installed Ubuntu 21.04 but then it got broke and i installed Ubuntu 20.04 alongside 21.04 ant then moved all my data from 21.04 to 20.04 ant then removed 21.04 by Gparted. now i just want to expand my 20.04 main partition by unallocated space which used to be 21.04 place. the problem is that i cant do it because i have to unmount the partition from a live disk. when i open Gparted to resize the partition, i cant unmount it because it seems it already happend and so i cant expand my partition? please help me.

I just installed Ubuntu 20.04.01 L.T.S and after restarting it, Dock and all the desktop icons are disappeared and desktop is empty! but i can reach Dock by clicking on Activities on front left of the screen but it doesn't still bring my desktop things back. when i go to appearance setting, Dock is off. how can i bring everything back to normal...?

Edit: I finally brought back my Dock by searching in Askubuntu.com but Desktop files and icons are still disapeared and i even installed Mate-Tweaks to enable desktop icons but whenever i get to it check enabling desktop icons, it doesn't apply anything and if close and then open it again, there is no sign of any change. its like something in root of system or base of ubuntu is wrong! please help me!

I am using Ubuntu 20.04.01 L.T.S and after a while installing it, WhatsApp web Persian fonts changed to something really annoying, and the problem is I don't know whether its from Ubuntu, or WhatsApp web because I tried with another browser but nothing changed.

Can anybody help me change this bad font to another better Persian/Arabic font? Look at the picture:

When I use locale command, the output is:

    LANG=en_US.UTF-8
    LANGUAGE=
    LC_CTYPE="en_US.UTF-8"
    LC_NUMERIC="en_US.UTF-8"
    LC_TIME="en_US.UTF-8"
    LC_COLLATE="en_US.UTF-8"
    LC_MONETARY="en_US.UTF-8"
    LC_MESSAGES="en_US.UTF-8"
    LC_PAPER="en_US.UTF-8"
    LC_NAME="en_US.UTF-8"

after installing ubuntu, i tried to enable livepatch but first i faced this error:

    error executing enable: cannot enable machine: bad temporary server status 500 (URL: https://livepatch.canonical.com/api/machine-tokens) server response: machine token already exists        

so i did sudo rm /etc/machine-id /var/lib/dbus/machine-id && sudo systemd-machine-id-setup and then sudo rm /etc/machine-id /var/lib/dbus/machine-id && sudo systemd-machine-id-setup but it brings me new error after i tried to enable livepatch again:

error executing enable: failed to read machine-id

I wanted to remove gnome-help so i removed gnome-user-docs but then the icon of gnome-help is still on my desktop but it doesn't have any document to show and even terminal can detect gnome-help is still exist. is there any way to remove it completely? because it's a little annoying.

I have switched to Ubuntu for about a year. when i used windows,... i didn't use to have different partition for movies/photos and i used to library folders in C:\ and so it was fine for me when i only created /home partition while installing Ubuntu and when its down, i just moved my movies to /home/user/Videos and photos and documents to /home/user/Pictures .../Documents and ... . but in this past year who ever i invited to Ubuntu said that they are using different partitions for movies/pictures/documents/music and they don't want to use directories for that. so my question is can we create something like /home but only for movies, i mean only a different and empty partition that mounts like a Usb or hard? please help me with that so i can increase Gnu/Linux users in my family :)

I am using Ubuntu 20.04. I wanted to install Unity-tweak-tool, but a few seconds after it began installing I canceled the installation and then an app was added to my launcher and it's mostly like "nautilus" with the name "Files" and a purple icon and different customization and background.

I want to uninstall it or at least remove its icon. I have searched "unity-tweak-tool", "Files" and in /usr/share/applications for its icon to remove and the command: dpkg --list, but none of them exist.

The app's icon and name:

The left one is this new app and right one is nautilus:
