Using chmod for /usr directory - ubuntu-10.10

I used the following command to change the permissions of the usr directory from root
root> chmod -R 777 /usr
Now when I try to use the sudo command it gives the following error:
sudo: must be setuid root
On googling, I found that this error happens if /usr is chowned and I need to reinstall Ubuntu. But am I getting this error for chmod? Is there anyway to fix this problem without reinstalling?

To setuid /usr/bin/sudo: chmod +s /usr/bin/sudo.
But you changed ALL file/directory attributes in /usr recursivly (-R). You really should try some rescue mode. I don't think you'll have any chance to repair it.

VS Code: NoPermissions (FileSystemError): Error: EACCES: permission denied

I'm trying to save a file called app.js on a folder called js.
Vs Code pop up this:
Failed to save 'app.js': Unable to write file 'vscode-remote://wsl+ubuntu-18.04/js/app.js'
(NoPermissions (FileSystemError): Error: EACCES: permission denied, mkdir '/js')
I tried:
sudo chown -R user /mnt/c/Users/myUser/Documents/myFolder/proyectFolder
but I still can't save this file.
Try this, fixed it for me
sudo chown -R username path
Example:
sudo chown -R emanuel /home/emanuel/test/
In the SSH terminal:
Recommended :
sudo chmod -R 777 folder_name_where_your_file_exists
or
sudo chmod -R 755 folder_name_where_your_file_exists
this works for me
sudo chown -R $USER:$USER /home/
TLDR;
If you're using a docker container, avoid making files from within the container because the owner and group permissions may cause problems with your editor (in my case VS Code)
I was running docker container for a Django project from Windows Terminal and using VS Code to edit my code.
It is a Linux file (since everything in Linux is a file) permission problem that arises because the files don't have proper user and/or group permissions. So VS Code tries to tell us that.
The problem I found only happened when I created files from within my docker container.
I would run docker exec ... bash
make new files using touch /path/to/file from the container bash
then try to edit those files on VS Code (say urls.py) only to get the scary permissions error preventing the file from saving.
I suspect that making files from within the container embellishes those files with different owner and group settings than your system would default to if you just ran the commands locally (not in the container).
Changing the file permissions with chown -hR and chgrp -hR would do the trick but to avoid the error altogether I stopped making files from within the container.
Try activating polling:
This worked for me during I tried using wsl.
The below is for individual file:
sudo chown yourUserNAme filename
For an entire directory it will be (when you write ls to terminal, you should see your directory to execute this command):
sudo chown yourUserNAme dirName
For recursive (i.e files and folders inside a folder):
sudo chown -R yourUserNAme dirName
Note: yourUserNAme is, if you do pwd under any Documents, you will see the path: /home/jhon/Documents. Here user is jhon.
Run VS Code as administrator and it will fix the problem.

Install the extension Save as Root in Remote SSH in VS code.
While saving press Ctrl + Shift + P.
This open the command palette.
Search Save as Root
It is a Linux user permissions problem.
you should use the command:
sudo chown -R $USER:$USER.

I am unable make file or directory in Visual Studio Code in Win Subsystem for Linux

I use this guide. When I take the step "Add a source code file", I am shown this report:
Unable to write file 'vscode-remote://wsl+ubuntu-20.04/home/alex/TEST/helloworld/helloworld' (NoPermissions (FileSystemError): Error: EACCES: permission denied, open '/home/alex/TEST/helloworld/helloworld')
I don't know what to do, can some one help me?
The VScode needs permissions thus
Try this command on your WSL terminal
sudo chown -R username /path/to/working/directory
Replace :
'username' with your username and the path of your directory
So I had the same problem and changing ownership via sudo chown -R username <path> did not work for me.
Simple solution!
My issue: Downloaded files for coursera project in zip. Copied files to ubuntu home/taylor/projects folder. and then tried accessing in vscode with code . I received the read error.
Solution:
go to your linux terminal.
Access the folder containing the files you are trying to work on.
For Example: app.py forms.py models.py in the projects folder. got to projects folder.
~/projects ls
app.py forms.py moodels.py routes.py
#they should be white meaning know permissions granted.
grant permissions
a. sudo chmod 777 app.py forms.py models.py routes.py
or
b. sudo chmod +rwx app.py forms.py models.py routes.py #r=read w=write x=execute
Try the above one by #uday Pratap, If not Working try this one's :
sudo chmod -R 777 folder_name_where_your_file_exists
or
sudo chmod -R 755 folder_name_where_your_file_exists

Unable to determine status of lock file in the data directory

I am trying to run multiple mongod instances on the same centos machine with different config files.
I am getting following error while running the instance as a service:
sudo service mongod1 start
/var/lib/mongo1: boost::filesystem::status: Permission denied: "/var/lib/mongo1/mongod.lock"
I have added the permissions for the /var/lib/mongo1 using:
sudo chmod -R 600 /var/lib/mongo1
I also tried with 700, 755 and 777 at the end but nothing seems to work.
mongod:mongod is the owner of the folder /var/lib/mongo1
Any help is appreciated.
I know this is really late but I was struggling with this for days and just now found the fix. That being said for future users running into this issue the solution if you're using SELinux is to check the context of the default mongodb path against your own to make sure they are the same by executing
ls -dZ /var/lib/mongo/
the output should look something like this
drwxr-xr-x. mongod mongod system_u:object_r:mongod_var_lib_t:s0 /var/lib/mongo/
if it's not then you can copy it by doing
chcon -R --reference=/var/lib/mongo /your/path
the source can be found here
Maybe the lock file is missing? Which might explain why chmod isn't having the desired effect...
Try:
touch /var/mongo1/mongod.lock
chown mongod:mongod
chmod 600 /var/mongo1/mongod.lock
important :
Don't try to restart mongo using sudo as it tries to change the user to root where as /var/lib/mongodb owner is mongod:mongod
Please remember that Directories needs to have execute permission, but the files within the directories do not need to execute permission.
The following 2 commands worked for me
$ sudo chmod -R 770 /var/lib/mongo1
$ sudo find /var/lib/mongo1 -type f -exec chmod 660 {} \;
This will first give everything under /var/lib/mongo1 execute permission, and then return all the normal files to having only read and write, but not execute.

MongoDB config error

Pretext: this has been asked before and i've tried implementing several solutions from previous posters. The only thing i can seem to get working is running mongo as sudo.
I'm not exactly sure what i'm doing wrong. I'm trying to do a tutorial using mongodb and every time i try to run the software i get back an error that its in a read-only directory. I'm on a mac running OS Sierra, i can force run it with sudo but i know thats wrong. I've been searching for an answer for awhile and i have already adjusted the folder permissions to 775 and nothing, then 777, still nothing.
Any help pointing me in the right direction would be greatly appreciated!
to resolve the "warning soft rlimits to low" check out this link - https://gist.github.com/tamitutor/6a1e41eec0ce021a9718
Lets start over as you are bouncing around on what you are trying.
Open activity monitor and kill any mongod process.
Go to your terminal and type which mongo - lets say it shows you download directory
cd to that directory and you should be in the bin directory
cd /mongo download directory/bin
sudo bash
mkdir -p /data/db
chmod 777 /data
chmod 777 /data/db
ls -ld /data/db this will validate you see the data/db directory as 777
exit
You're back in your mongo bin directory - if you are in /usr/local/bin skip this part.
If you are not in /usr/local/bin you will need to copy the mongo files to /usr/local/bin
sudo bash
ls - make sure you are in the correct directory
cp * /usr/local/bin
exit
which mongo should now show /usr/local/bin
type mongod to start it
open a new terminal and type mongo to connect to the instance
I recommend downloading Robo 3T (formally RoboMongo) to quickly check that you can connect.
If you do those steps, you should have no issues connecting to your local Mongo instance.
Your mongod.conf files should be in /usr/local/etc - check there to confirm you have your local host set.
Should be like net:
bindIp:127.0.0.1

Nominatim setup.sh permission denied

I followed this tutorial to install Nominatim. The installation procedure was not too complicated until the import process. I keep getting this same error over and over
CREATE FUNCTION
ERROR: could not access file "~/Nominatim/module/nominatim.so": Permission denied
ERROR: pgsql returned with error code (3)
pgsql returned with error code (3)
I tried doing as the tutorial proposed
chmod +x Nominatim
chmod +x Nominatim/module
Still didn't want to work. Got pissed and did chmod -R 777 Nominatim && chown -R user:usergroup. Nothing.
Finally, tried restarting and still nothing.
I am on ubuntu 14.04 using postgresql 9.3 postgis 2.1.
I feel dumb.
The tutorial wasn't clear enough on when to STOP for giving permissions.
In fact, I had to give my whole home folder the permission chmod +x user. They say that all parent require the execute permission but I wasn't about to give +x to my /usr folder.
Anyways. There. chmod +x /usr/user
