Currently, the partition form stores the size as a human readable value. (e.g., 123456K, 1.1G, 1.876G, 100G). When we exit the size field (i.e., upon losing focus), we convert the value to a number of bytes and then align it up to the nearest MiB (or whatever the alignment requirement is). Unfortunately, after computing the aligned value, we turn it back into a human-readable string and store it as is. It is not okay because the conversion does not ensure that the alignment requirement is still honored. For instance, if the user types in 1.1G, we do the following: * convert it to a number of bytes -> 1181116006.4 (surprise, it is not even an integer). * round it up to the nearest MiB -> 1181745152 (this is the correct value) * transform it into a human readable string and store it as is -> 1.1G - which actually corresponds to the original value. This leads to an exception later when creating the partition: File "subiquity/models/filesystem.py", line 1841, in add_partition raise Exception( Exception: ('size %s or offset %s not aligned to %s', 1181116006, 1048576, 1048576) Fixed by storing the actual size as a number of bytes - alongside the human readable size.

subiquity & console-conf
Ubuntu Server Installer & Snappy first boot experience
The repository contains the source for the new server installer (the "subiquity" part, aka "ubiquity for servers") and for the snappy first boot experience (the "console-conf" part).
We track bugs in Launchpad at https://bugs.launchpad.net/subiquity. Snappy first boot issues can also be discussed in the forum at https://forum.snapcraft.io.
Our localization platform is Launchpad, translations are managed at https://translations.launchpad.net/ubuntu/+source/subiquity/
To update translation template in launchpad:
- update po/POTFILES.in with any new files that contain translations
- execute clean target, i.e. $ debuild -S
- dput subiquity into Ubuntu
To export and update translations in subiquity:
- Wait for new subiquity to publish
- Request fresh translation export from Launchpad at https://translations.launchpad.net/ubuntu/focal/+source/subiquity/+export
- wait for export to generate
- download, unpack, rename .po files into po directory, and commit changes
Acquire subiquity from source
git clone https://github.com/canonical/subiquity
cd subiquity && make install_deps
Testing out the installer Text-UI (TUI)
Subiquity's text UI is available for testing without actually installing anything to a system or a VM. Subiquity developers make use of this for rapid development. After checking out subiquity you can start it:
make dryrun
All of the features are present in dry-run mode. The installer will emit its backend configuration files to /tmp/subiquity-config-* but it won't attempt to run any installer commands (which would fail without root privileges). Further, subiquity can load other machine profiles in case you want to test out the installer without having access to the machine. A few sample machine profiles are available in the repository at ./examples/machines and can be loaded via the MACHINE make variable:
make dryrun MACHINE=examples/machines/simple.json
Generating machine profiles
Machine profiles are generated from the probert tool. To collect a machine profile:
PYTHONPATH=probert ./probert/bin/probert --all > mymachine.json
Testing changes in KVM
To try out your changes for real, it is necessary to install them into an ISO. Rather than building one from scratch, it's much easier to install your version of subiquity into the daily image. Here's how to do this:
-
Build your change into a snap:
$ snapcraft snap --output subiquity_test.snap
-
Grab the current version of the installer:
$ urlbase=http://cdimage.ubuntu.com/ubuntu-server/daily-live/current $ isoname=$(distro-info -d)-live-server-$(dpkg --print-architecture).iso $ zsync ${urlbase}/${isoname}.zsync
-
Run the provided script to make a copy of the downloaded installer that has your version of subiquity:
$ sudo ./scripts/inject-subiquity-snap.sh ${isoname} subiquity_test.snap custom.iso
-
Boot the new iso in KVM:
$ qemu-img create -f raw target.img 10G $ kvm -m 1024 -boot d -cdrom custom.iso -hda target.img -serial stdio
-
Finally, boot the installed image:
$ kvm -m 1024 -hda target.img -serial stdio
The first three steps are bundled into the script ./scripts/test-this-branch.sh.
