I was able to get passed "ERROR: Error Information: Maya 2026 : [IDSDK] 3073: The PC has not installed WebKitGTK yet, please install WebKitGTK." By doing the following, very similar solution to @jimmy_christensenMSURY.
sudo apt install rpm
cat > ~/mk_webkit2gtk3_dummy.sh <<'Bash'
#!/bin/bash
set -e
cat > webkit2gtk3.spec <<'SPEC'

bash ~/mk_webkit2gtk3_dummy.sh
Now I'm getting the below window but no browser window opens up.

At first I couldn't get a browser window to open. I restarted my machine and it worked, I assume that there is an easier way but it worked and a browser opened and I was able to authenticate through Autodesk. Then I ran into this issue:

In order to register AdskIdentityManager so that Ubuntu would recognize it as an app I did this:
/opt/Autodesk/AdskIdentityManager/Current/AdskIdentityManager --register
I noted that the file it created in ~/.local/share/applications/com.autodesk.AdskIdentityManager.desktop had the AdskIdentityManager's version number in the path instead of "Current" so I updated that file to future proof it.
Then I updated the database and set adskidmgr as the default app:
# make sure the desktop database picks up the new entry
update-desktop-database ~/.local/share/applications
# set it as the default for this scheme
xdg-mime default com.autodesk.AdskIdentityManager.desktop x-scheme-handler/adskidmgr
And now Maya 2026 works on Ubuntu 24.10
Seems like there are still a few little quirks like complaining about not having access to the internet:

There are also some new errors I don't recall seeing on Maya 2024, here's my startup output:
Detected locale "C" with character encoding "ANSI_X3.4-1968", which is not UTF-8.
Qt depends on a UTF-8 locale, and has switched to "C.UTF-8" instead.
If this causes problems, reconfigure your locale. See the locale(1) manual

Running these two lines fixed the permissions issue, it's just me on this machine:
sudo mkdir -p /var/lib/Autodesk/CER
sudo chown -R $USER:$USER /var/lib/Autodesk
And I removed "LC_ALL=C" from my Maya.env and that fixed the "UTF-8" issues.
I then created a fresh account to be to see what the default Maya.env looked like and it was empty. I removed everything from my Maya.env and Maya starts fine without any extra complaints. The entries must have been carried over from a previous Maya version.
