Calamares crashes near 40% because of a script issue in /user/lib…
Please look for a correction. We don’t have the previous one and the testing one is too old.
Here’s the crash error:
Main script file /usr/lib/x86_64-linux-gnu/calamares/modules/networkcfg/main.py for python job networkcfg raised an exception.
Same issue with, btrfs, xfs, ext4, online, offline and/or secure boot enabled or not. Dual boot with Arch [kde-unstable].
Same for me - using the latest unstable ISO (25022024)
The same problem here. User version 20240226
That makes sense, because it seems to be a network thing.
Did you guys try with AND without internet connection activated while installing?
(I guess mostly relevant if using wifi)
My install attempt was with a wired internet connection.
In the end I used an ISO from January and just updated this.
The bug is in the main.py file. Editing the file as follow allows Calamares to complete the install (neon-Unstable 20240225_ISO).
The bug is also in the latest neon-Testing ISO.
Before launching the install edit the main.py file. Save, exit and run Calamares after.

I’m using ISO 0240303-0009 and I’m going in an infinite loop …
My understanding is that I need to boot from the iso and then run “install system” which appears in the top left corner of the GUI.
But before I do, I need to open main.py and amend it as you say. All good.
I’ve found the right file and edited it - but the install still fails in the same place.
It seems that main.py is being ovewritten - but I don’t know from where?
Is there another way of doing this?
I see this in neon-user-20240303-0009. I see a fix has been posted in this thread, but has a bug report been made?
I have copied the complete “networkcfg” folder from a working version.
I delete the original folder and replace it with the working one.
that’s interesting Rolf_Traumer - how are you installing? using the iso burned to a USB stick? Can you say a bit more about your method please?
I start the ISO via USB stick on Ventoy.
When neon is running, I exchange the file and install the OS as usual.
thank you Rolf_Traumer! I never heard of Ventoy, I’ve used it to create the usb again.
I must be doing something really silly - I replaced the main.py file in the /usr/lib… with the amended file.
Just in case, here’s the code that’s in main.py now:
# Also install netplan files
source_netplan = "/etc/netplan"
root_mount_point = libcalamares.globalstorage.value("rootMountPoint")
target_netplan = os.path.join(root_mount_point, source_netplan.lstrip('/'))
if os.path.exists(source_netplan) and os.path.exists(target_netplan):
for cfg in glob.glob(os.path.join(source_netplan, “90-NM-*”)):
source_cfg = os.path.join(source_netplan, cfg)
target_cfg = os.path.join(target_netplan, os.path.basename(cfg))
if os.path.exists(target_cfg):
continue
shutil.copy(source_cfg, target_cfg)
But I’m still getting the error:

I modified the file, set it immutable and it still was overridden and failed that same way. ?
I have the same with the 20240229 version I just downloaded. Please let me know when this is fixed at the source.
Trying to download that just gets spam, pop ups, and virus warnings.
Sorry, I uploaded the file to a filehoster.
No warning was displayed for me.
I have deleted the link as a precaution.
Understood! Can you upload somewhere else, and tell us how you use it?
Hi, same problem here with neon-user-20240303-0009 as well as neon-testing-20240227-0254
The fix above didn’t work for me. Put a report up on bugs.kde.org
I think this is the original file:
I also found this bugreport, that is closed with a commit, so if you guys just wait it will most likely be fixed in a new release.
