Alpine Docker script hangs on "Internet NOT Connected" - ISP blocks outbound ping

[Yakrel]

✅ Have you read and understood the above guidelines?

yes

📜 What is the name of the script you are using?

alpine-docker

📂 What was the exact command used to execute the script?

bash -c "$(curl -fsSL https://raw.githubusercontent.com/community-scripts/ProxmoxVE/main/ct/alpine-docker.sh)"

⚙️ What settings are you using?

• Default Settings

🖥️ Which Linux distribution are you using?

Debian 12

📝 Provide a clear and concise description of the issue.

The Alpine Docker script hangs indefinitely after showing "Internet NOT Connected" message without prompting to continue anyway. When I click enter it just throws and error and kicks me out of setup

I think scripts checks the internet connection by pinging and IP adress and because my ISP somehow blocked outgoing PING requests it cant detect the internet connection.

Environment:

• Proxmox VE host with functional internet connectivity
• ISP blocks outbound ping requests to external IPs (8.8.8.8, 1.1.1.1, etc.)
• Local network connectivity works fine (can ping gateway 192.168.1.1)

Issue:
Script performs internet connectivity check via ping, fails due to ISP restrictions, and hangs without offering "Would you like to continue anyway? <y/N>"
prompt.

🔄 Steps to reproduce the issue.

I just run script then select first option using default settings.

❌ Paste the full error output (if available).

I think scripts should ask if I want to continue anyway Y/N but looks like this feature is not implemented on this script.

try with alpine-script in VED as default please - there is an newer version of spinner & background logic. Its the same?

bash -c "$(curl -fsSL https://raw.githubusercontent.com/community-scripts/ProxmoxVED/main/ct/alpine.sh)"

this one worked without problem, I was able to see continue anyway prompt, though what I was testing was alpine LXC with docker this one is Alpine lxc only

TY Also I know another issue must be created for it but, when you first run alpine docker script select advanced and create config file with it and after that when you try to install with that config file there is at least 3 variables are(TUN,IPV6 I dont remember all) missing and should be added manually to config file, FYI TY 👍
