Hello atpersian,
have you tried
Menu>Lite Tweaks> Package System Repair
and
Menu>Lite Tweaks>Package Cache

[atpersian]

i try Menu>Lite Tweaks> Package System Repair  and get error as atach.

Can you try the Lite Tweaks>Package Cache
first, then try update, if failing try
Lite Tweaks>Package System Repair again

After this can you put the screen shot of results here https://imgbb.com/
then paste the code between IMG tags so I can see it on the forum

[atpersian]

its done

Thank You.
From the screenshot, it shows you have partially installed packages on your system, it may work to clean the Package cache then Repair it.
If not working, then try, hold down Ctrl and Alt Keys and press t, to open terminal, then type in

Code:

sudo apt-get update

enter your password when requested

then

Code:

sudo apt-get upgrade

and post any errors from the terminal output on the forum

[atpersian]

it get error on upgrade too:

In terminal -

Code:

sudo dpkg-reconfigure gconf2

if it is failing to update still afterwards try

Code:

sudo apt-get remove --purge gconf2 && sudo apt-get install gconf2

if your terminal is not accepting

Code:

&&

split in to 2 commands, entered individually, before && (first command), and after && (second command), then not using && in either command.
