Just received an invitation from the UbuntuOne service. I took my 2 Gb. Registration, installation caused only two difficulties.
During the installation of the client software, the error “Could not find package 'ubuntuone-client'.” Appeared. It belongs to the known issue category. It is necessary to run the installation again.
After installation, the client stubbornly refused to run. A reboot has helped.
I hope these simple tips will help save some time. I apologize in advance if the topic has already been voiced.
