spawn-fcgi stopped working on Ubunru 18, why?

Question

Perl

On ubuntu 16, Munin worked perfectly and drew all the graphs,
now I crawled to ubuntu 18
, Munin set it up, but as in ubuntu 16, spawn-fcgi did not start and crashes before it even starts, (it draws large pictures of graphs)
The team that worked on ubuntu 16

spawn-fcgi -s /var/run/munin/fcgi-graph.sock -U www-data -u www-data -g www-data /usr/lib/munin/cgi/munin-cgi-graph

Console output

:~# spawn-fcgi -s /var/run/munin/fcgi-graph.sock -U www-data -u www-data -g www-data /usr/lib/munin/cgi/munin-cgi-graph
spawn-fcgi: child exited with: 2

Tell me pliz where to dig?

#define EPERM 1 /* Operation not permitted */
#define ENOENT 2 /* No such file or directory */
check that /usr/lib/munin/ cgi/munin-cgi-graph is

file /usr/lib/munin/cgi/munin-cgi-graph
/usr/lib/munin/cgi/munin-cgi-graph: Perl script text executable

and run
