Texmaker Shortcuts not working on Ubuntu 16.04

Install the Qt5 version of texmaker (at this date it is the one you get from ubuntu-software-center) and always run it from terminal using:

env UBUNTU_MENUPROXY= texmaker

or (a permanent solution)

Edit texmaker:

Open nautilus as root:

sudo nautilus

Navigate to usr/share/applications/texmaker , right click on it, properties, and change on Command texmaker %F by env UBUNTU_MENUPROXY= texmaker %F `

You don't have to install the older version, you just need to remove the appmenu package for QT5:

sudo apt remove appmenu-qt5

P.S. I am not sure if it can cause problems for other applications on your system. It didn't cause any problem in my end.

Regarding solution 2 of Vitor, you can also edit the launcher shortcut to TexMaker:

/usr/share/applications/texmaker.desktop

and change the line

Exec=texmaker %F

to

Exec=env UBUNTU_MENUPROXY= texmaker %F

from terminal:

sudo -H gedit /usr/share/applications/texmaker.desktop

you will see

[Desktop Entry]
Categories=Office;Publishing;Qt;X-SuSE-Core-Office;X-Mandriva-Office-Publishing;X-Misc;
Keywords=Editor;Latex;
Exec=texmaker %F
GenericName=LaTeX Editor
Comment=LaTeX development environment
Icon=texmaker
MimeType=text/x-tex;
Name=Texmaker
StartupNotify=false
Terminal=false
Type=Application

Now change the line

Exec=texmaker %F

to

Exec=env UBUNTU_MENUPROXY= texmaker %F

and then save and exit

The command

sudo apt remove appmenu-qt5

Worked for my fresh ubuntu 16.04 installation.

Create an alias in the .bashrc or create the file ~/.bash_aliases and define the alias:

alias texmaker='env UBUNTU_MENUPROXY= texmaker'

save it, exit and source it. From the home directory, do:

$. .bashrc

$. .bash_aliases

Done. Now opening Texmaker from the terminal will work perfectly.

Note: In a way it's very similar to @Vitor Abella's method.

The problem seems to be Qt5 and setting UBUNTU_MENUPROXY did not fix it for me on Ubuntu 16.10 for me, so here is my solution:

• Remove Texmaker: sudo apt-get remove texmaker texmaker-data
• Download the latest Debian version of Texmaker from: http://www.xm1math.net/texmaker/download.html#linux (In my case, I downloaded texmaker_debian_jessie_4.5_amd64.deb
• Install it: sudo dpkg -i texmaker_debian_jessie_4.5_amd64.deb

Note: the package might have some dependencies like libqt4-opengl and libqtwebkit4 that you might have to install manually

In case of Ubuntu 16.10, I have installed version 4.5 for Ubuntu 14.04 and shortcut are working. I suppose the other versions for Qt4 will work too.

I had the same issue with ubuntu 16.10, and adding the env UBUNTU_MENUPROXY= to /usr/share/applications/texmaker.desktop did not work. Nevertheless, since Ubuntu 17.04 the problem seems to be gone - even without the env UBUNTU_MENUPROXY=, hotkeys work for me in Texmaker.
