Originally created by @JanPauw on GitHub (Jan 30, 2025).
✅ Have you read and understood the above guidelines?

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

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

📝 Provide a clear and concise description of the issue.
Time of writing 19:27 UTC
I am trying to create a new Ubuntu LXC creating the script straight from the website.
I can enter all the values with no problem, but after the "input" part is done and it starts to create the lxc, I run into a script issue:
"unable to create CT 201 - command 'lxc-usernsexec -m u:0:100000:65536 -m g:0:100000:65536 -- tar xpf - --zstd --totals --one-file-system -p --sparse --numeric-owner --acls --xattrs '--xattrs-include=user.' '--xattrs-include=security.capability' '--warning=no-file-ignored' '--warning=no-xattr-write' -C /var/lib/lxc/201/rootfs --skip-old-files --anchored --exclude './dev/'' failed: exit code 2
bash: line 201: exit: A problem occured while trying to create container.: numeric argument required
/dev/fd/63: line 840: failed: unbound variable"
I see that the "build.func" was updated 28 minutes ago:
"
72335f2c4e"Do the scripts get cached locally somewhere that I can clear?
⚙️ What settings are you using?
🖥️ Which Linux distribution are you using?
Debian 12
🔄 Steps to reproduce the issue.
Step 1: Open node shell.
Step 2: Paste the script: " bash -c "$(wget -qLO - https://github.com/community-scripts/ProxmoxVE/raw/main/ct/ubuntu.sh)" "
Step 3: Go through Default/Advanced settings.
Step 4: Select 'Yes' to create lxc.
Step 5: Get error.
❌ Paste the full error output (if available).

@michelroegl-brunner commented on GitHub (Jan 30, 2025):
You always have the same ct id? the latest chage has nothing to do with it, as lxc get created every minute as i see. The command is failing on your proxmox node somehow. can you restart it?
@JanPauw commented on GitHub (Jan 30, 2025):
Sure I will restart, and also try again with a different CT ID.
@MickLesk commented on GitHub (Jan 30, 2025):
Its an template issue, maybe orphaned lvm's or cracked old config (or an VM with the Same ID)
@JanPauw commented on GitHub (Jan 30, 2025):
Restarted and used a different CT ID:

Your subui is broken on your node
nano /etc/subuid and /etc/subgid both need to contain root:100000:65536
@JanPauw commented on GitHub (Jan 30, 2025):
Checked those files, and ran the Default Installation, I apologise for the formatiing at the end.
Looks like the failure breaks my cli formatting. I used "cat /etc/subuid" & "cat /etc/subgid":

Thanks, will try that, I appreciate your time and help :)
@MickLesk commented on GitHub (Jan 30, 2025):
Other Scripts doesnt Work too?
@JanPauw commented on GitHub (Jan 30, 2025):
Other scripts worked fine, but they are all debian based, this is the frist time I wanted to try ubuntu lxc.
But I have deleted the "ubuntu-24.04-standard_24.04-2_amd64.tar.zst" from "/var/lib/vz/template/cache/" and the script ran fine.
