My Boot is 100% full. How to clear it?

Opa3de · 07-31-2020, 01:03 PM

I'm currently using Linux Mint 19 Cinnamon 3.8.9. The command "/dev/sda1" results in a "Bash /dev/sda1-permission denied" How do I get permission to delete unwanted files? I'm new at this stuff. Thanks!

Could you post the output of the command:

Code:

df -h

/dev/sda1 isn't a command. can you explain what you were trying to do or how you intended to delete files?

usually using sudo before a command will let you do things that require root permission, but it is best to be careful how you use it.

can you run the command df -h (df reports system disk space usage -h shows it in human-readable [GiB] form instead of bytes) in a terminal and post the output

I ran df-h command and the output was "command not found." With the df command the output was a list of used/available space were this /dev/sda1 is mounted on /boot. I'm trying to delete old files from this boot. Hope this helps.

you need a space between the command df and the option -h. i believe that is probably true for most commands and options. it can helpful when you are starting out to copy and paste the command into your terminal to make sure it is correct.

whichever one you run, it would still be useful to see what the output is. can you copy that from the terminal and paste it into your reply?

if you are still able to boot into this installation, you should be able to use the kernel manager to delete some of the kernels taking up space in boot.

michaelk · 08-01-2020, 09:28 AM

From a terminal run the commands

sudo apt-get autoremove

sudo apt-get autoclean

Does that help?

beachboy2 · 08-01-2020, 09:52 AM

Opa3de,

To automatically remove old kernels in the future:

Update Manager > Edit > Preferences > Automation > Remove obsolete kernels & dependencies.

In this sequence, "automation" and "Remove obsolete....." were not listed as choices. ??

Opa3de,

That's strange because it shows up fine on my Linux Mint 20 MATE.

I tried "sudo apt autoremove -f" This command gave me a chance to free up 425M of space. However, it crashed with an error message due to "broken packages/dependencies." Thanks for your input.

cordx · 08-02-2020, 04:58 PM

i have never run autoremove with -f. you might want to try without. if you are still having trouble, it would be helpful if you could post the text of both the command you run along with the output you get as a result in the terminal.

Beachboy, it is in my Mint 19.3. I followed your instructions and made
the change! Frank you, most kindly.

Opa3de · 08-09-2020, 11:26 AM

In my effort to solve this issue, my hard drive crashed. Messages, F2= "Kernel panic-not syncing, unable to mount roof fs on unknown block." With F12,
"Please unlock disk sda5_crypt." In Post #6, sda1 is listed with 100% used. My password was always associated with sda1. I have no password set up with sda5 to unlock it. ???

I bought a new PC and will consider installing Linux 20 Mint thereon. thanks to all for your input.
