Upgrading Ubuntu from 13.10 to 14.04 LTS

Hm… I tried once more to upgrade from Ubuntu 13.10 to 14.04 LTS, this time I also consulted pages at ubuntu.com and tecmint.com.

Again no success. I tried several variants of update-manager:

$ update-manager
$ update-manager -c
$ update-manager -d

The result is always the same, it says: “The software on your computer is up to date” without the expected addition “However, Ubuntu 14.04 is now available and you have 13.10”, and consequently without any Upgrade button.

Here is the content of my /etc/apt/sources (without comments):

deb http://archive.ubuntu.com/ubuntu saucy main restricted
deb-src http://archive.ubuntu.com/ubuntu saucy main restricted

deb http://archive.ubuntu.com/ubuntu saucy universe
deb-src http://archive.ubuntu.com/ubuntu saucy universe

I am giving up for now. If somebody sees an explanation, please tell me.

Thanks to Gerd who pointed me to SK on unixmen.com <http://www.unixmen.com/upgrade-ubuntu-13-10-saucy-salamander-ubuntu-14-04-trusty-tahr/>_ which explained the `/etc/update-manager/release-upgrades file. I changed Prompt=lts to Prompt=normal. And yes, that was the solution. As a comment in file itself says: “Note that this option (lts) should not be used if the currently-running release is not itself an LTS release, since in that case the upgrader won’t be able to determine if a newer release is available.”

DONE

  • Sometimes I got “Sorry, dialog action without base_params.mk” when invoking CreateHousehold from the action link in MembersByPerson summary panel.

    There was a typo in linoweb.js:

    if (this.base_params) { this.base_params.mk; }

    Had to be:

    if (this.base_params) { pk = this.base_params.mk; }

    But it was even more subtle. The API for generating action buttons is really not yet stable. But at least I start to test it in Integration Service.

  • Worked on the UploadsByController.get_slave_summary method. This will make our “quick upload buttons” needless! This is also going to stabilize the API for rendering action buttons.

    After the lessons I had yesterday and today, I want to work on this in a tested document. First I must add some demo data to uploads.Upload.

  • uploads.UploadType is again a BabelNamed.
