./make_bootable_linux: Permission denied

Hello:

 

I downloaded the latest Unraid *.zip to test it on my box and see how it does.

Unfortunately, after following the pertinent instructions, I have not been able to do so.

 

The 2Gb SD card was formatted as FAT32 using `gparted` and a new UUID was written to it to make sure it had a unique one, just in case.

 

[root@devuan UNRAID]# ./make_bootable_linux
-bash: ./make_bootable_linux: Permission denied
[root@devuan UNRAID]#

 

To make sure it was not a Linux glitch, I tried to run `make_bootable.bat` as Administrator on a netbook running XPSP3.

 

Same result: even though I am logged into XP as Administrator, the system tells me that I can only run the bat file as Administrator.

 

I'd appreciate some insight into this problem as I am keen to try Unraid.

 

Best,

 

JHM

The 2Gb SD card

You must use a USB memory stick, SD cards aren't supported.

Ahh ...

Had not seen that, must have missed it.

Where is that?

No matter.

If that doesn't work, try copying the make bootable script to your home folder and make sure the executable bit is set, then try executing it from there.

 

Also, if your test rig supports UEFI booting, you could rename the EFI- folder to just EFI and see if it will boot using UEFI instead of bios.

Did you try sudo ./make_bootable_linux

 

No.

I am running the script as root:

[root@devuan UNRAID]# whoami
root
[root@devuan UNRAID]# ./make_bootable_linux
-bash: ./make_bootable_linux: Permission denied
[root@devuan UNRAID]#

OK

Just in case, running it as root from the /home folder has the same result:

I fail to understand why root lacks permissions to run the script from the flash drive.

Still, something seems to be amiss.

Wording might be improved ?

 

Could be.

In these days when you can run a full fledged distribution with persistence/portability from an SD card, the difference may not be immediately obvious or slip by, like with me.

 

If I may suggest:

You will also need a quality USB flash device that is 1GB or larger.

Note that SD cards are not supported. For full hardware requirements, visit our product page.

FAT32 doesn't support linux permissions.

 

Ahh ...

Forgotten tidbit.

Thanks for the reminder.

 

But running the script from the USB drive from an XPSP3 instalation while logged in as Administrator also gives me a similar error:

 

Make Bootable v1.5
ERROR - script must be run as administrator.

Right click and select 'Run as administrator'
or execute from an elevated command prompt.

Press any key to continue ...

 

As expected, it goes the same way if I open a terminal and execute 'make_bootable'.

 

Please advise.

 

Thanks in advance,

Hello:

> What about the USB creator tool?

>

My box runs Linux.

I don't have Mac hardware.

The XPSP3 installation I used as an alternative (to test what was happening) happened to be at hand.

Is not mine.

And Unraid runs on Linux.

 

No idea what the problem is?

Thanks in advance,

Here are the steps I followed that worked.

Format drive fat32, label UNRAID

Extract archive to mounted drive

copy make_bootable_linux to hard drive

unmount (not eject) USB drive

sudo bash ./make_bootable_linux

In case anyone else encounters this issue I’ve updated the relevant part of the “Getting Started” section of the online documentation (accessible via the manual link at the bottom of the unRaid GUI) with these steps so hopefully in the future other Linux users will also be successful :)

The make bootable script could probably be rewritten to solve this, and I'm sure it works as is on some distro's. For now though, it's a perfectly acceptable work around, and I didn't feel like spending the time to troubleshoot the script properly.

 

I think, but not sure, that the issue involves the way some distro's automatically mount inserted media, and unmounting manually before running the script solves that.

Just to add to the discussion:

 

I was tinkering with this yesterday as well, and ran into issues. After finding this thread, I tried the sequence of steps that jonathanm posted above and itimpi added to the wiki, and those worked fine. 2 notes:

  1. I found that if I forget to unmount the USB, then just running the script a 2nd time also did the trick. Seems like the 1st attempt unmounts the drive but then fails, and the 2nd attempt succeeds on the unmounted drive.
  2. I got the same results whether running the script as "sudo bash ./make_bootable_linux" or leaving bash out and running "sudo ./make_bootable_linux". That may not be the case for other distros, not sure.

But before I found this thread, I stumbled upon a different solution: editing the script slightly. For me the key was in the error that I repeatedly got when running the script:

sudo: /tmp/UNRAID/syslinux/make_bootable_linux.sh: command not found

 

JHM got this error at least once, and there are other posts that mention this error.

 

The error seems to be indicating that the script is failing because sudo sees the path /tmp/UNRAID/syslinux/make_bootable_linux.sh without a command, and doesn't know what to do with it. Or at least I think that is what is happening.

 

To fix it, I found the line below, towards then end of the script:

sudo /tmp/UNRAID/syslinux/make_bootable_linux.sh $TARGET

 

and added bash before sudo, to make it look like this:

sudo bash /tmp/UNRAID/syslinux/make_bootable_linux.sh $TARGET

 

The edited script will now complete without unmounting the USB. When running from the PC either "sudo bash ./make_bootable_linux" or "sudo ./make_bootable_linux" can be used. The script will also now run when launched from the USB itself, but only when using "sudo bash ./make_bootable_linux".

 

Of course, inserting bash into that line in the script assumes that the shell being used is bash, but that is a pretty fair assumption these days. Maybe there is a way to call the shell in the script without specifying bash, but I don't know how to do that.

 

Anywho, hope that helps.
