Ah, got it. Here is the unadulterated strace:
Offline
This doesn't work - google wants to open the thing in the browser instead of downloading it or whatever.
Please g/zip the file or something.
Offline
Try again, I changed the permissions.
Offline
This isn't a permission problem: It opens a new tab, loads a bit and then results in about:blank
If google tries to handle some hundred MB as text it'll likely just collaps and the download link is unfortunately no link but a javascript.
Offline
Firefox in troubleshooting mode has no problem downloading it and Falkon in normal mode also has no issues with it .
Both report preview not available and offer a button to download it.
Disliking systemd intensely, but not satisfied with alternatives so focusing on taming systemd.
clean chroot building not flexible enough ?
Try clean chroot manager by graysky
Offline
And did you click that button? Does something for some seconds and then nothing more.
(Maybe google is cascading experiments…)

It downloads a file called matlab.strace with a size of 47.4 Mib .
Try using https://drive.usercontent.google.com/do … t=download

Same… google starts loading but nothing happens and the connection breaks…
But I can actually wget it?!
Wtf google??

Just looking at it, the picard listing looks identical to what's in /usr/local/MATLAB/... . Not sure why it has two exactly mirror file systems, but I'll try that and see if that fixes things.
Also I appreciate the anonymity~
My browser is a firefox derivative, so that's why I was kinda confused about the issue you were having, thanks Lone Wolf for confirming.

Still failed, here's the new strace:
Offline
stat '/home/picard/.MathWorks/ServiceHost/-mw_shared_installs/v2025.12.1.2/bin/glnxa64/libgnutls.so.30'exists???
(Ftr, it's not the browser - it's either some conditional JS or the adblocker, admittedly didn't test w/o, or both or something entirely different. I'll look into that if it becomes a permanent problem. I cannot download https://drive.google.com/file/d/1ESNqDL … B4fQw/view either and that's just some kB)
Offline
The new strace does not go for /usr/lib/libgnutls.so.30 - did the error change?
Offline

So it's not failing because of gnutls (anymore)…
Skimming the strace - it links gdk-pixbuf2 ![]()
Try to downgrade that to https://archive.archlinux.org/packages/ … kg.tar.zst
(Isolated in /usr/local/MATLAB/R2025b/bin/glnxa64/libgdk_pixbuf-2.0.so.0 might do)
Can you run "matlab -webui"?
Offline
Run that before or after downgrading?
Offline
Either - ideally webui might sidestep the gdk-pixbuf2/glycin mess
Offline
I haven't downgraded, tried the webui and it still got the same error.
Offline
Downgraded gdk-pixbuf2, still got the following:
