I get an 'The network interface is unknown' error when upgrading from 1.2.9 to 1.2.17

Marcoo · Mar 27th 2016

Hi,

If I upgrade from 1.2.9 to 1.2.17 I get this error:

[ERROR] main::setupRebuildCustomerFiles:
Error while rebuilding customers files: [FATAL] iMSCP::Debug::__ANON__: The network interface is unknown at /var/www/imscp/engine/PerlLib/iMSCP/Provider/NetworkInterface.pm line 64

How can I fix it?

Ok, please execute the following query

SQL

# mysql -u root -p<your_sql_root_password>
> use imscp;
> UPDATE server_ips SET ip_card = 'eth0', ip_status = 'tochange';
> quit

Once done, rerun the i-MSCP installer.

If you have executed the SQL query above prior re-running the installer that should works. Can I access your server to debug?
