**The issue I am facing:**
pihole-FTL not starting after update
**Details about my system:**
VMware virtual machine running centos 8.5 (just upgraded from 7)
**What I have changed since installing Pi-hole:**
Went to update Pihole, and was told I needed to upgrade the base OS first. Upgraded centos from 7 to 8.5, then updated pihole and now it shows the following at the end of the update:
[i] Installing latest logrotate script...
[i] Existing logrotate file found. No changes made.
[i] Backing up /etc/dnsmasq.conf to /etc/dnsmasq.conf.old
[✓] man pages installed and database updated
[i] Testing if systemd-resolved is enabled
[i] Systemd-resolved is not enabled
[✓] Restarting lighttpd service...
[✓] Enabling lighttpd service to start on reboot...
[i] Restarting services...
[✓] Enabling pihole-FTL service to start on reboot...
[i] Restarting pihole-FTL service...
Unable to complete update, please contact Pi-hole Support

Your debug log shows:
```auto

This is an old version of the library and recent Operating Systems usually use a newer version, but I don't know if Centos 8 has the correct library.
Maybe you can find a solution reading other comments:

Awesome - require an OS that doesnt even support the correct libraries.... _sigh_ and people wonder why I never update my crap.
Looks like its likely time to wipe it clean and start over with a different base OS......

Pi-hole supports Centos Stream 8.
Centos 8 is not supported anymore by Centos/Red Hat.
You can try the docker image.
