Error creating new container

I have a problem when creating a new container with Debian 10.2

The following error appears
Detected container architecture: amd64
TASK ERROR: unsupported debian version '10.2'
I already modified file ( /usr/share/perl5/PVE/LXC/Setup/ ) with this content :
sub new {
my ($class, $conf, $rootdir) = @_;

my $version = PVE::Tools::file_read_firstline("$rootdir/etc/debian_version");

die "unable to read version info\n" if !defined($version);

# translate testing version names
$version = 9.1 if $version eq 'stretch/sid';
$version = 10 if $version eq 'buster/sid';
$version = 10 if $version eq '10.2';

die "unable to parse version info '$version'\n"
if $version !~ m/^(\d+(\.\d+)?)(\.\d+)?/;

$version = $1;

die "unsupported Debian version '$version'\n"
if !($version >= 4 && $version <= 11);

my $self = { conf => $conf, rootdir => $rootdir, version => $version };

$conf->{ostype} = "debian";

return bless $self, $class;
As you can see the error message doesn't corresponds to the one describe in the Perl file. I don't know how to force the file update.
Is it possible that another file is used?

I'm running Proxmox 5.2 :

Do I need to restart some service after updating the file?

I already did this operation one another host with success, but I can't remember if I did something particular.

I'm running Proxmox 5.2 :
5.2 is EOL and isn't supported anymore, for running newer guest CTs, getting security and other bug fixes upgrade at least to 5.4 ASAP - but also note that the 5.4 will go EOL at the end of July!
Ensure you have valid Proxmox VE repository you can access setup

After you upgraded to 5.4 please make plan an upgrade to latest 6.x soon.

thats the issue, you run a totally outdated version.

just update to latest 5.4 or even better, to the current release 6.2.
