Aramo > Ecne upgrade DIY test script (be careful!)

Bug Report Template

---

1. Goal

Test the Trisquel 11 to 12 upgrade.

---

2. Details on the script

In order to test/run the upgrade process and don't rely on trusting someone requiring to download the upgrade tool from somewhere, the idea is to build it yourself.

Please be aware, we put a lot of effort on the preparation of the ubuntu-upgrade-release source code. Still, this process has been tested only on VMs. So be careful with your data.

In order to ease the test process, it is done via a bash script, here a small summary:

1. The script installs the requirements
2. pulls the Trisquel's package-helpers repo
3. builds the ubuntu-release-upgrader source with Trisquel's changes
4. prepares the ecne.tar.gz tarball
5. if the script is executed with --run-upgrade it starts the upgrade process via text console.
6. By default the script (if not ran with --run-upgrade) only prepares everything to run the upgrade tool later.
7. Goes through the upgrade process to Ecne.

3. Current version of the script.

Create a file named build-ecne-upgrader.sh

touch build-ecne-upgrader.sh

Paste the following script on it.

#!/bin/bash

Run the script using:

bash build-ecne-upgrader.sh

4. Expected Behavior

Get Ecne upgrade from Aramo.

---

5. Warnings.

Almost no one but me has tested this script.

Please, test this out on

a) a test VM
b) a test/secondary machine with no production data on it.
c) report issues, findings or success tales.
d) under your own risk, test this out on production machines or wait until the official release.
