Installed zorin 15.3 core but no idea how to connect to wifi

okay ...
currently, i am still with z15.3 and started this series of posts on the 16th of august originally asking how to get connected to wifi.
can't remember who but someone in the forum suggested i should try z/lite because it might be easier then core 16 was released then someone (else?) suggested i install that instead because it should might solve the wifi problem so i opted for 16.
with loads of posts going back and forth, i think i'm possibly near at the point installing 16 if i can get the laptop to install it but hey, what do i know??
i think that pretty much covers your first two questions.
as regards the third one, think i've attempted rufus, unetbootin and etcher with unetbootin finally enabling my usb to be converted to a bootable drive (i don't know how to confirm that) but obviously 16 didn't get installed so maybe unetbootin failed somehow.
with the 3 rufus (etc) programmes, i've tried to get them working a number of times all without success. in fact, i've gone back right to the start and appear to getting kicked back. all this process. is said to be an easy job ... well, could've fooled me. having said that, i don't want to give up 'cos i hate defeat.
my thanks to all of you.
that's about it and fogive my gripe.

later ...

Good attitude.

As @Aravisian said, this thread has grown big, so was useful for you to give a current situation report.

If you have Z16 on a bootable USB via Unetbootin, can you try to boot from it and do the "Try Zorin" option. That will prove the USB works or not before you attempt a full install.

The idea behind going to Z16 was to give you more uptodate drivers and kernel to see if that overcomes your wifi woes.

Is Zorin 15.3 installed or is that what we are working to install?

hi ...
no ... i'm still aiming to install core 16 which i'm presuming will delete 15.3 during the 16 install.

with 'try zorin', how does that work? do i install it on the laptop or the bootable usb drive (if its still bootable)? as with 15.3 and 16, when i download the "try zorin", do i then make sure that it goes onto what i hope will be the bootable drive or do i just make sure that it's in home/recent/download and if so, can you tell me what the code is to copy it over?

on the point of the usb drive, if i covert it to a bootable drive, does it stay a bootable drive or do i need to go through the convertable process a second or third time etc. etc. whenever i attempt an installation of any other particular programme in the future?

I think the best approach would be to take it step by step and ensure each step along the way.
First, you need to Download Zorin OS 16 as an .iso file. If you do this on Linux, it will be in your Downloads folder.
To burn this .iso to disk:

Insert the USB disk you want to burn the iso to into the usb port.
Open Unetbootin.
Click on Diskimage to select it.
Click the ... button on the far right. On the left, select Computer. Then on the right side, select /. Now, select home. Next, select your user name (Should be the only option). Next, Downloads and finally, select the Zorin OS 16 .iso
Now, click the OK button.

hi ...
first thing first ... i've already got 2 or 3 copies of the zorin-os-16-core-64-bit-r1.iso files which i downloaded a few days ago ... one of them should be fine for what i want it to do.
secondly ... my usb drive is connected to the laptop.
thirdly ... the unetbootin-linux64-702.bin file is also in the home/download folder along with the 16core iso file. each time i tried to open the bin files, it gives the following msg:
"could not display unetbootin-linux64-702.bin" ... is unknown.
there are 2 buttons ... 1) no applications exist for etc... and 2)brings me back to the home/download folder.
so i can't open the file nor click on anything else.

I strongly recommend installing unetbootin directly.

sudo add-apt-repository ppa:gezakovacs/ppa

sudo apt-get update && sudo apt-get install unetbootin

okay ...
did all that ...

right at the end, after "E: ..... basically says zorin doesn't have a release file ...
then under that, after "N: ..... says updating from such a repository can't be done securely therefore disabled by default ...
then finally another "N: ... see apt-secure(8) manpage for repository creation and user configuration details ...

Can you either post a screenshot or copy paste the entire message so we can see with repo or packages are in question?

hope this works ...

umm ... tried copy and paste (ctrl+C) but didn't work ...
does linux work with a diff. combination?

In terminal, you can Right Click to find copy or paste in the context menu.
In terminal only, you will find that ctrl+shift+c is needed, even though it is ctrl+c everywhere outside of the terminal. This is because within the code for the terminal (xterm), ctrl+c is already used for another function and it is locked in. Similarly, the keyboard shortcut to paste in the terminal is ctrl+shift+v

thank you for the copy code ....

got it ...

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.

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 ...

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

you mean, in the "Z" icon ?

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' ... ?

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.


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

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