I just run the update from the terminal after download the anydesk from its official site with this command :
myubuntu# sudo dpkg -i anydesk-22.214.171.124bit.deb
It result an error :
(Reading database ... 268522 files and directories currently installed.)

And I searched for the solution, and found one in here.
sudo chmod -R 755 /usr/share/anydesk sudo chmod 755 /var/lib/dpkg/info/anydesk.p* sudo dpkg --configure anydesk sudo apt-get install -f
And walah, the anydesk is updated now.
