[SOLVED] running out of root space

Hi,

Running Zorin OS 15 Core installed on a 80GB drive.
I got a warning that the root partition is getting used up. It has 1.7GB available out of 14.7GB (Disk Usage Analyzer). I ran BleachBit (non-root version) and did a little cleaning. I could try the answer posted here https://askubuntu.com/questions/492054/ ... -partition but I'd like your opinion.
Thanks.

I just went to the main page to see minimum system requirements. That is quite an old post and as far as I can remember, you could only expand a linux partition if you had opted for Large Volume Management (LVM) at point of install.

When GRUB appears (if it doesn't, hold the left Shift key at boot time) how many kernels are listed prior to the current one in use - you'll need to select advanced options to find out - you just may need to remove an earlier kernel - you should really only have 2 kernels present - the current one and the last good working one before your current one. Keep us posted.

Thanks, Swarfendor.
It lists:
4.18.0-25-generic
4.18.0-25-generic (recovery mode)
4.18.0-24-generic
4.18.0-24-generic (recovery mode)

PS - I had used an old article to set partition sizes on installation: http://linuxbsdos.com/2012/07/23/dual-b ... -drives/2/

OK, can I take it that the current kernel is newer than that first one you gave me, 4.18.0.25 - you can find the current kernel number in two ways:

In a terminal:

Code:

dmesg | grep Linux

Synaptic Package Mananger - just search for kernel and you should get the current version listed - if this is greater than 4.18.0.25, delete the earlier kernel (ending in 24):

https://linoxide.com/booting/remove-old ... boot-menu/

I don't see anything newer than 4.18.0-25.

From terminal output:

I think your report is just stating what is currently running - does the earlier kernel still show up in GRUB?

Only under Advanced Options it shows, like before:
4.18.0-25-generic
4.18.0-25-generic (recovery mode)
4.18.0-24-generic
4.18.0-24-generic (recovery mode)

OK, Open Sofware and in the search box enter 'linux-image' without the quotes and see if the 24 shows up in there - highlight and remove.

Didn't find it in Software but found it in Synaptic Package Manager.
Seems that it wants to remove one image but install an unsigned one in its place. I didn't go ahead with the change since I'm not sure I did this right. Should I go ahead after all?
Thanks.

That seems odd to have an unsigned kernel wanting to be installed - will need to delve further.

What happens with sudo autoremove? Don't apply the change without posting back what it states it is going to remove!

sudo apt-get autoremove

OK, remove with:

Code:

sudo apt-get remove linux-image-4.18.0-24-generic

Keep us posted.

Thanks. I uninstalled and reboot (Software Updater popped up and asked me to restart).
GRUB showed the 24 version still there (seems it installed the unsigned version as it had previously stated). I confirmed using Package Manager (screenshot attached).

To avoid cluttering the prior post, I'm pasting here the results from terminal after running uninstall (in case you want to see them):

Before we go any further, when you boot into the 25 image I trust this runs correctly? If so use the apt-get command to remove the unsigned image.

Done. Package Manager doesn't show the image any more. Thanks.
Still at 2.1GB remaining root space but at least that is one redundancy gone.

PS - I started version 25 using the Advanced option in GRUB to make sure I am in 25. Then tested VLC, Firefox, Libre, a game (Ur-Quan Masters ). They all ran fine. Then I went ahead with the terminal command.

Wonderful! Can we mark this thread as [RESOLVED]?

Oops. Sorry. Thanks for reminder.
