Setting up Container OS Fails with [ERROR] in line 90: exit code 0

[Enn0]

Trying to install pi-hole LXC from bash -c "$(wget -qLO - https://github.com/tteck/Proxmox/raw/main/ct/pihole.sh)" .
Every time I do, I encounter the same error:

✓ Updated LXC Template List
✓ LXC Container 100 was successfully created.
✓ Started LXC Container
/ Setting up Container OS
[ERROR] in line 90: exit code 0: while executing command locale_line=$(grep -v '^#' /etc/locale.gen | grep -E '^[a-zA-Z]' | awk '{print $1}' | head -n 1)

I found a reference to this line here:

Proxmox/misc/install.func

Line 90 in d073535

locale_line=$(grep -v '^#' /etc/locale.gen | grep -E '^[a-zA-Z]' | awk '{print $1}' | head -n 1)

but am still clueless as to what exactly is going wrong, or how to fix it.

So hopefully someone here can point me in the right direction?

I appaear to have the same issue installing ANY LCX through the helper scripts here. :/

From inside the LCX container:

root@pihole:~# 
root@pihole:~# echo $locale_line

root@pihole:~# locale_line=$(grep -v '^#' /etc/locale.gen | grep -E '^[a-zA-Z]' | awk '{print $1}' | head -n 1)
root@pihole:~# echo $locale_line

root@pihole:~# 

When I do this on the PVE host I get en_US.UTF-8.

Manually downloading and installing pi-hole from inside the error'ed container...

(wget -O basic-install.sh https://install.pi-hole.net
sudo bash basic-install.sh)

... works just fine.

I ttried both through SSH session and GUI shell on PVE itself. Same result.
