Trouble Update Extension Manager (Updater Application Cron Script)

[contactbeed440]

Hi,
On Magento 2.3.5, I have a trouble when I want to update on of my extensions :

Error from Updater Application Cron Script:

"Found non-writable path(s):
/home/clients/c23a1ce266b3c2c1980db05fe75b5db6/ToGoWhere/.editorconfig
/home/clients/c23a1ce266b3c2c1980db05fe75b5db6/ToGoWhere/.github
/home/clients/c23a1ce266b3c2c1980db05fe75b5db6/ToGoWhere/.htaccess.sample
/home/clients/c23a1ce266b3c2c1980db05fe75b5db6/ToGoWhere/.php_cs.dist
/home/clients/c23a1ce266b3c2c1980db05fe75b5db6/ToGoWhere/.travis.yml.sample
/home/clients/c23a1ce266b3c2c1980db05fe75b5db6/ToGoWhere/.user.ini"

How can I fix it ???

In the same way, I can't to update status of new extension to install it in Extension Manager. Maybe, the same problem ???
My somebody have a suggestion ?

Many thanks for your help,

Ran the commands find . -type d -exec chmod 775 {} \; and find . -type f -exec chmod 664 {} \; and then chown -R www-data:www-data . All as SUDO and then flushed the cache and most of the readiness checks were solved except for three supposed .sample files in the main directory which did not even exist. You can try to create files and ran the codes above again and now the readiness check works
