Going back to the OP for a second:

I forgot to check: how *exactly* did you transfer the ISO image to the installation medium?

The "mounting problem" is usually caused by incorrect transfer — were you using an obsolete tool such as unetbootin?

Rufus also has trouble with Debian images, if the posts on these boards are anything to go by.

Alright, so there's a pretty long list of stuff in the log terminal. I'm not sure what's relevant and what isn't but it's on a different machine than the one I'm using to post this so I'm not sure how to go about getting it all into this post without simply typing it all out. Is there some way to screenshot this terminal or export it to a file? if I export it to a file, where would this file be stored, since the OS isn't even installed?

If all else fails, I can just take a picture of the screen (gotta love smartphones) and attach it, I guess.

As for how I transferred the ISO to the USB stick, I used the USB Image Writer in Linux Mint 18.3 MATE. Which is on the machine I'm currently using to post this.

Sometimes the useful information in the log is obvious. Sometimes it is not...
The full installation log file is in /var/log/ (syslog or something). Until the successful end of the installation is remains in volatile memory and is lost on shutdown.
You can switch to an ash shell in console tty2 or tty3 and copy it on a manually mounted USB drive.

I'm not exceptionally familiar with the linux terminal so maybe I'm doing this wrong, but it doesn't look like I have permission to copy the log file.

I put in a small, empty USB stick which became sde, according to fdisk -l. I mounted /dev/sde/ to /mnt/ like so:
Code: Select all
mount /dev/sde/ /mnt/

It made no response. I assumed it was mounted. I then tried to copy the entire directory of /var/log/ to the USB, as follows:
Code: Select all
cp /var/log/ /mnt/
to which it responds with:
Code: Select all
cp: omitting directoy '/var/log/'

At this point, I attempted to navigate to both /mnt/ and /dev/sde/ but was denied permission.

I'll just post the pic I took of the screen later.

You can check the mounted filesystems with mount or df.

Copying a directory requires -r (recursive). Otherwise, use
Code: Select all
cp /var/log/* /mnt

/dev/sde is a device file, not a directory. You cannot browse it. As root, you should have permission to browse any directory, but /mnt may be empty as your cp command did not copy anything.

PS : I cannot see your picture for now.

Ugh. Photobucket has become next to useless.

I will try copying the log file again when I get a chance.

EDIT: I decided I'd try it right now. I got the log file to copy. It's pretty long, but here are the last few lines of syslog:
Code: Select all
Mar 14 00:36:31 kernel: [  204.024629] Btrfs loaded, crc32c=crc32c-generic

Mar 14 00:37:42 init: starting pid 437, tty '/dev/tty3': '-/bin/sh'

Does that tell you anything useful? I don't know what this journal is that it seems to be having trouble with but it must have something to do with the file system it can't mount.

The only error messages in this quote are related to sdd1. But your previous quote mentionned sdb. Is it the same device with a different name ?

About the error message itself, it seems that it might indicate the SD card capacity is fake.
Could you check it with F3 aka Fight Flash Fraud or Fight Fake Flash ?

I must be missing somelthing. I installed F3 from the Software Manager in Mint but I can't find it anywhere to open it and test the SD card. Even when I search for it in the applicatons: nothing. Yet the software manager says it's installed.

F3 is a set of command-line tools, so I guess you must run them in a terminal shell. I have only heard about it and never used it.
According to the man pages :
- f3write and f3read run on a mounted filesystem (spreading on the whole device) so you would have to create a filesystem which can be mounted (you can try ext2, ext4 without a journal, FAT).
- f3probe runs on the block device but is flagged experimental (note: might destroy data on the device).

Ah. Terminal commands. That explains it. Alright, I will format the SD card to something mountable and give it a scan when I get home from work today.

I've had this card for years though, I'm pretty sure it's good. We'll see.

Also: Yes. Same device with a different name. Every time I tried to get the error log I had to go through the installation again. Had different USBs plugged in for copying, etc,

Another cause might be that the SD card reader cannot access the whole card capacity.

I think you should try again and follow the documentation this time:

https://www.debian.org/releases/stretch ... -isohybrid

That GUI tool looks a lot like unetbootin and we know that *does not* work with Debian ISO images.

Please, don't come back on this again. It is just a waste of time. A bad copy of the image does not cause this kind of problem.

Yeah, I know it's not a bad installation media. I've burned plenty of Linux ISOs (Mint, Debian, Puppy, etc) with Mint USB Image Writer and they've all worked just fine.

Anyway....

So it turns out the problem was the SD card after all. I couldn't get F3 to work. I'm not sure if I was doing it wrong or something but when I looked up the documentation and tried
Code: Select all
./f3probe --destructive --time-ops /dev/sdc
on my Mint machine, it said there was no such file or directory. Whatever. I decided to put another SD card I have, a 16GB one, in the USB adapter and try installing Debian on that instead. And it worked. So Debian is now installing on my 16GB SD card.

Thank you, p.H. You've been an excellent help. I would never have figured any of this out without you, mate.

EDIT: Turns out I still can't put the SD card right into the internal miniPCI-E card reader and install Debian though. It runs so slow in the USB adapter I don't know if it will let me edit the fstab file. I gave it a few minutes and it still wouldn't load more than the wallpaper and mouse cursor. *sigh*.
