I have been informed about the CVE-2022-0847 vulnerability. I'm wondering what versions of Ubuntu are affected by such a bug.
What is the difference between ps -aux and ps aux? I wonder it's more than a mere matter of syntax and "portability". Which one is better to use in Ubuntu?
Despite there are some similar question, I'm interested in this specific difference.
I've just installed Ubuntu desktop 16.04 (x64) on ASUS k501U. Sometimes (not always), my mouse pointer disappears after login. I tried some solutions like Ctrl+Alt+F1 and Ctrl+Alt+F7 but they did not fix the problem. After I restart, mouse usually appears again.
It's quite an annoying issue, is there a way to fix?
I'm running Ubuntu 15.10. I installed Pyhon 2.7 through aptitude:
sudo apt-get install python
now I'm trying to install pip using this guide. I downloaded get-pip.py, then I tried:
sudo python get-pip.py
Installation worked fine, but I got these annoying warnings:
The directory '/home/administrator/.cache/pip/http' or its parent directory is not owned by the current user and the cache has been disabled. Please check the permissions and owner of that directory. If executing pip with sudo, you may want sudo's -H flag.
The directory '/home/administrator/.cache/pip' or its parent directory is not owned by the current user and caching wheels has been disabled. check the permissions and owner of that directory. If executing pip with sudo, you may want sudo's -H flag.
So I uninstalled all by the following command:
sudo python -m pip uninstall pip setuptools
And I tried a new installation without sudo:
python get-pip.py
but I got the following error:
OSError: [Errno 13] Permission denied: '/usr/local/lib/python2.7/dist-packages/pip'
How can I install pip (and wheels) in a proper way with caching enabled?
I'm running Ubuntu 15.10 on different machines.
On one of those I had to create a new user from command line (adduser) and then I added it to /etc/sudoers to give admin authorizations to that user.
Later, on another machine, I created a new admin user from System settings → user accounts, but when I check in the /etc/sudoers file, I don't find any entry for the admin user.
Why does it happen? Are users created through graphical interface listed in a different way in different files? If that is the case, what are files with the entries of new admin user created?
