Having trouble installing on Debian 12 LXC on Proxmox

I am having trouble installing a new instance of urbackup on a Proxmox LXC Debian 12 container. I’m using the proxmox helper script:
bash -c “$(curl -fsSL https://raw.githubusercontent.com/community-scripts/ProxmoxVE/main/ct/urbackupserver.sh)”
It doesn’t seem to be a helper script issue but rather a repository problem.

Here is the error output:
E: Failed to fetch https://slc-mirror.opensuse.org/repositories/home%3A/uroni/Debian_12/amd64/urbackup-server_2.5.33.0-1_amd64.deb File has unexpected size (4377736 != 4378348). Mirror sync in progress? [IP: 195.135.220.50 443]

I’ve tried over the past week thinking it might be a mirror issue and would be fixed. I thought I’d see if it is a known problem. Thanks for any guidance.

FYI, I wound up downloading the binary and installing manually in the LXC. It is all working fine but I hope this is resolved. I’ll of course keep watching. Thanks in advance.
