How to remove files to add space to root

[bradrar]

I only have 512mb left in my root and it's making my pc go slow. I tried doing all that is in here : https://easylinuxtipsproject.blogspot.c ... t.html#ID1

I also tried sudo apt autoremove but It still is not enough. I get this problem everytime I update linux mint. I think that this is the problem but I don't know how to address it.

I also got this problem everytime I open update manager

Code: Select all

An error occurred during the signature verification. The repository is not updated and the previous index files will be used. GPG error: https://dl.winehq.org/wine-builds/ubuntu bionic InRelease: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 76F1A20FF987672FAn error occurred during the signature verification.

They have been ignored, or old ones used instead.

I tried this:

Code: Select all

cd $HOME
rm -r .wine
rm .config/menus/applications-merged/wine*
rm -r .local/share/applications/wine
rm .local/share/desktop-directories/wine*
rm .local/share/icons/????_*.xpm

But it is still there.

Two problems:
1. PC is slow because 512MB left in root.
2. update manager gives me that error above.

I don't put many softwares inside my linux mint. only the ones I need, e.g.

• visual studio code
• mongodb
• vlc
• spotify
• chrome
• transmission

other than that, I have pictures and videos and files saved in the documents,downloads, and video folders. but is not related to root.

Can someone help ?

Try

Code: Select all

sudo apt clean

to clean up your apt archive.

Also if you use Timeshift with it's default settings, it will save the snapshots under root. If this is the case, delete some of those.

Please post also the output of

Code: Select all

df -h

You're saying you also removed old kernels, is that true? Old kernels are a common cause of too little space left in root.

No, if your home is on a separate partition.
Yes, if not.

Hi bradrar - - can you clarify, if you have attempted to Remove Any Older kernels ?
& if so - then what method that you tried to utilise ?.
also that you are using the later version of LM19x ? - - as this version is known, for this particular error.

[Hoser Rob]

If you do remove old kernels don't remove all of them, always leave the last one that worked.

You can also look in /var/log to see if you havbe any huge log files, which also indicate something else to look at.

There may also be some big bit of app software you don't use like gimp that can be removed.

You can see what packages are using the most space if you install debian-goodies. Then run in the terminal

Code: Select all

sudo dpigs

which will list the 10 biggest ones. If you want more use eg.

Code: Select all

sudo dpigs -n 12

to list the biggest 12.

NOTE: be careful deleting packages like this, Linux is highly modular and you may delete something needed by another program.

P.S. another thing you get with debian-goodies is checkrestart, I use that all the time when updating. There's a common misconception that there's no need to reboot Linux after an update unless it's a kernel. If you run sudo checkrestart after updating it'll say if a package is still using old libraries, which can be a security risk.

Hello, I have removed the old kernels from my system, This is the code i used:

Code: Select all

dpkg-query -W -f '${Version}\n' 'linux-image-[^g]*'|sort -u|sed -e '/^$/d' -e 's/\~[^~]*$//' -e 's/\.[^.]*$//' -e "/$(uname -r|sed 's/-generic//')/d" -e 's/.*/linux-*-&*/'|tr '\n' ' '|xargs -r sudo apt-get remove --purge -y

This was mentioned to me by gm10 because last last month, my fileroot system is full.

I think that I am using later version of LM19x. because I didn't do any major update, all I do everyday if I turn on my PC is click the package manager and install all updates. That's it

I tried sudo apt clean, nothing changes.

also here is the output.

Why is it saying command not found? Did I delete some important package or something?

Yes, if not.

Home is on separate partition.

[philotux]

Code: Select all

/dev/sda6        12G   10G  1.2G  90% /

Still looks quite full.

You could try running Disk Usage analyzer (baobab) to get a graphical overview of your disk usage and hopefully identify what is taking up the space.
And honestly 12GB for a root partition is rather on the smallest side. I believe the recommended size for a Mint root partition is in the region of 25-30 GB.

[bradrar]

You're saying you also removed old kernels, is that true? Old kernels are a common cause of too little space left in root.

I removed old kernels . I did that with this code:

Code: Select all

dpkg-query -W -f '${Version}\n' 'linux-image-[^g]*'|sort -u|sed -e '/^$/d' -e 's/\~[^~]*$//' -e 's/\.[^.]*$//' -e "/$(uname -r|sed 's/-generic//')/d" -e 's/.*/linux-*-&*/'|tr '\n' ' '|xargs -r sudo apt-get remove --purge -y

I asked this last time here: viewtopic.php?f=90&t=277572

So far, here is what I did:

Code: Select all

apt autoremove
apt clean

Code: Select all

dpkg-query -W -f '${Version}\n' 'linux-image-[^g]*'|sort -u|sed -e '/^$/d' -e 's/\~[^~]*$//' -e 's/\.[^.]*$//' -e "/$(uname -r|sed 's/-generic//')/d" -e 's/.*/linux-*-&*/'|tr '\n' ' '|xargs -r sudo apt-get remove --purge -y

clean out old logs:

Code: Select all

sudo rm -r /var/log/*.1 /var/log/*.gz /var/log/*.old /var/log/journal/*

No, you need to install debian-goodies for running those commands:

Code: Select all

sudo apt install debian-goodies

That's what I'm thinking, too.

I am looking at Disk Usage analyzer now.



here is inside usr:


I don't really know how to approach this as I might delete some important files.

Should I reinstall my linux mint and make it 40GB?

[bradrar]

Code: Select all

$ sudo dpigs
274301 linux-firmware
238797 spotify-client
199433 google-chrome-stable
195699 wine-stable-amd64
190005 code

167065 linux-modules-extra-4.15.0-45-generic
157154 libgl1-mesa-dri
143544 libgl1-mesa-dri

I thought I deleted wine? Why is it there? also, Spotify is not On right now. Is that normal?

[Moem]

That would help, but you could also boot from a live DVD or USB and then use GParted to make the existing partition bigger.

If doing that is not a big issue for you then I would say YES With 12 gb you're running out of gas

do you know any resources that I can follow to make my partition bigger?
