I think that tells everything.
Is that 222a22ee-7f5b-46b1-a668-5d80ef7c92a8 mounted? Where is it mounted?
You can check it with
mount | grep sda4

kamranhere · November 9, 2021, 6:57am

it gives

mount | grep sda4
/dev/sda4 on /mnt/K type ext4 (rw,nosuid,nodev,relatime,x-gvfs-show)

kovacslt · November 9, 2021, 7:00am

You see it:
/mnt/K
versus
/media/kamran/222a22ee-7f5b-46b1-a668-5d80ef7c92a8

kamranhere · November 9, 2021, 7:08am

thanks kova
but i am new in this os
installed yesterday

just googling and copying pasting in terminal

so can you please tell me thee whole command to change permission so that i can copy files and create folder that would be very kind of you

kamranhere · November 9, 2021, 7:27am

@kovacslt are you there?

kovacslt · November 9, 2021, 7:27am

OK, try this:
sudo chgrp adm /mnt/K
I assume, you know why exactly you want to change group ownership to ‘adm’, probably user ‘kamran’ belongs to that group…
Let me know if something still doesn’t work.

kamranhere · November 9, 2021, 7:40am

after this still i cant create of copy files

kovacslt · November 9, 2021, 7:52am

I don’t see here any attempt to copy files there.
But to be sure about it, please do this:
cd /mnt
ls -l
and paste here the output of ls -l.
After that let’s see what groups you are in:
groups
paste here the output…
I think it would be good to know, what exatcly is on that partition? I mean, is there another system installed, or you keep there only data files, such as documents, music, movies, etc.?

kamranhere · November 9, 2021, 7:57am

this OS is just much more COMPLICATED than I thought.
please help me @kovacslt
i am going to get panic attack
just stuck in this issue since morning

kamranhere · November 9, 2021, 7:58am

this might help u little bit

kovacslt · November 9, 2021, 8:06am

Don’t panic!

kamranhere · November 9, 2021, 8:09am

this was epic lol

but i need solution sir

kamranhere · November 9, 2021, 8:10am

now i changed thee mount location to default

lol
but i think this won’t help

kovacslt · November 9, 2021, 8:16am

The very quick solution was to give yourself the ownership:
cd /mnt
sudo chown kamran:kamran K -R
After that everything will be owned by user ‘kamran’, thus you’ll be able to write, delete, create, etc…
I’d do this only, if there are only data files I’d need to be able to modify.
So question again: what do you store there?

Akito · November 9, 2021, 9:10am

Sounds like a LInuxer’s every day morning.

kovacslt · November 9, 2021, 9:28am

He (or she, I don’t know) reached some post limit, so we countinued in private.
I could bet we solved the problem, but now the same partition seems to be on another different mount point (namely /media/kamran/K ), probably Gnome Disks likes to mount there?
Anyway, the partition seemed to be empty, so I told him to chown it simply.
cd /media/kamran
chown kamran:kamran K
upd: Yes, this solved his/her problem for now.
