'Permission denied' trying mkdir in 'Documents' folder using Linux on Windows 10 - linux

I'm running Windows 10 and have tried creating a folder under 'Documents' folder using Cygwin, Git Bash, and Ubuntu subsystem for Windows 10 to no avail.
mkdir testfolder
Have also tried
sudo mkdir testfolder
and I get the resulting message mkdir: cannot create directory 'testfolder': Permission denied
I've tried running as administrator, I've tried doing chmod 777 Documents, I am root when using Ubuntu, but nothing seems to solve this error message.
One other note, I have no problem creating a directory in other folders at the same level such as 'Downloads' or 'Desktop'.
Any help would be greatly appreciated. Thanks!

Linux - Permissions to Create Directory / Delete Directory and Files / Change Permission for an entire Drive

I need your help, in order to allow me, to create directories, delete files, save files in directories. Right now, I'm unable to do anything in this Drive "Ubuntu-Dados".
I've already tried a bunch varieties of commands, from this site, and including running Nautilus, "sudo chmod -R -v 777 *", and nothing is working. Below is the result of my attempt to this issue. I need access to do anything in this Drive. - I'm using Ubuntu 20.04

Azure Ubuntu VM - Execute Custom Script (Permission Denied)

I created an Azure ARM template, which is using the Microsoft.Compute/virtualMachines/extensions in an Ubuntu 18.04 in order to execute a custom script. Once the machine is provisioned, the ubuntu user (non-root) should be able to run the custom script from the following directory /var/lib/waagent/custom-script/download/0 it receives "permission denied". I added the following lines to make sure the ubuntu user owns the file and is able to execute, but without success.
sudo chown ubuntu install_metaport.sh
chmod +x install_metaport.sh
sh install_metaport.sh
I then, changed my approach and added the following inline commands to my Azure ARM script, which worked fine. But I am trying to avoid having to copy/move the file around, and have this executed from its original directory, which is /var/lib/waagent/custom-script/download/0, but again, I end up with "permission denied" and can't figure it out how to get around this issue
cp install_metaport.sh /tmp && chown ubuntu /tmp/install_metaport.sh && chmod +x /tmp/install_metaport.sh && cd /tmp && sh install_metaport.sh
Any advise?
Thank you
Your file install_metaport.sh can be executed by user Ubuntu. You verified that by putting in another directory.
The fact that the file can be executed from another directory tells that permissions are denied at a lower level. Root folder permission limits child files permission, so most likely you cannot execute in the /var/lib/waagent/custom-script/download/0 directory. Give the user ubuntu executions rights there, and it'll work like a charm.

Laravel folder permission for not-yet made cache folders

I'm having an issue with directory permissions with Laravel when it comes to caching. Whenever it tries to upload a cache file to /var/www/laravel/storage/framework/cache/data/ it tells me that file_put_contents has no permissions.
To fix this I always do something like chmod -R 755 /var/www/laravel/storage/framework/cache/ but the problem here is that when it creates a new directory inside cache it does not inherit these chmod settings, thus giving me permission denied error again.
How can this be fixed permanently?
Edit:
Been thinking about letting it run as a cronjob regularly, but I'm not so sure that's a good way to deal with it.
You need to run chmod command with -R:
sudo chmod -R 755 storage
After installing Laravel, you may need to configure some permissions. Directories within the storage and the bootstrap/cache directories should be writable by your web server or Laravel will not run. If you are using the Homestead virtual machine, these permissions should already be set.

Linux Mint: Bitnami Xampp access issue

I have installed Bitnami Xampp on linux mint, it is installed inside /opt/
The application is unable to access(Write/Read) files and hence not able to work on it.
Any Solution Please........
Thank You
It is simple access issue. So I need to give read write access to folder and file using chmod command:-
--$ sudo chmod -R 777 opt
I have to admit that I am don't really know Xampp but with the command you mentioned above you changed the the access rights for the top level directory /opt and thru using 777 you gave basically all rights to everbody using your system. If Xampp now tries to write something, it of course can because you gave it the rights (like to anyone else).
The -R option you used in the chmod-command above means, that you have changed the access rights for all subdirectories of /opt also (recursively).
I would recommend that you change this back to the original access rights for /opt and, if you need, just change the access rights for the directory where Xampp is placed. Then Xampp should also work because it can read an write in it's own subdirectory and there won't be any harm for or from other applications from /opt because they can't access /opt/Xampp and Xampp can't access their directories.
After the previous setting
--$ sudo chmod -R 777 opt Xampp is not working with following error
PhpMyAdmin “Wrong permissions on configuration file, should not be world writable!”
Then I followed PhpMyAdmin "Wrong permissions on configuration file, should not be world writable!" and now working fine...
Thank god it saved me from switching back to Windows. That I hate.....

Workspace Settings permission denied

I'm running Ubuntu 12.04LTS.
Have unpacked Visual Studio Code in a folder owned by my user id. All vscode files are owned by my user id (user and group).
Have Node.js, npm, typescript installed via apt-get (and npm).
Visual Studio code runs fine, however File->Preferences->Workspace Settings gives this error:
Unable to create 'vscode/settings.json' (Error: EACCES: permission denied, mkdir '/.vscode').
Any ideas on how to resolve this? Where is it trying to do the mkdir?
Thanks,
Bob Wirka
UPDATE: Sudo'd mkdir "/.vscode" (literally at the root level), and chown'd it recursively to my user and group. Voila! Now I can edit the settings.
So, is there a way to tell Visual Studio Code that it shouldn't be trying to use the root folder?
Mentioned in the update by the OP but thought I'll mention it explicitly. You need to change the permissions for the folder. The following command will change the owner of the directory so that you can open it without needing root privileges.
$ sudo chown <user-name> -R <directory-name>
I had same issue on my osx. I was able to solve this issue by change the permission to read and write in project folder.
Simply type
sudo chmod 777 -R <your_app_name_directory>.
This will give all permissions to all users, groups and others for read, write, execute.
-R gives recursively permissions to all nested files folders inside your directory.
If -R is not given then it gives permissions to current directory only, not to other directories inside.
Change the permissions to your folder
sudo chmod ugo+rwx your_folder
