I ran add-apt-repository ppa:ubuntu-wine/ppa in docker container, but failed with the notice:
Cannot add PPA: 'ppa:ppaname/ppa'.
Please check that the PPA name or format is crrect.
Hower it worked on the host.
After googled a lot,I've tried the followings:
apt-get install python-software-properties
apt-get install software-properties-common
apt-get install --reinstall ca-certificates
and didn't work.
The system on host is ubuntu 14.04,64bit.
The image of container is based on ubuntu 14.04 from DOCKER HUB.
Can anybody help me?
