Experiences With Open Source

I just run the update from the terminal after download the anydesk from its official site with this command :

myubuntu# sudo dpkg -i anydesk-5.5.5.64bit.deb

It result an error :

Errors were encountered while processing:
 anydesk

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.
