Changing the scripts ownership to your user doesn't give the script the rights to install on the system try this instead:

sudo ./install.sh

It will ask for your password. It should install then but if not, copy any error messages and post them back here.

Thanks, I thought I'd tried that too. Just so I'm 100% clear where to do this, open Konsole, CD to the location of the install.sh then run sudo ./install.sh or just run the sudo xyz directly in the Konsole?

I think the issue I had was CD'ing to the Downloads folder. I'd extracted the compressed folder there but CD'ing to /Downloads kept returning a "no such folder" error. IIs the Downloads folder somehow protected so I need to move files out (eg to desktop) to use them?

Yes, /Downloads does not exist, normally. That would be a directory at your top level (aka '"root")
You'd need to cd to the full path, , but where you are currently has a bearing as well so

Code:

cd /home/username/Downloads

is the longest way to do it.

A helpful shortcut for /home/username is ~, so:

Code:

cd ~/Downloads

or if you are already in ~ (very likley if you have just opened Konsole), then

Code:

cd Downloads

-- note there is no slash

Another trick is to navigate to the directory in Dolphin and hit F4 to open a terminal panel, then run the command.

Thanks claydoh that's really helpful, it didn't occur that Downloads didn't exist in the sense of a regular folder. I'll have a go later. 25 years of Windows learning doesn't get you very far in Linux it would appear

You'll get there. This is a good start - asking questions here and other places, like r/Kubuntu. You'll usually get a more "refined" answer here because we all use Kubuntu vs. places like Reddit, Stack Exchange, etc., but it doesn't hurt to search those places too.

Do yourself (and us) a favor and when you post, use "Object & Deviation" type posts and give as many relevant details as you can. "Object" is basically the thing that's wrong and "Deviation" is what is wrong. Fill in as many details as you can, list what you've tried, report exact error messages when you can. Following a "what, where, when, to what extent" may help you put down the needed info and lead to a quicker response.

As far as this comment: "Downloads didn't exist in the sense of a regular folder" can you explain what you meant? "Downloads" certainly is a folder but it exists in your home folder as Claydoh explained.

To drill down a bit more, when using the terminal, the file hierarchy starts at "/" (no drive letters like Windows) so when you you put the slash in front of Downloads you said "start the the top and look for the Downloads folder." Which obviously doesn't exist so you got the error.

You can either use an "implied" path or full path. The full path in this case, as was explain, is "/home/<username>/Downloads". An implied path, is like "start when I am and go from here." So if you are already in "/home/<username>/" then "Downloads/" is the implied path. There's lots more, but I'll stop there.

Here's a tip: If you need to access the terminal you can very quickly get where you want by using Dolphin (the file manager), navigate to whatever folder you need to be in, then press F4. This will open a terminal pane where you are at the bottom of the Dolphin window. The path will even show in the terminal prompt next to your name and hostname like this " name@hostname:~/Downloads" so you can verify you're in the right location. Pressing F4 again closes the terminal pane.

Thanks oshunluvr, I'll try to be more verbose.

Object: to install a driver for an MSI AXE5400 UBS dongle. The Linux driver is available on their site.
Deviation: running the install.sh results in errors: compile make driver error: 127 and then error 2.

Efforts:
I have run lsusb which shows the adapter connected:
Bus 001 Device 003: ID 0db0:991d Micro Star International 802.11ax WLAN Adapter

In the folder with the install.sh (and supporting files) I have made it executable with sudo permission. Executing it was generating a compile make driver error: 127 so I have run sudo apt install build-essential which seemed to move things along and now I have Compile make driver error: 2

Some more research tells me that Linux simply doesn't support the RTL8852C chipset in the MSI AXE5400 dongle so it seems all the above might just be in vain anyway and I'll need to either revert to a Window setup somehow or buy another wifi dongle. I've used an old TP Link nano which worked straight away but is very slow at ~230Mb but at least it works.

My comment about the Downloads folder not being accessible is perhaps a misunderstanding from my Window experience where the DL folder is wherever you want and has no special permissions. It is there but as you can see I get an error CDing to it:

thanks
Paul

Excellent job detailing your efforts. Too bad it was in vain.

I see this on the MSi driver page:

Description:
First release for Linux Driver Version: v1.19.2-107-g2751ef875.20221230 (kernel 3.13 ~ 5.15)
Note:
Please disable secure boot before install Linux driver.

Notice the kernel versions supported: 3,13 - 5.15. Unfortunately, you would have to install Kubuntu 24.04 or an older release and install the 5.15 kernel. Then apparently you'd be stuck there unless MSi updated their drivers.

Not sure how it works for 25.04, but do read the issues section, which may help.

Also remember LinUX is CaSe SenSitIve so downloads is not the same a s Downloads.
