thank you for the copy code ....

got it ...

#133

Can you please open Software & Updates from the Zorin Menu.
Select the Other Software tab.
At the very top, UNcheck the box for cdrom://Zorin-OS 15.3 Core 64bit bionic InRelease
Once done, close Software & Updates (let it reload).

Open terminal and run:

sudo apt clean && sudo apt autoremove

sudo apt dist-upgrade

Once done, please relay any errors.

Launch unetbootin from the Zorin Menu and continue from that point in the .iso burning process.

#134

okay ... from the "Z" icon on the far left of the bar at the bottom of the screen, tapped software then updates ... all it showed was "software is up to date" ... nothing else ...

#135

The app is named Software & Updates. If you type out the whole name, just as that, it should show up.

#136

you mean, in the "Z" icon ?

#137

in the z/icon, then in the search bar at the bottom of the small window, everything i ever type in there, never seems to activate except delete what i typed in ... there is nothing i can see to 'send' what i typed in ... so i'm always back to square one .....

in what window do i have to get on screen to tap in 'software & updates' ... ?

#138

As you type, it responds automatically, there is no "enter" function.
But, for now, let's just open it from terminal to make things easier.

software-properties-gtk

#139

thanks ... okay ...
that brought up a small window headed 'software & updates' with a list ...

#140

tabs are z/software, other s/w, updates, authorisation & add. drivers .......
what should i pick ? updates ...?

#141

This one.
Then, at the top, UNcheck the box for CD:ROM

#142

done ...

will be back here in abour 20 to 30 minutes ,,,,

till then ......

#143

my mistake ... not for another 50 minutes yet ...

at the bottom of s/w & updates, choice of 3 ...
add / edit / remove ...
is it unetbootin (bin) file or the zorin iso file ......? or something else ...?

#144

None of those. Just UNCheck the box for CD:ROM. That is all that is needed in this application.
This is to solve the error about being unable to update apt from the CD:ROM.

Once that is done, please proceed with opening unetbootin and burning the .iso to your flash drive.

#145

I started to wonder if OP would be better off waiting for the upcoming Zorin 16 Lite. There would be many improvements incorporated in this new version. That way, OP can avoid upgrading OS which could be quite a number for beginners.

#146

okay ...

i've unticked the cd rom box as suggested and closed the 's/w & updates' window.

will re-attempt to open unetbootin but i think that's what i did already and didn't get very far ...

will shutdown shortly so will reply to you tomorrow.

cheers and thanks a stack for your help so far ...

hi ...

a similar alternative was suggested around the time i started this series of posts ...
z15.3 core then z15 lite then 16 core which is still ongoing as you know ...

....... if you think that z16lite will install considerably easier and faster than z16 core, then i'm willing to give it a shot whenever it is released.

#148

Since we still do not see the actual thing, I cannot vouch. But I saw much problems have been solved by going for Zorin 16 Core from 15,3 Core.
I would imagine the same thing could happen between Zorin 15,3 Lite and 16 Lite.

#149

i've not yet managed to install z16 core ... so many problems ... but i live in hope ... i have to admit, it's very frustrating at times.

am i right in thinking that the 'lite' version is a cut-down version of core?

#150

It has more or less the same apps, but the Lite uses a different desktop (XFCE) which is way more straightforward than Gnome (Core version's desktop).

#151

I would say, No. This does not describe it. Lite uses a different desktop environment that is not as Resource Intensive as Core.

Core is formulated (With Gnome) to launch apps based on productivity - much like preload. This includes having apps run in the background in anticipation of you launching it - or running prep scripts.
XFCE does not load an app in anticipation of you launching it. It only loads it if you launch it.
This makes XFCE less resource hungry than Gnome. For most apps on XFCE, they should still launch quite quickly. But some heavy apps will launch more slowly on XFCE than on Gnome, since the full app must be initialized.
Due to XFCE being lightweight though, on a new system with lots of RAM and a fast processor, XFCE would launch even the heaviest apps as quickly if not quicker than Gnome, since Gnome is also running other 'high demand" apps in the background and XFCE is not.

XFCE is not just for old computers.
