I can add a note or annotation in English language while reading a pdf file in WPS PDF. But when I try to add a note in Bengali language some square boxes appear instead of showing it in Bengali.

Besides, if the title of the pdf file is in Bengali, it also shows some boxes instead of showing the actual Bengali text.

I tried Changing the font (which supports Bengali, e.g. Jamrul) in settings, but it didn't work.

Now, I don't know wheather this problem occurs with other languages. I installed WPS OFFICE from the original deb file downloaded from the official website.

Special Note: I am able to write in Bengali in WPS Writer, LibreOffice Writer and Notepadqq.

I have installed WPS-Office from https://flathub.org.

When I open WPS-Office an error message is shown saying: Some formula symbols might not be displayed correctly due to missing fonts symbol.

Now, how can I solve this problem?

When I try to install Ubuntu 20.04 on my Dell Inspiron 5558 laptop, I get can't open /dev/sr0: No medium found error when GRUB tries to load "Install Ubuntu 20.04".

I have seen similar kind of problem with Ubuntu 11.04 in this post: How do I fix “can't open /dev/sr0: No medium found” on USB boot?. But that didn't work for Ubuntu 20.04: in fact, I tried pressing F6 and my PC automatically checked some information and I was able to install Ubuntu 20.04 at first. But when I restarted my PC after installing, it still had that booting problem issue and pressing F6 didn't work then. Also txt.cfg file of Ubuntu 20.04 doesn't match with Ubuntu 11.04.

I have also tried using other Linux Distro ISO files, re-downloading the ISO files, changing my installation medium (pen drive), changing BIOS/UEFI boot mode and also resetting the CMOS to hard reset the BIOS, but none of those worked for me and I figured out that the problem is with my ISO file. But, I don't know how to solve this issue.

Previously, I have installed Ubuntu 18.04 in this same PC without any problem. But suddenly Ubuntu 18.04 installation also gives the same kind of error message (this also happens with other Linux Distros).

My PC was manufactured with Ubuntu as default OS, so I shouldn't get this type of error (but I don't know why I am getting this error). I will have to go back to Windows if this issue doesn't get solved because I can install Windows on my PC without any problem.
