Secure boot is disabled
The installation stops before it is finished
The messages are

Got exactly the same problem!

After executing: sudo systemctl restart dlm, in dmesg:

[ 55.758759] PKCS#7 signature not signed with a trusted key
[ 55.758775] evdi: loading out-of-tree module taints kernel.
[ 55.758890] evdi: module verification failed: signature and/or required key missing - tainting kernel
[ 55.762943] evdi: [I] Initialising logging on level 5

@sharonshirley: this looks like a normal way the installation process ends. If things don't work, we'd need to get logs to be able to inspect what's happening.

@mkasprzyk: this seems different, in your case the kernel module signature verification fails. See https://stackoverflow.com/questions/...issing-taintin

Thanks
Michal

Same problem, installer always gets stuck at the 'Adding udev rule...' step

This is super frustrating, the amount of programming/debugging/plotting I have to do for work on a daily basis makes not being able to use two large screen monitors significantly hinders my productivity and accelerates my irritability.

also, @mlukaszek, no it isn't. Look at what your own website says a terminal for a successful install should look like: https://support.displaylink.com/know...rticles/684649

this is what the DLSupportTool gave me when I ran it: Attachment 3629
