[SOLVED] proc permission is denied.

M. Yusuf Suleman · 09-01-2021, 04:55 AM

When I run Visual Studio Code. It gives the error:

Code:

grep: /proc/version: Permission denied

.
Somewhere on the internet I found that entering [CODE]cat proc/version[/CODE will fix it but still says permission is denied. I can't use

Code:

chmod

to change permission, It also says a proc error when starting Fedora.

that is interesting. What OS is it exactly?

Code:

user@host:/tmp$ ls -l /proc/version
-r--r--r-- 1 root root 0 sept  1 12:08 /proc/version
user@host:/tmp$ cat /proc/version
Linux version 5.4.0-81-generic ...

Fedora 33 running in Termux (App) in Android 11.

That is not a real linux environment, but an emulator. Probably that's why it is different.

I can run that command with no errors as a regular user, but you mention "Visual Studio Code" is somehow involved...what, exactly are you doing?? What is this code? Can you just go to a regular terminal in Fedora and run that command??

I was using a normal Fedora Terminal, I meant by the last reply; that I am running it on my phone and I am able to access it through my laptop.

It's not very clear on what you're running where.

I doubt you're running Fedora "in" Termux, you are probably only using the SSH client?

Are you running Fedora on a phone (what hardware?) or are you running Fedora on a laptop which you are connecting to through a phone?

What is the output of the following commands:

Code:

ls -l /proc/version
cat /proc/version
sudo cat /proc/version
ls -l /etc/*release*
cat /etc/*release*
sudo cat /etc/*release*
inxi -S

Please be clear on what/where you are entering them into (e.g. phone or laptop, Termux terminal or Fedora terminal, etc).

Both Fedora and Termux Fail with the same error.

Did you actually read any part of the post you quoted?

If you want people to help, you need to answer questions and follow instructions.

You're still not answering the questions asked. Again, what "Visual Studio Code" are you running where and how?? Because again, typing in the cat command as you posted it works fine for any non-root user.

GentleThotSeaMonkey · 09-01-2021, 06:51 PM

Try rebooting, and then cat /proc/version before you do anything else.

Are you familiar with the 'permission modes' for files, as displayed by ls -l?

Yes, do the commands in #7. (root can chmod 0 and then only sudo=root can read it)

Also, does "starting" mean booting or (ssh) login, to you, when you say: "It also says a proc error when starting Fedora."? ?? (a login script may try to read it)

And you might need sudo to use chmod. Do you understand sudo=root concepts?

For learning, you can web-research the basic concepts of /proc (or anything).

I can't make a non root user and I am running the latest version of VS Code.

Rebooting does not work on that command ls does not work. I am root. I fo a normal boot instead of SSH.

There are a lot of confusions here. I guess we are speaking about two hosts:
1. a [smart]phone with android 11 and termux. This is not a real linux and that's why you have those problems with /proc/version, sudo, reboot and similar commands.
2. your PC running fedora(?) and Visual Studio Code.
But it is only my guess, I have no idea about the real setup. Would be nice to explain.

I am using my phone because my laptop had proprietary drivers. So I use a VNC viewer to access it.

Sorry, you are *STILL* not making any sense and not understanding what you're being asked. You STILL don't say what "VS Code" has to do with any of this, or how. And if you're the root user, you absolutely CAN make any other users you want. Root can do anything on a *nix system.

Again, you're not making sense. No idea how 'proprietary drivers' fit into things here, and you don't say what kind of laptop, but as pan64 mentioned, if you're doing this on Android, that is *NOT* Fedora (or Linux), which is why things don't work.

Your laptop can most likely run Linux just fine.
