Answer 1

The issue about of file does not give write permission so run bellow command in Magento root directory:

chmod -R 777 .github
chmod -R 777 pub var generated

Answer 2

The issue happens because of the ownership is not right at your system.

The user (like apache) from where your add your cronjob, does not have write & read issue. So, you have to provide that user to the right access to run cron job and that user must have the permission of access like Web user access & permission.

Example:

Suppose, you have web user apache i.e www-data and you can run cronjob from that www-data, then try below code:

sudo crontab -u www-data php bin/magento cron:install --force
