[SOLVED] Giving permission to write data on home partition

aaron4atkinson · 2020-07-21 19:22:49

Hello, this is my first post as I am very new to Arch-Linux. I have installed KDE as my desktop environment in my root partition, my issue is that I cannot paste files into my home partition and whenever I click in to read the files in my home partition I have too enter my root password. Any help would be appreciated and if you would like more info then simply ask.

You're not supposed to have write access to the /home partition as regular user - only your $HOME.
What's the output of "ls -la /home"?

aaron4atkinson · 2020-07-21 19:33:40

The output is
total 12
drwxr-xr-x 3 root root 4096 Jul 20 01:19 .
drwxr-xr-x 17 root root 4096 Jul 19 20:35 ..
drwx------ 11 aaronn aaronn 4096 Jul 21 10:57 aaronn

So, you shoud™ have writing access to /home/aaronn (which should be the output of "echo $HOME") but not /home - which is expected.
Why do you want to write into /home?

aaron4atkinson · 2020-07-21 19:37:27

I thought I was supposed to store most of my things there. At current I cannot save new programs and information to my home folder from the desktop, only my root partition which is just 50Gbs in size

seth · 2020-07-21 19:42:28

Where does that "home folder" point (ie. which path does it resolve)?

aaron4atkinson · 2020-07-21 19:46:12

When I set up the home folder I put it under /mnt then mounted sda3 (my home partition) to it when I installed arch-linux

seth · 2020-07-21 19:50:10

WHAT?

What's the output of

lsblk -f
cat /etc/fstab
echo $HOME
grep aaronn /etc/passwd # this does not reveal a password

aaron4atkinson · 2020-07-21 20:06:22

lsblk:

echo $HOME:
/home/aaronn

grep aaronn /etc/passwd:
aaronn:x:1000:1000::/home/aaronn:/bin/bash

Did I setup the partitions incorrectly? To clarify I mounted sda3 to a file at /mnt/home

seth · 2020-07-21 20:08:51

You want to mount it to "/home"
Which tutorial did you follow to install archlinux?

aaron4atkinson · 2020-07-21 20:14:19

I just followed the archlinux tutorial on the wiki

seth · 2020-07-21 20:20:12

You were supposed to mount it to /mnt before arch-chroot'ing and "https://wiki.archlinux.org/index.php/In … uide#Fstab" would have gotten you a different /etc/fstab…

Anyway, mount sda3 to /home. You should be good.

Notice!
You may want to "sudo cp -a /home/aaronn /mnt" first (so it will exist in the new /home path) and if everything works, delete it from the UNMOUNTED /home (so you won't get warnings about /home not being empty when mounting sda3 there)

aaron4atkinson · 2020-07-21 20:35:41

When I run the command "sudo cp -a /home/aaronn/mnt" it gives me this response
cp: missing destination file operand after '/home/aaronn/mnt'
Try 'cp --help' for more information.

shouldn't I just use mkdir to make a new file? Also when I reboot the computer in unmounts sda3 from home, how should I fix that

seth · 2020-07-21 20:39:15

Sorry, botched the space key…
"sudo cp -a /home /aaronn /mnt"

how should I fix that

By adding an entry to /etc/fstab…

Are you sure you followed the installation guide?
I'd review it and check which steps you might have missed/skipped/ignored…

rowdog · 2020-07-21 21:53:08

I believe Seth actually meant

sudo cp -a /home/aaronn /mnt

aaron4atkinson · 2020-07-21 22:06:21

I went back in through my arch setup hardrive and generated the fstab file after running the command you said I should. It said that the file directory "aaronn" did not exist. I also mounted the aprtitions as it says in the install guide before generating the fstab file. My issue is that no matter what I do the fstab file doesn't seem to "stick" and whenever I reboot my computer and run nano too view the file it gives me an error saying it does not exist.

Should I just manually make an fstab file and put in all of the info?

loqs · 2020-07-21 22:27:42

After you performed Installation_guide#Mount_the_file_systems what is the output of

findmnt /mnt

aaron4atkinson · 2020-07-21 22:34:03

After running findmnt /mnt I got the result
TARGET SOURCE FSTYPE OPTIONS
/mnt /dev/sda2 ext4 rw,relatime

loqs · 2020-07-21 22:44:24

Which explains why genfstab is not creating an entry for /home as there is nothing mounted at /mnt/home.

aaron4atkinson · 2020-07-21 23:01:58

Alright, I mounted sda2 @ /mnt and sda3 @ /mnt/home
I used findmnt at both /mnt and /mnt/home and the partitions are in the right place. I used the command "genfstab -U /mnt >> /mnt/etc/fstab". I've realized that the fstab files are simply not coming up because I was trying to view them outside of startup. Both sda2 and sda3 are there and under type sda3 is recorded as /home.

Is there anything else I should do?

loqs · 2020-07-21 23:06:14

Check that /mnt//home/aaronn exists, inside the chroot would be /home/aaronn. If the cp command succeeded in copying the home directory it should exist.

The file exists, Plasma is failing to load the desktop after login. I'm guessing the best way to solve that issue would be to redownload the desktop and remake the users. Am I correct in doing this?

loqs · 2020-07-21 23:58:56

If the issue is caused by files in the user's home directory not belonging to that user that can be fixed without having to recreate the user.
