recently my pihole5 was having issues where i would get the 403 error both on pi.hole and the ip/admin...
I tried to repair it as im running on a raspberry pi 4 with linux 10.
Ran sudo pihole -up and read the following message and silly enough i ran it.
f you are seeing this message after having run pihole -up:
sudo PIHOLE_SKIP_OS_CHECK=true pihole -r
to my surprise it upgraded
pi@pi4:~ $ pihole version
Core version is v6.0.1 (Latest: v6.0.3)
Web version is v6.0 (Latest: v6.0.1)
FTL version is v6.0.1 (Latest: v6.0.1)
the web interface looks like the new one but is still showing that it requires and update
My recommendation - yes. Your Pi OS is quite out of date.
Yes, but not an update. You will need a clean Pi-hole install on the new OS, since you typically erase the uSD card for a fresh OS install. You can save your existing Pi-hole settings with the teleporter function and reimport them to the new install.
