typo3 scheduler works only manually

Question

I have some problems with the scheduler of typo3 9.5.5. I already set up a few jobs (e.g. ke_seach indexing every 2 mins) and they do work if I start them manually. But the automatic execution does not work. The backend module just shows "late" and nothing else happens.

It seems that there is also nothing in the logs. The backend user "_cli_scheduler" was created (first without and currently with admin rigths) but this user never gets a login.

System: Typo3 9.5.5 on a virtual machine (Centos 7). The webserver is a xampp/lampp package running as localhost/

.htaccess (if necessary):

#####
#
# Example .htaccess file for TYPO3 CMS - for use with Apache Webserver
#
# This file includes settings for the following configuration options:
#
# - Compression
# - Caching
# - MIME types
# - Cross Origin requests
# - Rewriting and Access
# - Miscellaneous
# - PHP optimisation
#
# If you want to use it, you have to copy it to the root folder of your TYPO3 installation (if its
# not there already) and rename it to '.htaccess'. To make .htaccess files work, you might need to
# adjust the 'AllowOverride' directive in your Apache configuration file.
#
# IMPORTANT: You may need to change this file depending on your TYPO3 installation!
#            Consider adding this file's content to your webserver's configuration directly for speed improvement
#
# Lots of the options are taken from https://github.com/h5bp/html5-boilerplate/blob/master/dist/.htaccess

### Begin: Compression ###

# Compressing resource files will save bandwidth and so improve loading speed especially for users
# with slower internet connections. TYPO3 can compress the .js and .css files for you.
# *) Uncomment the following lines and
# *) Set $GLOBALS['TYPO3_CONF_VARS']['BE']['compressionLevel'] = 9 for the Backend
# *) Set $GLOBALS['TYPO3_CONF_VARS']['FE']['compressionLevel'] = 9 together with the TypoScript properties
#    config.compressJs and config.compressCss for GZIP compression of Frontend JS and CSS files.

Can you please confirm, that you have set up a cronjob to execute the scheduler? See documentation for further details. – Michael

Exactly this was the problem, so the following steps solved the problem:

sudo crontab -e

This opened vim and after pressing "i" the following line was inserted:

*/6 * * * * /opt/lampp/bin/php /opt/lampp/htdocs/typo3/sysext/core/bin/typo3 scheduler:run

After save and exit ([Esc], :x [Enter]) finally the cron daemon was restartet:

sudo systemctl restart crond.service

Everything works now.

I made this post because it seems to be not possible to mark a comment as a solution. Thanks everyone for (really quick) help.
