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
    line
}
function line {
    echo "---------------------------------------------------"
}
line
echo "update usb hdd file/folder permissions recursively"
echo "target: $1"
line
ls -la "$1"

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

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

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

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)

Initial install script for mint 19.1 post deploy

Command

Run the following command to produce system information with sensitive info <filter>'d

hosts

sudo cp /etc/hosts /etc/hosts.bak
sudo nano /etc/hosts

EDIT cloud.cfg ( if cloud-init installed )

ls -l /etc/cloud/cloud.cfg

setup@bamboo:~$ ls -la /etc/cloud/cloud.cfg
-rw-r--r-- 1 root root 3612 May 11  2019 /etc/cloud/cloud.cfg

Search for preserve_hostname and change the value from false to true:

sudo nano /etc/cloud/cloud.cfg

# This will cause the set+update hostname module to not operate (if true)
preserve_hostname: false

# This will cause the set+update hostname module to not operate (if true)
preserve_hostname: true
