Are there further info you need to analyse?

Hello,

This project is only for issues with the Ubuntu One Single Sign-On service, and the problem you describe does not seem to be directly with the sign-on service.

https://help.ubuntu.com/community/ReportingBugs has more information on how to properly report bugs.

If you need help with general Ubuntu issues you have two main choices.

The first is to rely on free support provided by the Ubuntu community. For this please visit https://www.ubuntu.com/support/community-support or post your questions directly in http://askubuntu.com/ or https://ubuntuforums.org/.

The second if you're looking for commercial-grade support, is to check out Canonical's support offerings for Ubuntu at https://www.ubuntu.com/support.

I hope this helps you find a solution to your issue.

Regards,

- Daniel

I would ask further questions.

Please provide data about wifi card product name. Use: lshw -C network Then: product
Please provide information about boot type you use - there might be a need to use Insecure Boot mode.

Thank you!

For `lshw` please see my initial post.
I am not sure what you're meaning with 'product' - Ubuntu 18.04 on a Lenovo L480?

The Laptop uses UEFI with 'Secure Boot: disabled'.

[You-Sheng Yang (vicamo)]

Please attach output of `sudo lspci -vvnn` and `sudo journalctl -b`.
