Error
I am able to reproduce, when the allocated size reclaimed for the new installation is very close to the required limits. Attaching some logs for debug purposes in case someone else takes a look. Created attachment 2058459 [details]

This is most likely an issue in the anaconda backend, which incorrectly calculates the requires space for the installation. Also I believe rsync silently fails because of missing space, therefore the target root is not populated fully, leading to this red-herring error we see here. Indeed, the backend was silencing rsync exceptions. https://github.com/rhinstaller/anaconda/pull/6006 After fixing that, it's clear that this fails on low space. So this bug report now aims to anaconda backend incorrectly calculating the required space for installation on Live Image. The calculation is done like this: def _calculate_required_space(self): """Calculate size of the live image image.""" source = os.statvfs(self._target_mount) required_space = source.f_frsize * (source.f_blocks - source.f_bfree) log.debug("Required space: %s", Size(required_space)) return required_space This calculation only considers used blocks in the source filesystem but does not account for additional space requirements during the installation process, aka metadata, journaling, or system overhead. There have been similar bugs in the past, but closed as wontfix. See https://fedoraproject.org/wiki/Common_F16_bugs#Minimum_space_for_Desktop_live_install_incorrectly_calculated I believe https://github.com/rhinstaller/anaconda/pull/6009 is meant to address this? @Adam yes, fix is contained in anaconda-42.16 This bug appears to have been reported against 'rawhide' during the Fedora Linux 42 development cycle. Changing version to 42. |
After guided shrink, the installation of the boot manager fails. See "Steps to Reproduce" for more details. Reproducible: Didn't try Steps to Reproduce: 1. Use the Debian 12 ISO to create the following partitions on an empty disk: 1. An EFI System (ESP) of ~1 GB (mounted at /boot/efi in Debian) 2. An ext4 of ~6.4 GB (mounted at / in Debian) 3. An ext4 of the remaining space (mounted at /home in Debian) 2. Complete the Debian 12 installation. Make sure it can boot. 3. Boot the Rawhide ISO. Select "Share disk with other operating system" and note that "Reclaim space" is enabled and cannot be disabled (as expected, since there is not enough space for a new partition). 4. Select to reclaim 3 GB from the ~6.4 GB ext4 partition. Actual Results: At the step "Installing the bootloader", this error message appears: > org.fedoraproject.Anaconda.Error: [Errno 2] No such file or directory: 'efibootmgr' An empty log area is displayed. Expected Results: Installation completes successfully.
