I have solved my problem.
First I installed wine. Then I downloaded HiSuite (Huawei's official PC suite) Link to download page and installed it.
Then I had to connect my phone to a windows PC, so the HiSuite daemon was installed on the phone.
When that is done, just open the HiSuite daemon on the phone and choose connect with wiFi. Enter the code on HiSuite on the PC, and voila. Now the phone is connected to ubuntu :)
You can backup the phone, import contacts and calendar (if you have installed MS outlook), manage the installed apps, install new apps (you have to download the apk files to your computer, this cannot be done in this software). You can edit, delete and create new contacts. And you can import the pictures taken.
It took a lot of hard work before I found out how to do this. And this article helped out :)
Hope this can be of use to others. I looked at a forum that this can work on other android phones as well. You just have to have the HiSuite daemon installed on the phone.
