Because I ran into issues with one of the old laptops I use for youth I decided to try the route Artim suggested about selective updates since I am a newbie. I was able to install it on the problem laptop, however I have tried installing it on two other older laptops and I believe I am doing the same steps.
I followed the article I found for "update manager for Linux lite 3.x series" and initially on all of them I went ahead and tried the sudo line for the unlockforus repository which didn't work and then I found out it appears that this repository already exists on the laptops. So I went ahead and put the other sudo command in to get and install mintupdate. As I said it worked on the first laptop, but the message I am getting on the other(s) is:
WARNING: The following packages cannot be authenticated!
mintupdate-lite
E:There were unauthenticated packages and -y was used without --allow-unauthenticated
I'm not sure what I am doing different or wrong...
Might someone be able to comment and point me in the right direction should I wish to pursue putting this on select laptops?
Hi Janet,
Did you copy-and-paste the terminal commands from the web page? It kinda reads like you selected it from the unlockforus Linux Lite repository instead. The key is missing.
Code:
echo "deb https://unlockforus.com/repository/dists/xenial/ /" | sudo tee /etc/apt/sources.list.d/unlockforus-xenial.list # And add the PGP key: ~$ curl -s https://unlockforus.com/repository/keyFile | sudo apt-key add -
[pre]
And then, to install it:
[/pre]
Code:
sudo apt-get update && sudo apt-get install mintupdate-lite -y
Ahhh, when I saw that original command with the part in the model that says “And add the PGP key” I did not think this was part of the command. I very originally copy and pasted the first part before the # And... then did the second line.
Let me give it a go with what I understand above and see how I make out.
Thanks, here’s hoping it’ll work

I must be doing something wrong...
I copy and pasted exactly what you had above. Maybe I have misunderstood your steps..?
Here is what I did:
1) pulled up terminal
2) went directly to your post above and copied the full text in your first green box and inserted it in the terminal window after the $ then clicked ENTER.
3) entered my pw
4) once it completed I then copied and pasted the text from your second green box and it went through a bunch of stuff, but then finished off with the same line as I posted above regarding "the unauthenticated packages..."
What am I doing wrong?

first command adds the repository as a source:
Code:
echo "deb https://unlockforus.com/repository/dists/xenial/ /" | sudo tee /etc/apt/sources.list.d/unlockforus-xenial.list
second command adds the key:
Code:
curl -s https://unlockforus.com/repository/keyFile | sudo apt-key add -
third command updates and installs:
Code:
sudo apt-get update && sudo apt-get install mintupdate-lite -y
You were correct in thinking that the following was just a comment and not part of the command:
Code:
# And add the PGP key: ~$
Argh! Nothing, I think. Try this:
Code:
echo "deb https://unlockforus.com/repository/dists/xenial/ /" | sudo tee /etc/apt/sources.list.d/unlockforus-xenial.list
curl -s https://unlockforus.com/repository/keyFile | sudo apt-key add -
Then
Code:
sudo apt-get update && sudo apt-get install mintupdate-lite -y
And if if totally fails again, you can ask on that web page about it, or PM [member=6629]ralphy[/member] here on the forums. He will help you better than I can, and he's a really nice guy! Unlockforus was put aside temporarily while "real life" interrupted and hindered things. But I understand it's back up and slowly being updated as time permits.
I'm sorry this has been so troublesome for you! It absolutely should
not be at all!
Yay - it worked! It is 3.8 I am running so the xenial was correct for what I needed.
I did the steps that Deepthought outlined and it worked perfectly.
Thank you to all of you for helping me out here. Linux Lite OS is great and all the help I receive from forum members is "Priceless" ;D
I will bookmark this page so I know for future installs.
[member=7067]JanetBiggar[/member] That's great

As for my part, [member=6925]Artim[/member] did the work, I just cleared up a misunderstanding
[member=6629]ralphy[/member] Might I suggest a slight change on your website, by taking the
"# And add the PGP key:"
outside the code box, similar to how you have "Install Update Manager:".
It might save confusion for newbies, especially if they have learnt that $ is the normal user prompt while # is the root prompt.
