Ubuntu 20.04.01 LTS: Low Disk Space notification

ru flag

Issue:

Regularly receive a "Low Disk Space on "Filesystem root"" notification which is showing more frequently. Being relatively new to operating systems and dual booting, currently unsure of how to address this. An output of the notification: enter image description here

Information:

Some time ago, on a new PC (a HP-Pavilion Pro TP01-1023na Desktop) which came with Windows 10 already booted, the decision was made to dual boot with Ubuntu 20.04.1 LTS, although perhaps not enough space was allocated when partitioning, hence the aforementioned notification.

Having installed gparted, this is the current output:

Please note: before asking this question, the following resources have been consulted which is where the idea to install and utilise gparted came from:

Question:

Q1. Would it be possible for anyone to list or point me to a step-by-step guide to repartition (if this is the correct term?) so that there is more space for the Ubuntu boot? The Windows partition will likely never be used again, so I could completely get rid of this (unless it's a good idea to keep it).

Having been stuck with this query for some time, I would be highly appreciative if anyone could aid in rectifying this issue.


EDIT: Please see below an output from running df -h / :

Your gparted output does not help, you seem to have Ubuntu on another disk. See the dropdown list on the upper right of your screenshot. Please add output of `df -h /`.

The minimum recommended size for all Ubuntu Desktop systems from 17.10 up was 25GB (ie. since GNOME returned to the main desktop), but you have no partition of a Ubuntu capable install listed in your picture. You also say it's Ubuntu 20.04.1; which implies you've not looked at your install, or haven't applied upgrades in a year+ (https://fridge.ubuntu.com/2021/02/05/ubuntu-20-04-2-lts-released/ shows the ISO release date, but systems upgraded to 20.04.2 weeks before that date; an upgraded system will report as 20.04.3 currently and will soon change to 20.04.4, but not 20.04.1)

There is no "Ubuntu" on your disk. Are you running from an USB-stick ?

Thank you all for your inputs, and apologies for the delayed response. @pLumo please see my updated question with the output from `df -h /`. @guiverc I am slightly confused by this, when I run `lsb_release -a` I see `Description: Ubuntu 20.04.1 LTS` ; does this mean that I have neglected to upgrade my system, and should do this immediately?

@kanehekili I booted the OS from a `USB-stick`, but no, the OS is not running from this (nor a CD etc)

Your system is well behind on upgrades (*if it's a Ubuntu system as per my prior comment*) with the fact that it reports as 20.04.1 highlighting that; or problems with your system. You should look into that (esp. if box is online!), but that is not the point of this question of yours. One question per post/thread on this site.

Thanks @guiverc for highlighting this, I will address it in a new question.

@pLumo do you have any thoughts on the output of `df -h /` added to the question please? I unfortunately have not managed to rectify this issue yet - maybe I have to get rid of the boot entirely and start again with a newer version of Ubuntu?

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
