lib64/dovecot/ be useful to diagnose the problem?

the only file having an old date is the one is doing the problem, can I simply download a newer version of lib90_antispam_plugin.so from somewhere, or better from an official nethserver repo, and put it in the folder?
Stefano

[rmk (Reggie Ho)]

I check my version of lib90_antispam_plugin.so, it has the same date as yours… yet my NethServer is working at the moment…
In my case, my 7.5 server got updated with 7.6 beta files without my intention… then later
I updated the 7.5 server to 7.6 Beta using these line commands:

yum -y install http://packages.nethserver.org/nethserver/7.6.1810/updates/x86_64/Packages/nethserver-release-7-9.ns7.noarch.rpm

echo ‘7.6.1810’ > /etc/yum/vars/nsrelease

yum clean all
yum update
sudo reboot

Pls give it a try…

[gatto (Stefano Gatto)]

tried it with no luck :
yum -y install http://packages.nethserver.org/nethserver/7.6.1810/updates/x86_64/Packages/nethserver-release-7-9.ns7.noarch.rpm

Error: Nothing to do
yum clean all
yum update

rebooted with no changes in dovecot errors

[rmk (Reggie Ho)]

Can you try locking the Software update & reboot… see if that makes a difference…?

[gatto (Stefano Gatto)]

Did a reboot in the morning with software updates locked…

[rmk (Reggie Ho)]

I had a similar problem like yours when I tried and update another of a 7.5 version server to 7.6beta…even doing all the patches I did before didn’t solve the error.
…yes seems updating from 7.5 to 7.6 is not working…

I downloaded the 7.6beta2 ISO and install a new copy and restore the backup-config files and data…this seems to work ok… but in my new installation I don’t see or find the file lib90_antispam_plugin.so in the /usr/lib64/dovecot/ folder or in any other folder …

[gatto (Stefano Gatto)]

I didn’t want to reinstall from scratch but it looks like the only solution… well i don’t have to deliver that server until the end of this month, I just was hoping there was a better solution than format and restart…
ty Reggie

[rmk (Reggie Ho)]

Good luck…

[soscc (michael lausin)]

i made the mistake of installing the latest updates and now roundcube and imap are broken. i think it was asked before, is there a way to back out the last set of updates?

i looked at the software config page and it already says locked and Limit updates to repositories specific to version 7.6.1810 until the next system upgrade. do i need to do an unlock and do the config command and then relock so i can get the beta fixes?

do you know how soon before this oops is fixed in mainstream updates?

[mrmarkuz (Markus Neuberger)]

@soscc

i made the mistake of installing the latest updates and now roundcube and imap are broken.

It should have been fixed.

Does update from command line work without errors, maybe there’s a package missing?

yum update

A workaround, but as said it should have been fixed.

NethServer Imap problem

Run the following commands to disable the antispam plugin: mkdir -p /etc/e-smith/templates-custom/etc/dovecot/dovecot.conf/ touch /etc/e-smith/templates-custom/etc/dovecot/dovecot.conf/50spam_training expand-template /etc/dovecot/dovecot.conf systemctl stop dovecot.service systemctl start dovecot.service To undo: rm /etc/e-smith/templates-custom/etc/dovecot/dovecot.conf/50spam_training expand-template /etc/dovecot/dovecot.conf systemctl stop dovecot.service systemctl start dovecot.service

@soscc

i can get the beta fixes?

It’s always possible to install from command line. The “locked” setting only affects Software Center…

[soscc (michael lausin)]

i did the yum update, but there weren’s any updates for dovecot. i disabled the anti-spam and that worked! ty! when should i undo it or will the next update re-enable it?

[mrmarkuz (Markus Neuberger)]

Here’s the issue, please check if you have correct versions:

Rebuild or replace dovecot plugins

@soscc

i did the yum update, but there weren’s any updates for dovecot.

One of the nethserver-mail-* packages should fix it.

@soscc

when should i undo it or will the next update re-enable it?

No, it’s a custom template but you should try to make it work without the custom template.
You need to (re)move the custom templates to check if the system update works without the custom templates.

Did you try an unlocked update from Software Center recently? It should be updated to 7.6.1810 (final) and the issue should be fixed.
