Bad icons display in menus

[Fraga]

Please, I'm from Brazil and I'm using Ubuntu-Mate for the first time.
The menu appears with icons like squares with a trace on it.

How can I fix It?
By the way, Ubuntu Mate is a great OS, I'm enjoying it.
Thank you.

Hi, glad you like Ubuntu Mate

I hope also to enjoy the community !

There is already a similar topic :

Menu icons not found on fresh new install 20.04

Hello! I decided to try Ubuntu Mate 20.04 LTS after years using Xubuntu. On a fresh new install I experienced an annoying error on main menu. Some icons are not found. This is a fresh new install (I used all default options in Ubiquity installer from USB pendrive). Please see this image: [menus-20-04] Any help to fix it is appreciated! P.S: I installed twice "burning" a new ISO to my USB pendrive and it still the same =/

If the fix of @24601 do not work for you @Fraga you can try reading a bit this topic.

Also, changing the icon theme can help :

Thank you for your reply. I've changed the theme as you've suggested; the best I could get:

@Fraga, welcome.

@olek already linked you to a duplicate topic which discusses this issue in detail; too much detail to be honest. As such I'm going to give you a shortcut to the short workaround:

Menu icons not found on fresh new install 20.04

Well, @lah7's workaround works, but in addition you have to do that in all *.directory files located in /usr/share/mate/desktop-directories / For exemple, take the mate-office.directory file: [WhatsApp Image 2020-07-01 at 15.10.05] As you can see, pt, sl and nl are afected and other languages are not needed, so is secure to remove all lines that start with Icon[ sudo sed -i '/Icon\[/d' /usr/share/applications/*.desktop sudo sed -i '/Icon\[/d' /usr/share/mate/desktop-directories/*.directory …

Basically, the problem is: Somebody accidentally translated icon names a while ago; the buggy applications were included in Ubuntu (MATE) 20.04 LTS; the bug was fixed; it's tough to update LTS versions of packages, so nobody patched the LTS versions of the packages for Ubuntu 20.04.1 and thus the problem continues to haunt some of us.

Plagiarized from the post I quoted above, here's the commands to rectify the issue, at least for the time being:

sudo sed -i '/Icon\[/d' /usr/share/applications/*.desktop
sudo sed -i '/Icon\[/d' /usr/share/mate/desktop-directories/*.directory
sudo update-desktop-database

This deletes the unnecessary and detrimental translations on the icon names for numerous MATE applications and desktop directories. If it works, you can thank @azardo.

It works! Thank you Gordon and @azardo. Check it:
