All general purpose OSes (Windows, MacOS, Linux) can be changed so that the system will no longer boot completely or behaves strangely. A corrupt or full system disk, broken software packages, misconfiguration, and many other situations can cause this. Luckily, FocusRx recognizes and fixes many of these issues.
Before you begin proceed, you will first want to determine if this is actually a system issue. If your system boots fine, this is likely an application issue. We recommend you first visit the Focus support page and search for a Guided Solution using the list or the search box. These are almost always more current and correct for your hardware than HOWTOs or forum posts you might find on the web. You should proceed here only if your system does not completely boot or if you are getting warnings about missing dependencies or libraries.
Recovering an installation may be preferable because applications, settings, and other data will not need to be restored. However, like with all OSes, a badly broken system can take hours to recover and still be problematic. While a Clean Install requires recovery of data, it usually takes well under 30 minutes and can solve issues you do not have time to research or understand. For these reasons, we recommend you always keep a clean installation as an alternative and limit the time you dedicate to recovery efforts.
We encourage our customers back-up their data frequently to ensure it is safe. The best way to do this is to adjust the BackInTime settings to use an external disk. If you do this, make sure you adjust the backup filter to allow larger files and test your backups to ensure you capture all the data you need. Another handy technique is to copy your home directory to a USB drive which is described below.
/home. You should now see all user home directories on your system.
/homedirectory to the USB drive by dragging them from the left-hand file-area to the right-hand file area. When prompted, select
copy. Do NOT move the directories as this could harm your system!.
Because of file permissions, you may not be able to copy all files. When this happens, it may be helpful to run Dolphin as root. One can add this capability like so: Click on
[Hamburger Menu] > Configure Dolphin… > Services > Download New Services…. Then search for and install "Open Dolphin As Root".
Sometimes the system will boot but drop to a BusyBox Shell as shown below.
This frequently results from a corrupt file system, as detailed by this Ask Ubuntu ticket. The solution is to enter the command
exit into the shell to report the corrupt file system. You may then repair it using
fsck <device-file> as shown below.
After the file system repair is complete, type in
exit to reboot the system. If the repair was good (which it usually is), the system should now boot normally.
Focus systems have a recovery tool called FocusRx. This can directly resolve many issues:
/bootpartition is too full and fix it
You can run FocusRx as shown below.
Advanced Optionsto select a different kernel if available.
Startup Menu > Kubuntu Focus > FocusRx.
[ctrl][alt][f2]to get a virtual terminal. Sign in as your user and then enter
Please Download the ISO Disk Image and create a bootable, live USB. Then return here to proceed.
Boot using the USB stick as shown below.
F2repeatedly on your keyboard.
Boot Managerfrom the BIOS options on the screen, using either the touchpad or your cursor keys.
Start Kubuntufrom the boot menu.
Try Kubuntufrom the graphical prompt.
1. Use the live USB to boot into the Try Kubuntu mode.
2. If you do NOT have an encrypted drive, skip to step 3. Otherwise, decrypt it now.
3. Mount the partition on
If you haven’t yet backed up your data, please do so NOW! See the Take a Snapshot with USB Drive section above for guidance. You can find your user data under
/mnt/home/. While each subsequent step below is usually safe, each brings additional risk because of unknown system state or human error. Better safe than sorry.
5. Prepare and use
6. Once the system has successfully switch to
chroot mode, run FocusRx. See the section on FocusRx above for what this fixes.
See this article for additional details on using
Here are a few more steps you might try if FocusRx does not solve the problem:
sudo apt update && sudo apt dist-upgrade(this is also done by FocusRx).
aptitudefor ncurses-based graphical package management to install or uninstall packages that may have caused the problem. This interface can be navigated using a keyboard and/or mouse.
