    I have not checked my server or performed updates or other in a while and am now getting
    ERROR 500 - Internal Server Error!
    when I try to load a webpage. It also appears that I am not able to perform basic apt updates either.
    Debian 9.11 running NGINX
    [error] 11996#11996: *10070223 directory index of "/var/www/apps/" is forbidden

    Thanks for any and all help

    The error you posted is about the ispconfig apps vhost on port 8081 and not related to a website. Take a look at the error.log file of the website to find out why you get a 500 error when you access it.

    Which exact error message do you get when updating with apt?

    Might be that your server has mounted the filesystem in read-only mode due to errors. Did you reboot the server recently and was this the point the issues started?

    No I have not rebooted and was not doing anything on the server for some time. I do not have any type of cause and effect other than not keeping up with updates or other.

    According to the error messages, the hard disk is mounted read-only. This explains why services like php or system updates fail. Such a read-only remount happens e.g. when the harddisk failed and the filesystem got corrupted.

    Try to run these commands to see if the disk is writable:

    touch /var/cache/apt/test.txt
    ls -la /var/cache/apt/test.txt

    and post the result,

    The filesystem is mounted read-only indeed. Check the syslog file if you can find the reason why it got mounted in read-only mode. You might also want to check the filesystem for defects. To mount it in read-write mode later, you can use this command:

    mount -o remount, rw /

    Thanks for the reply.
    I contacted the host:
    "The server was still dropping into an emergency console at startup due to file system inconsistencies, however it was able to repair these issues after running fsck."
    everything now appears to be working.
    Thanks!
