    The error that the indexer namespace is missing can be related to a previous error when installing dependencies or setting the configurations. Maybe recheck previous commands you executed. Otherwise, check if you can set up a local magento system and check if you can reproduce the problem.

Please mention your Magento Version first.

An exception was raised while creating "Request"; no instance returned

Your First error is coming due to most likely not changing php version properly, you should only use PHP version 7.2 when you're working on Magento 2.3.x

Change PHP version according to your Magento version, refer below link if you're using Magento 2.3.x

https://devdocs.magento.com/guides/v2.3/install-gde/system-requirements-tech.html

Try below commands for changing PHP version

sudo a2dismod php7.0
sudo a2enmod php7.2
sudo service apache2 restart
sudo update-alternatives --set php /usr/bin/php7.2

Also refer this link for similar issue

About your second error regarding 7.2 version,

Try to give permission first to your Magento Directory

sudo chmod -R 777 magentoDir

then use your upgrade-deploy commands.

if that doesn't help try to find solution in below link.

    Yes it is Version Error, also when i change my php version to 7.2 all commands are run normally. But when start admin panel with php changed version 7.2 , My admin panel was to working. so always i change my php version and apply all these commands and again change version to 7.3. after that i found a short way to apply my commands without change version is:- /usr/bin/php7.2 bin/magento indexer:reindex so if you have anny suggestion for this please give me Thanks
