Ubiquity: Require 25 GB disk space. And document minimum required disk storage and setup partitions details.
- I'd say that miminum 2 GB free disk space should be left in the root partition after the installation + apt-get dist-upgrade, in order to install further upgrades, and to install another desktop environment. Based on the disk usage analysis below, that means 25 GB for Trisquel 11. Keep in mind that Trisquel 12 will consume more disk space for the root partition.
- I think it would be fair if users could define how big their /home/ should be (with or without LUKS in a LVM container) during the installation by simply adding a value instead of having to set up the partition tables manually (because currently it is not possible to modify the default partition setup in the installer).
Detect minimum disk space required by the Trisquel installer
- Created a small VM and installed Trisquel. The installer says that it requires 15.9 GB
Default Trisquel installation
- "Download updates while installing Trisquel": Yes
- "Encrypt the new Trisquel installation for security": Yes
- "Use LVM with the new Trisquel installation": Yes
14,9 GiB (15.9987516.1061 GB) -- default in virt-manager
- Created a VM with 14,9 GiB (14.81 GiB = 15.902116 GB, but only one decimal is allowed in virt-manager)
- The installer crashed at the end of the installation:

After upgrade:
Conclusions
- Users can choose to install all the system on root partition if they want to use the smallest disk space possible, selecting "Something else".
- Ubiquity will not take upgrades into account when calculating the installation used disk amount, don't aim to that number or you'll have issues.
- Ubuntu and Trisquel do not share the same disk partition recipe, that is not a bug but a feature.
- We should document¹ the required disk usage for out installation mentioning both options,
- using the default partition recipe
- installing all in the root partition.
So users avoid hitting this low numbers and issues when they are not aware how the default partition recipe works.
