I try to change default context in kubernetes but I get config.lock: permission denied error.
$ kubectl config set-context $(kubectl config current-context) --namespace=custom_namespace
error: open /home/vagrant/.kube/config.lock: permission denied
Make sure that kubernetes config directory has the same permissions as kubernetes config file.
Solution Beside, steps specified in kubernetes documentation.
$ mkdir -p $HOME/.kube
$ sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config
$ sudo chown $(id -u):$(id -g) $HOME/.kube/config
Add change permissions on $HOME/.kube/ directory.
$ sudo chown -R $(id -u):$(id -g) $HOME/.kube/
For me it helped as described here:
https://github.com/kubernetes/kubectl/issues/493
A reason this could happen is if the actual KUBECONFIG environmental variable is set to an incorrect location or file. You can solve that by simply setting it to nothing/empty like this on power shell:
$env:KUBECONFIG=""
and verify it like this:
$env:KUBECONFIG
Alternatively, solve it by setting the KUBECONFIG environmental variable like:
$env:KUBECONFIG="C:\Users\your_user_name\.kube\config"
if you are on windows system. try to run command as administrator.
this fix error.
open .lock: access is denied.

I have installed pg-pool 2 using their GitHub repository
When I use the command:
pgpool -n &
I am getting the following error:
For this you have to create a folder pgpool in the /var/run directory
cd /var/run
sudo mkdir pgpool
and then give write rights to the directory:

I'm trying to run the flutter commands but it gives me this error
Flutter failed to write to a file at
"/usr/local/Caskroom/flutter/3.0.3/flutter/bin/cache/flutter_version_check.sta
mp".
Please ensure that the SDK and/or project is installed in a location that has
read/write permissions for the current user.
Try running:
sudo chown -R $(whoami)
/usr/local/Caskroom/flutter/3.0.3/flutter/bin/cache/flutter_version_check.st
amp
please help how to fix this issue.
You have to give permission to your username to access that folder
sudo chown -R <your_username> /flutter_sdk_path/
Check permission for the mentioned directory via:
ls -l /usr/local/Caskroom/flutter
Then run this command:
sudo chown -R [user]:root /opt/flutter
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.

It is a Linux user permissions problem.
you should use the command:
sudo chown -R $USER:$USER.
I believe I ended up mixing up permissions at /etc/ssl directories tree as the last modification was made on 18th November and a day after I could not get my PostgreSQL to work.
When I type in
sudo service postgresql start
I get
FATAL: could not access private key file “/etc/ssl/private/ssl-cert-snakeoil.key”: Permission denied
Checking permissions
~$ sudo -i
~$ ls -la /etc/ssl/private
drw-r----- 2 root ssl-cert 4096 Nov 18 21:10 .
-rwxrwxrwx 1 postgres postgres 1704 Set 4 11:26 ssl-cert-snakeoil.key
Checking group composition
~$ id postgres
uid=114(postgres) gid=127(postgres) groups=127(postgres),114(ssl-cert)
Also I noticed that my ssl-cert-snakeoil.pem file at /etc/ssl/certs/ doesn't have a symlink. I don't know if this makes any difference...
Please, help me sort this out.
Thanks.
Edit: Should it be posted on serverfault instead?
Try adding postgres user to the group ssl-cert
Run the below code to fix your issue:
# > It happened to me and it turned out that I removed erroneously the postgres user from "ssl-cert" group, set it back with
sudo gpasswd -a postgres ssl-cert
# Fixed ownership and mode
sudo chown root:ssl-cert /etc/ssl/private/ssl-cert-snakeoil.key
sudo chmod 740 /etc/ssl/private/ssl-cert-snakeoil.key
# now postgresql starts! (and install command doesn't fail anymore)
sudo /etc/init.d/postgresql start
courtsey to GabLeRoux
Check the output of
$ sudo -u postgres
$ cd /etc/ssl/private
$ ls
If the response is "Permission denied" do
$ chown postgres:ssl-cert /etc/ssl/private/
$ chown postgres:postgres /etc/ssl/private/ssl-cert-snakeoil.key
Only thing that will work if you have changed permissions for /etc/ssl/private
mkdir /etc/ssl/private-copy; mv /etc/ssl/private/* /etc/ssl/private-copy/; rm -r /etc/ssl/private; mv /etc/ssl/private-copy /etc/ssl/private; chmod -R 0700 /etc/ssl/private; chown -R postgres /etc/ssl/private
Copy this whole command (It's a one line code).
If this doesn't work for you, ckeck your postgres user groups by groups postgres and make sure your postgres user have ssl-cert root postgres (Order doesn't matter).
Now lets check your file permissions on ssl/private :
$ ls -la /etc/ssl/
> drwx------ 2 postgres root private
If this is not the output change your permissions with sudo chmod -R 700 /etc/ssl/private and for owners chown -R postgres:root /etc/ssl/private
//Now check permissions on ssl-cert-snakeoil.key,
//which will be inside your **private** directory.
$ ls -la /etc/ssl/private/ssl-cert-snakeoil.key
> -rwx------ 1 postgres root /etc/ssl/private/ssl-cert-snakeoil.key
I was suffering from this issue when attempting to start Postgresql on a remote docker instance. I eventually tracked down the crazy solution here. Basically you have to recreate the directories, chown on it's own doesn't work:
mkdir /etc/ssl/private-copy; mv /etc/ssl/private/* /etc/ssl/private-copy/; rm -r /etc/ssl/private; mv /etc/ssl/private-copy /etc/ssl/private; chmod -R 0700 /etc/ssl/private; chown -R postgres /etc/ssl/private
This error was preventing my PostgreSQL server from running locally.
The following worked for me:
sudo chown postgres:postgres /etc/ssl/private/ssl-cert-snakeoil.key
sudo chmod 600 /etc/ssl/private/ssl-cert-snakeoil.key
Also make sure that /etc/ssl/private has enough permissions.
Some programs can be incredibly pedantic and cost you valuable hours. By running journalctl after sudo systemctl start postgresql I'd see various errors like:
FATAL: could not load private key file "/etc/ssl/private/ssl-cert-snakeoil.key": Permission denied
FATAL: private key file "/etc/ssl/private/ssl-cert-snakeoil.key" must be owned by the database user or root
FATAL: private key file "/etc/ssl/private/ssl-cert-snakeoil.key" has group or world access
DETAIL: File must have permissions u=rw (0600) or less if owned by the database user, or permissions u=rw,g=r (0640) or less if owned by root.
I couldn't make it with work sudo chmod root:root, so I had to settle for sudo chmod postgres:postgres.
EDIT
I haven't tried it, but running deleting and regenerating the snakeoil certificate might work as well:
make-ssl-cert generate-default-snakeoil --force-overwrite
(You may have to run it with sudo, don't know.)
Try setting permissions on the .key file to 600. Postgres doesn't like key files with group or world permissions set. You may also need to change the owner to postgres, though I'm not sure about that.
I am running the postgres server in WSL, and I was facing the error with the ssl-cert file. I managed to make it work by changing the owner of the file to the postgres user I had created, adding the expected user and group IDs to the user as required of the application (111 and 116, respectively, as gleaned from helpful error messages), and voila, I have an active server from within WSL.
sudo useradd postgres
sudo usermod -u 111 -g 116 -a -G ssl-cert postgres
sudo chown postgres /etc/ssl/private/ssl-cert-snakeoil.key
After running the above, there were two more files the user running the server (postgres for me) needed permission to access, both residing in /var/postgresql. I used sudo chown -- twice more to give ownership to postgres. Running sudo service postgresql start will tell you which files you'll need to transfer ownership of through any error messages.
I had other certificates under /etc/ssl/private and hence, changing permissions recursively was out of question.
I tried adding postgres user to ssl-cert group that didn't help either.
I modified the permission of /etc/ssl/private to 716, basically saying that anyone else other than root (user) and ssl-cert (group) can read and execute the directory.
sudo chmod 716 /etc/ssl/private
Then, I modified the ownership of ssl-cert-snakeoil.key
sudo chown postgres:postgres /etc/ssl/private/ssl-cert-snakeoil.key
This worked for me, basically a combination of the answers by #devops and #Noushad
In my .bashrc I have
function bindfs () {
mkdir -p ~/$1
sudo /usr/bin/bindfs -u $(id -u) -g $(id -g) $1 ~/$1
}
in order to be able, as a normal user, to read, write, execute files on ext3 file systems auto-mounted below /media/. This works fine.
However, I would like to know the inverse operation of bindfs. Otherwise I cannot umount the USB storage media before unplugging.
you can use umount
sudo umount ~/$1
bindfs is FUSE filesystem and can be used from non-privileged users is
user_allow_other
is set in /etc/fuse.conf.
It's natural counter-part is
fusermount -u
that can be run by standard users, as well
