Linux: Resetting External Drive Permisions to Root for access issues ( ie: USB HDD )

USB devices will need to be treated as if ONLY the root user will access.. BECAUSE....

... if non-root user owns the files... NO ONE ELSE CAN ADMIN them

here's a bash script to both reclaim ownership, then reset permisions to 777

this script accepts 1 argument, or it will process

function pausing {
    read -p "Press ENTER to CONTINUE, CTRL-C to ABORT" paused
function line {
    echo "---------------------------------------------------"
echo "update usb hdd file/folder permissions recursively"
echo "target: $1"
ls -la "$1"

echo "running chown -R root:root"
sudo chown -R root:root "$1"
echo "done.."

echo "running chmod -R 777"
sudo chmod -R 777 "$1"
echo "done.."

echo "done, listing target...."
ls -la "$1"



Linux: Apt Proxy Add/Remove


check /etc/apt/apt.conf

add/ remove Aquire::<protocol> as needed

  • /etc/apt/apt.conf
  • Acquire::http::proxy "http://[username]:[password]@[webproxy]:[port]/";
  • Acquire::https::proxy "https://[username]:[password]@[webproxy]:[port]/";
  • Acquire::ftp::proxy "ftp://[username]:[password]@[webproxy]:[port]/";
  • Acquire::socks::proxy "socks://[username]:[password]@[webproxy]:[port]/";

In Ubuntu 14.04, in order to use some commands in terminal (like apt-get) trough the company proxy, I need to do the following changes, beyond System Settings > Network > Network proxy > "Apply system wide" (shame on you, Ubuntu)


Linux: apt upgrade results in gconf2 errors

Update after initial Mint 19.1 install resulting in gconf2 errors

Update repo info

sudo apt update

Upgrade packages

sudo apt upgrade

then get gconf2 errors

So Configure dpkg....

sudo dpkg --configure -a
sudo apt upgrade
sudo apt-get install -f

Enable SSH if needed

sudo apt-get install openssh-server
sudo systemctl is-enabled ssh
sudo systemctl is-active ssh

or in one line

sudo apt-get install openssh-server && sudo systemctl is-enabled ssh && sudo systemctl is-active ssh

Clean up repos

sudo apt upgrade

sudo apt-get clean
