LinuxQuestions.org - read only error

- - read only error (https://www.linuxquestions.org/questions/linux-newbie-8/read-only-error-4175607878/)

hey, i'm new to Linux, obviously.
I have fedora running on a bootable usb
I can not run firefox, it says the firefox profile cannot be loaded, it may be missing or inaccessible
secondly, when I try to run a 'sudo yum update' it redirects to '/usr/bin/dnf update' (which I presume is fine) but then says config error: Read-only fyle system: '/var/log/dnf.log'
I have read threads saying the read only error only comes about when massive damage has been done to the system, and granted i'm a brand-spankin new user, I don't think I've done anything to massively damage the system, I've literally just changed directories and been working on navigation.

side question, what is the stock text editor for fedora?

1. RHEL/Centos still use yum (at least up to v6), but Fedora (bleeding edge precursor to RHEL releases) has moved on to dnf - so no worries there

2. you can check rw access of your mounts thus

Code:

sudo mount

3. default editor should be vim (sometimes symlinked to 'vi') afaik.

HTH & Welcome to LQ :)

What sort of USB - thumb drive, or external (real) hard drive ?. How did you create this system - post a link is fine.
From a terminal post (all) the output from this

Code:

df -hT

cat /etc/fstab

lsblk -f

As in most things Linux, there are innumerable editors available. Which GUI editor ships depends on desktop. Which iso did you install ?.

hello chris thank you, after mounting it i'm encountering the same error =/
wait, I think i'm misunderstanding, I apologize I probably need rest really lol
the data the mount command returned did not have any errors listed, but I will keep studying to at least be able to understand the data it is returning to be able to further identify the error. thank you again

Please post the output of

Code:

sudo mount

and the cmds asked for by syg00 (also prefixed with sudo if reqd).
Please use CODE tags https://www.linuxquestions.org/quest...do=bbcode#code when doing so - thank you

sandisk 16gb thumb drive, https://getfedora.org/en/workstation/download/
also, to be completely honest with you I cant say I've installed an iso yet. today is my first day in Linux so please forgive the incompetence

Don't worry about not knowing (yet) - we're all here to learn.

What you downloaded was an iso - how did you "install" it on the thumb-drive ?. Details needed.
Also, to run those commands I gave you, hit the "Windows" key if you have one, and type "terminal". It will give you a seesion like an old DOS prompt. Enter the commands, and ue the "Edit" menu item to copy them (highlight with the mouse first). Paste here.
That is probably gnome desktop, so your editor will be gedit. Amongst others as per above.

sorry for the delay, the usb cant connect to the internet currently so I typed that over to copy it, will be copying the results of the other inquiry shortly

I used rufus, and i'm unable to copy at the moment, the laptop running the thumbdrive wont run firefox so I copied over what chris requested by typing, about to do the same for your command output requests as well, pausing for a little nicotine first though, will start in 2 min

That's probably enough - so you are running as a liveCD rather than a full install. Let me go test.

I couldn't get the arrows to copy exactly, but did what I could. also, code wrapping not wanting to work

Real life intervened - rain stopped, dog needed a walk ... :p

Dunno what your issue is - I fired up a F25 Live desktop iso I had laying around. No problems.
That "/dev/mapper/live-rw on / type ext4 (ro,relatime,seclabel,data=ordered)" should be rw. Maybe some error messages, but hard to know what to look for. Try this in a terminal, and post the output.

Code:

journalctl -b 0 | grep -A10 -Ei "(sysroot|switching root)"

Did you check the iso you downloaded to ensure it was valid ?. I've not used rufus, so can't comment on its veracity.

If you simply wrote the iso file to a flash drive it would still be an iso file system, which is read only. If you installed the os to a flash drive, then it should be read/write.
