Mailman 2.0.1 update failure

Updating Mailman from 2.0.0 to 2.0.1 fails with

Code

Plugin::Mailman::_execMailmanCmd: Couldn't set EGID: Invalid argument at /var/www/imscp/gui/plugins/Mailman/backend/Mailman.pm line 446.

Imscp 1.4.3 on Ubuntu 16.04.2 LTS (GNU/Linux 4.4.0-79-generic x86_64)

Please look into this. If you any additional information just let me know.
Thanks,
Jann

Please, result of the following commands:

getent group list
getent passwd vu2000
getent group vu2000
grep 'IMSCP_GROUP' /etc/imscp/imscp.conf
grep 'SYSTEM_USER_PREFIX' /etc/imscp/imscp.conf
grep 'SYSTEM_USER_MIN_UID' /etc/imscp/imscp.conf

**cynric** · Jun 20th 2017

Sure:

list:x:38:vu2000
vu2000:x:1001:1001:i-MSCP Master Web User:/var/www/imscp/gui:/bin/false
vu2000:x:1001:www-data
IMSCP_GROUP = imscp
SYSTEM_USER_PREFIX = vu
SYSTEM_USER_MIN_UID = 2000

Thanks,
Jann

Thanks.

Did you tried a retry through the plugin management interface?
Could it be possible to access your server for investigation?

Confirmed under Ubuntu 16.04 (doesn't occur under Debian Jessie):

I'll investigate and fix.

Ok, thank you Laurent!
Tried dist-upgrading and updated to I-mscp 1.4.6 in the meantime, but of course retrying still fails.

@cynric

It seem that under Ubuntu, an error is raised when you attemps to localize EGID variable:

Works under Debian Jessie

Perl

{
local $!;
local $) = '38 1001 1001';
die( sprintf( "Couldn't set EGID: %s", $! ) ) if $!;
}

but raise an error under Ubuntu 16.04... Thus, I'll revert back to SU(1) usage

**Nuxwin** · Jun 20th 2017

Hmm. But under Ubuntu 16.04, following is working...

Perl

{
local $!;
local $EGID = '38 1001 1001';
die( sprintf( "Couldn't set EGID: %s", $! ) ) if $!;
}

$EGID is a alias of $) ... Incredible...

The bug should be fixed in latest version. See Mailman plugin v2.0.2 RELEASED

Thanks you for your report.
