It's a slightly different error now.

It's no longer "Error in Line 33" but "Error in Line 48".

The second error, "Error in Line 1346", is the same as before.

@M-G-86 commented on GitHub (Nov 18, 2025): It's a slightly different error now. It's no longer "Error in Line 33" but "Error in Line 48". The second error, "Error in Line 1346", is the same as before. -------------------------------------- __ __ / //_/___ __________ ___ / ,< / __ `/ ___/ __ `__ \ / /| / /_/ (__ ) / / / / / /_/ |_\__,_/____/_/ /_/ /_/ ⚙️ Using Default Settings on node proxmoxdmz (🔍 Verbose) 🆔 Container ID: 104 🖥️ Operating System: debian (13) 📦 Container Type: Privileged 💾 Disk Size: 30 GB 🧠 CPU Cores: 2 🛠️ RAM Size: 8192 MiB 🔍 Verbose Mode: Enabled 🚀 Creating a Kasm LXC using the above default settings ✔️ Storage vms (Free: 44.8GB Used: 70.6GB) [Template] ✔️ Storage vms (Free: 44.8GB Used: 70.6GB) [Container] ✔️ Cluster is quorate ✔️ Template debian-13-standard_13.1-2_amd64.tar.zst [local] ✔️ LXC Container 104 was successfully created. ⚙️ Configuring VAAPI passthrough for LXC container ℹ️ VAAPI enables GPU hardware acceleration (e.g., for video transcoding in Jellyfin or Plex). ➤ Automatically mount all available VAAPI devices?

@MickLesk they do have a github ^^

https://github.com/kasmtech/KasmVNC/ you can also reach them on reddit, they are quite "active".

Funny, for me the version extraction logic used here is working just fine, e.g. downloading the normal release and not service images.

EDIT: my initial though was correct, they seem to have replaced the main URL with a hubspot analytics url, so we can't fetch that, or we change it to match first hubspot URL, then our script just detects the first release url which is therefore only second latest version (1.18.0 instead of 1.18.1)
