I can’t install Samba.
This image is the error when I install.
What is the problem?
Hi there Ryota, welcome to the Opto forums.
Before installing any new packages, its always a good idea to update your repository.
sudo apt-get update
You should not see any errors doing that, if you do, then your EPIC/RIO can not access the internet via valid gateway or has a bad DNS configuration and you need to address any networking issues causing that.
You will know that the repository updated Ok as there will be no errors like you see in your screen shot “could not resolve…”
Lastly, when you do get to install samba, don’t forget to follow the guide on Installing and Configuring Samba on groov EPIC | Opto 22 Developer
