Bug ID: 457868
Summary: Offline updater does not check if enough disk space is
available before updating
Product: Discover
Version: master
Platform: Neon Packages
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: Updates (offline)
Assignee: [email protected]
Reporter: [email protected]
CC: [email protected]
Target Milestone: ---
SUMMARY
If the hard disk becomes full during an offline update, the update seems to
fail halfway, and then various bad things happen (e.g. kernel panic on boot if
the newest kernel could not be installed properly). If an offline update would
make the disk full, Discover should refuse to do an offline update, and instead
ask the user to free up enough space first.
STEPS TO REPRODUCE
1. Perform an offline update when the root partition is very close to full
OBSERVED RESULTS
I left my machine at the screen that said 'preparing updates'. After some time,
I noticed a kernel panic screen (something about being unable to mount root).
Booting from an older kernel (in grub) worked, and then I found out that my
root partition was full, which probably made the installation fail halfway,
leaving the system in a broken state.
EXPECTED RESULTS
If the free space is too low to perform an update successfully, the system
should refuse to perform an offline update (at least with an online update, you
have the option to free up space and fix things before rebooting).
