error upload program:

avrdude: ser_open(): can't open device "/dev/ttyACM0": Permission denied
Problem uploading to board. 

answer:

If you want the app to always run as root

1) Pin the application to the launcher as normal.

2) Locate the applications .desktop file which will be in either:

• /usr/share/applications/APPNAME.desktop
• ~/.local/share/applications/APPNAME.desktop
• or somewhere else, use locate .desktop|grep APPAME

3) Open with gedit:

gksudo gedit /usr/share/applications/APPNAME.desktop

4) Then change the line

Exec=APP_COMMAND

to

Exec=gksudo -k -u root APP_COMMAND

5) Save

This command will also keep your environment which is very usefull if you need to connect to others servers and use your private key.

To add a quicklist option to 'Run as root'

Follow steps 1, 2 and 3 above

If the launcher currently doesn't have any other quicklist options, just append this to the end of the document

X-Ayatana-Desktop-Shortcuts=Runroot

[Runroot Shortcut Group]
Name=Run as root
Exec=gksudo -k -u root APP_COMMAND
