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.

[pre]

And then, to install it:

[/pre]

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:


second command adds the key:


third command updates and installs:


You were correct in thinking that the following was just a comment and not part of the command:

Argh!  Nothing, I think.  Try this:


Then


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!

Note: Trying to xenial instead of bionic    ???


xenial = linuxlite 3.x
bionic = linuxlite 4.x






See https://unlockforus.com/update-manager-l...-x-series/




Cheers!

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.
