Chainloading failure: Toshiba Tecra C40-C UEFI & Samsung SSD MZNLF128HCHP-000

[Tom Elliott]

@Tom-Elliott it appears, maybe, /home/fog folder doesn’t exist?

[mabarton]

@Tom-Elliott
It doesn’t

@mabarton said in Chainloading failure: Toshiba Tecra C40-C UEFI & Samsung SSD MZNLF128HCHP-000:

@Tom-Elliott
It doesn’t

Then make it.
mkdir /home/fog
chown fog:fog /home/fog

@Wayne-Workman I guess I have to ask a silly question, why is it trying to use the /home/fog directory for image capture? That’s a bit unusual.

[Tom Elliott]

@mabarton there is the upload error. Run:sudo mkdir -p /home/fog; sudo chown -R fog:fog /home/fog

[mabarton]

@Wayne-Workman

Doing it

[george1421]

@Tom-Elliott that would be sudo mkdir… unless there is a new command.

[Tom Elliott]

@george1421 it’s not, but fog user is Linux side and ftp is logging in just fine. Linux can’t find users home due and returns false.

[Wayne Workman]

Lol I’m out - gunned here. I’m on mobile.

@george1421 it’s the fog users ftp root directory. As soon as you authenticate via ftp as fog, you plop into the users home directory.

@Tom-Elliott
I made the directory and use the chown command

I just don’t understand the fog:fog part. It may not be necessary for me to understand to make it work but I want to understand it.

[Wayne Workman]

@mabarton then you should be good now.

[Tom Elliott]

@mabarton now you should be able to upload. Booting is separate but imaging should be able to happen.

[mabarton]

@Tom-Elliott
When I made this server I had never used any computer other than a Windows machine, so I did not know about the directories, commands…I knew zilch.

[Tom Elliott]

@mabarton the chown changes the owner to allow the fog user to access it.

[mabarton]

@Tom-Elliott

The school was doing computers one at a time before.

I really appreciate this and so will our school! Should this fix the chainloading error as well?

[Tom Elliott]

@mabarton fog:fog is user:group

[Wayne Workman]

@mabarton this is linux permissions 101. A incredibly brief explanation wrote by someone on a cell phone:

First part is owner, second part is group. Third which isn’t included is everyone.

Every linux user also has their own group by default and Linux does not allow deleting a user’s group.

Basically - setting the ownership tells linux that this user and this users group (which only has that one user in it) own that directory.

[Tom Elliott]

@mabarton no. The chain load issue is as George was discussing. Uefi exit is not pretty, but on imaging you should ensure secure boot is off for download, though I would recommend for both upload and download.

[mabarton]

@Tom-Elliott
That was where I was lost. We use chown often with students.

[Tom Elliott]

@mabarton for the chain load, if you set host efi exit to type exit and reupload with secure boot off, then deploy to system with secure boot off, I suspect you might have much more luck.
