In app/code/local/Info/News/Block/Adminhtml/News.php, you should declare __construct() method (it contains 2 underscores) instead of _construct() method (it contain 1 underscore).

<?php
class Info_News_Block_Adminhtml_News extends Mage_Adminhtml_Block_Widget_Grid_Container {
    public function __construct (){
       
        $this->_controller = 'adminhtml_news';
        $this->_blockGroup = 'news';
        $this->_headerText = Mage::helper('news')->__("Manage News");
        parent::__construct();
    }
}

Updated: Found your issues:

Your app/code/local/Info/News/etc/config.xml file has incorrect config. Xml nodes value for version, models, and resources must not contain any space nor new line.

And because Mysql4 classes are deprecated, you should use Resource classes instead (It does not relate to your issue: can't get model).

The implementation:

Step 1: In app/code/local/Info/News/etc/config.xml:

Change version tag to <version>0.0.1</version>.
Change your code for models tag to the following:

<models>
    <news>
        <class>Info_News_Model</class>
        <resourceModel>news_resource</resourceModel>
    </news>
    <news_resource>
        <class>Info_News_Model_Resource</class>
        <entities>
            <news>
                <table>info_news</table>
            </news>
        </entities>
    </news_resource>
</models>

Change your code for resource to the following:

<resources>
    <news_setup>
        <setup>
            <module>Info_News</module>
        </setup>
    </news_setup>
    <news_write>
        <connection>
            <use>core_write</use>
        </connection>
    </news_write>
    <news_read>
        <connection>
            <use>core_read</use>
        </connection>
    </news_read>
</resources>

Finally, your app/code/local/Info/News/etc/config.xml should be changed like the following:

<config>
    <modules>
        <Info_News>
            <version>0.0.1</version>
        </Info_News>
    </modules>
    <admin>
        <routers>
            <news>
                <use>admin</use>
                <args>
                    <module>Info_News</module>
                    <frontName>admin_news</frontName>
                </args>
            </news>
        </routers>
    </admin>
    <adminhtml>
        <layout>
            <updates>
                <news>
                    <file>info/news.xml</file>
                </news>
            </updates>
        </layout>
    </adminhtml>
    <global>
        <models>
            <news>
                <class>Info_News_Model</class>
                <resourceModel>news_resource</resourceModel>
            </news>
            <news_resource>
                <class>Info_News_Model_Resource</class>
                <entities>
                    <news>
                        <table>info_news</table>
                    </news>
                </entities>
            </news_resource>
        </models>
        <helpers>
            <news>
                <class>Info_News_Helper</class>
            </news>
        </helpers>
        <blocks>
            <news>
                <class>Info_News_Block</class>
            </news>
        </blocks>
        <resources>
            <news_setup>
                <setup>
                    <module>Info_News</module>
                </setup>
            </news_setup>
            <news_write>
                <connection>
                    <use>core_write</use>
                </connection>
            </news_write>
            <news_read>
                <connection>
                    <use>core_read</use>
                </connection>
            </news_read>
        </resources>
    </global>
</config>

Step 2: Remove app/code/local/Info/News/Model/Mysql4 folder.

Step 3: Create app/code/local/Info/News/Model/Resource/News.php file

<?php

class Info_News_Model_Resource_News extends Mage_Core_Model_Resource_Db_Abstract
{
    protected function _construct() {
        $this->_init('news/news','news_id');
    }
}

Step 4: Create app/code/local/Info/News/Model/Resource/News/Collection.php file

<?php

class Info_News_Model_Resource_News_Collection extends Mage_Core_Model_Resource_Db_Collection_Abstract
{
    public function _construct() {
        $this->_init('news/news');
    }
}

Done, now you can go the admin to see result.

Let's change $this->setId('newsGridView'); to $this->setId('newsGrid'); in app/code/local/Info/news/Bock/Adminhtml/News/Grid.php and update app/code/local/Info/News/Block/Adminhtml/News.php file as my updated answer and clear the cache. — Tu Van, Commented Nov 17, 2022 at 16:42
And <layout version="0.0.1"> should be changed to <layout version="0.1.0"> in app/design/adminhtml/default/default/layout/info/news.xml — Tu Van, Commented Nov 17, 2022 at 17:38
I did all your suggestions, but still not working I can't progress since last Friday, please help — abderrahim rida, Commented Nov 17, 2022 at 19:59
Let's zip your module and upload somewhere then send the link here, I'll check. — Tu Van, Commented Nov 17, 2022 at 20:35

I think error comes from router and/or layout file.

rename install script to install-0.0.1.php
set path in adminhtml.xml to <action>adminhtml/news/index</action>
in block classes use _construct() (one underscore)

class Info_News_Model_Resource_News_Collection extends Mage_Core_Model_Resource_Db_Collection_Abstract

@sv3n his router works fine, don't need to fix. I'll write more detail after answer you question in my answer. — Tu Van, Commented Nov 20, 2022 at 14:51
The config router in the original poster will get URL: base_url/admin/news/index while the config router as your share is base_url/adminhtml/news/index — Tu Van, Commented Nov 20, 2022 at 15:35
@abderrahimrida you should update the router as sv3n advised to make your code safe. "Magento released Security Patch SUPEE 6788 on Oct 27, 2015, to ensure protection against threats such as remote code execution, information leaks, and cross-site scripting." — Tu Van, Commented Nov 21, 2022 at 1:55
