[solved] how to check the discspace needed for upgrade (from 19.3 to 20)?

[Thanks for the Fish]

Good evening

as the title says - how do I determine if the remaining discspace suffices for an upgrade (from 19.3 to 20)?
Is all well if...

Code: Select all

mintupgrade check

...doesn't complain about it?

any help is much appreciated!

How much space do you have available?
In finality LM20 will be about the same footprint as 19.3
Are you asking because you want to do an in-place upgrade?--or freshly installing over your 19.3?
You could show the results of terminal inquiries:

Code: Select all

lsblk

and:

Code: Select all

blkid

good suggestions will come

Thanks for your support!

How much space do you have available?

GParted says I have 3.43GB unused space on /
/home is a separate partition and swap is also a partition.

I believe I can save a few more GB by removing LibreOffice, Android Studio, Firefox and Virtual Box and by cleaning up other things.

Yes.

Many thanks!

/edit: on a sidenote: Is there an easy way to tell how much discspace is being cleared by removing a program including all the depenencies?

GParted says I have 3.43GB unused space on /

that's not a lot of overhead even with remote /home partition. Most of my Mints are 12 to 15gb of files on 30gb partitions
with mostly empty local ~/home directories.

removing a program including all the dependencies

careful here--you have to make sure those dependencies are not dependencies of
other apps. Mostly just uninstalling apps will not free up a lot of space. Try more productive routes first.
Look at the installed kernels (Update Manager toolbar View/Linux Kernels) I keep only two, the current active and one
previous working kernel for troubleshooting purposes.
A big directory is /var/cache/apt/archives which can be safely vacated by:
apt clean
If you use a local mail client back-up and flush out the old deleted and no longer needed emails--this can be huge.
Also look at the size of /var/log. This directory can grow quickly logging repeated errors.
See pjoter's pages regarding safe cleaning:

Scan your system with the Disk Usage Analyzer utility. The gui results can be telling

I expect 18 GB will not do it. Upgrades then to be download new stuff, add new stuff, then delete old stuff. New stuff for a new version can be up to 10 GB by the time it goes through all the work files and everything. A big spring clean is the minimum.

I presume you have the home partition after the system partition. If there is plenty of space, you could move the start of the home partition up using Gparted from the live boot but it will be very slow. Whatever you do, backup, backup, backup as all the options are at risk of failure.

Backup
Backup
sudo apt autoremove
sudo apt clean
sudo apt autoclean
Delete Timeshift directory

Delete LibreOffice etc. If you are deleting with Synaptic, you see the options remove and complete remove. The regular remove leaves the settings for use when you reinstall. The main settings you need to retain are in your home directory so are not affected.

You might clean out anything you are not using. For instance, if you never use Bluetooth, you could delete it.

Do you use PPAs or anything odd? Upgrade in place tends to fail with them. A clean install is usually the best option or delete the PPAs and related software before the upgrade..

sudo apt autoremove
sudo apt clean
sudo apt autoclean

apt clean deletes all the archived files and
negates the need for apt autoremove and apt autoclean
