I spent several hours - rolled into days trying to sort out the updates; including reinstalling Linux Lite several times, and till no luck with the updates installing.

Another thing I've noticed; whenever I tried the reboot (after I'm instructed to remove the USB drive), press enter key, I get an error, whereby the years keeps scrolling and won't stop until I press the power/off button on the laptop keyboard.

It's a Dell Latitude E-6220 laptop.

How do I know if my Windows PC has UEFI?

In Windows Search, type msinfo or msinfo32 and launch the desktop app named System Information. Look for the BIOS Mode item, and if the value for it is UEFI, then you have the UEFI firmware. If it says BIOS Mode Legacy, then that’s the firmware you’re running.

Secure Boot is supported, but unless you know exactly how to handle it, it is a P.I.T.A. at best so I am going to say...you must disable Secure Boot to enable stress free computing.

Some helpful snippets from the latest Help Manual:

Alternatively, you can use the dd command: sudo dd if=linux-lite-7.6-rc1-64bit.iso of=/dev/sdx bs=4M where 'x' is the letter of your usb stick. In linux to find out the letter of your usb stick, open a terminal and type: df -h It is usually listed as 'media' or similar. Please see the built in Help Manual if you require a more detailed explanation of this procedure.

A good, simple point and click USB ISO burner is https://www.balena.io/etcher/ or https://rufus.ie/
In our testing, Etcher and Rufus (for Windows only) have proven to be the most reliable. Etcher is available for Mac, Windows & Linux.

If the screen locks during Live mode, type linux into the user box and click on the Login button (no password required)

I was going to upgrade from Lite 6.6 to 7.4. When checking the MD5 or SHA56 checksum, I found that they did not match the contents of the file. Are these iso files corrupt or is there something wrong? Tested on different servers in different countries. Also tested with the checker on the Linux Lite page but also from the command line in Linux. Both tests gave identical keys but not matching what it should be


Solved: the problem was with me. Sorry for the inconvenience

A LinuxLite user for many many years, and this is the first time I've had
an issue with updates.

I have two Dell Latitude E7270 laptops, both were given a completely
fresh install of LinuxLite v7.4 and both are displaying the same error
when I try to install the latest updates.

Any help would be greatly appreciated.
My Updates Error log is posted below.

Kind regards,
Ewan.

E: dpkg was interrupted, you must manually run 'dpkg --configure -a' to correct the problem.

New to linux, not a coder
old Dell latitude e6410 had win 7, installed linux lite via usb has been booting and working just wont update.

should i ignore error?

I’ve recently installed Linux Lite on a Dell Latitude 3120 laptop. The installation went smoothly and everything works, even the touchscreen. I was able to install all the software I use with a combination of the Lite Installer and Synaptic. However, when I installed ProtonVPN using apt in the terminal, I ended up with a choice of two desktops at the login screen; Gnome and Xfce. I much prefer Xfce.
A Big thanks to the Linux Lite team for an excellent distro.

Hello everyone,

I'm running Linux Lite 5.4 on an HP machine with BIOS Legacy. I've converted my disk to GPT and created a proper EFI partition. I installed GRUB in UEFI mode via terminal (no Live session available), but my firmware does not detect the fallback `bootx64.efi` file. I'm still booting using Legacy mode via F9, and I can't use `efibootmgr` because EFI variables are unavailable in my current session.

What I'm looking for is a way to force UEFI boot using only terminal tools, without removing GRUB Legacy or risking an unbootable system. Ideally, I want to activate a UEFI path that my firmware will recognize, even if it requires copying files manually or testing alternate bootloaders.

System info:
- **Linux Lite Version**: 5.4 (Ubuntu 20.04 base)
- **Memory**: 1.8 GiB
- **Motherboard**: HP 80BF
- **Kernel**: 5.4.0-216-generic
- **Graphics Chip**: Intel HD Graphics (x5-E8000)

Any guidance, script, workaround, or documentation that could help me achieve UEFI boot without a Live USB would be greatly appreciated. Thanks in advance!

Hoping someone can help -- I've not been able to update for a while now. System works well other than that. Also included hardinfo.

And was wondering if there was some sort of a checklist published that might help the user troubleshoot updates? Something like common failures, solutions to try. Reading various solutions, I see recommended solutions that I really do not understand.
Thanks to all...

Hello, loaded and installed Lite from USB. Gave me an error at the end of the install. Laptop now only shows GNU GRUB prompt. Can't get out of it. I did the exit twice and gave me a startimage failed: load error. I should still have Windows on the machine. I tried boot order to do computer first and also tried USB first too. No difference. Would like to be able to use either Linux Lite OR Windows at this point. But stuck at the grub prompt. Please help. Thanks!
