we cannot update our extension list on typo3 8.7.x on Ubuntu 16.04.6 LTS there is no error message in apache error.log, an we cannot see any reason for this.
do you have any hints for us?
after updating /etc/php/7.2/apache2/php.ini with a new cacert file openssl.cafile= /etc/php/7.2/apache2/cacert.pem
its working.
