ty for your guide, i successfully installed pi-hole on my syno.
But i have a problem: every time i use the web admin page warn me about a available update.
I try to re-install or pihole -up but the warn still exist..
any tips? ty
edit: pihole -v:
::: Pi-hole version is (Latest version is v2.9.4a)
::: Web-Admin version is (Latest version is v220.127.116.11a)
ok found the solution: From /etc/.pihole do a git pull
