hi, I needed to change ip address and then I used the command
/var/www/imscp/engine/setup/imscp-reconfigure --reconfigure primary_ip
During the procedure he returned the error in the title of the post, which also posted a screenshot.
[ERROR] main::setupDbTasks: Modules::ServerIP::add: Couldn't bring up the `enp2s0:1001' network interface: RTNETLINK answers: File exists at /var/www/imscp/engine/setup/../PerlLib/iMSCP/Provider/NetworkInterface/Debian.pm line 100.
...propagated at /var/www/imscp/engine/setup/../PerlLib/iMSCP/DbTasksProcessor.pm line 496.
Now the panel is not responding and I can not use imscp anymore, can you help me?
Thank you
