thx for your feedback the issue is core22 using kf5-5-110-qt-5-15-11-core22 or cups cups is ur printer driver

sudo snap remove kf5-5-106-qt-5-15-9-core22
sudo snap remove kf5-5-108-qt-5-15-10-core22
sudo snap remove kf5-5-110-qt-5-15-11-core22
sudo snap remove cups
sudo snap remove curl
sudo snap remove core20
sudo snap remove core18
sudo snap remove gnome-3-28-1804

or i will make new script for you ? u need to replace cups to deb package

[rafisics]

Thanks for replying. Yeah, I was thinking of removing them with sudo snap remove, but would I need to install any essential alternative after removing them? It would be great if you could configure the script considering these.

[PagalSarthak]

yes you do ok i will make a script today that meets your requirement

[rafisics]

Thanks, I would be waiting.

[PagalSarthak]

ok i make the script for u but first i want to verify that r u using KDE ?? or KDE software

[PagalSarthak]

u r are using KDE plasma or kubuntu and removing the kf5 Snap packages you mentioned could potentially lead to issues it might breaks thing too sorry for wasting ur time

[rafisics]

I am using Ubuntu 24.04 LTS, and I consciously use Gnome things.

echo $XDG_CURRENT_DESKTOP

ubuntu:GNOME

But I am not sure why I have those KDE things. Can it happen that I maybe tried testing with KDE tools and their traces are there?
No, you are not wasting my time. Can you suggest how I should verify in detail and what is safe to remove?

[PagalSarthak]

i think u try to install KDE in past i recommend not to remove KF5 buz u have app like KDE connect there is a some package u can remove and re install via repo

sudo snap remove cups
sudo snap remove curl
sudo snap remove gnome-3-28-1804

re install it via repo

sudo apt install cups 
sudo apt install curl

keep snaps and replace these packages

[rafisics]

I don't have KDE Connect installed, I use GSconnect now. Snaps are making the booting process slower.

[PagalSarthak]

if you don't use any of these then i make script for u that work fine see removing KF5 = u can't use any of these package still want to continue

As I told you, the issue is I am not sure where these KDE are used in my system. Are they standalone applications or are they installed due to the dependency on other applications? Can you suggest any way to check and verify their use and dependency?

[PagalSarthak]

these KDE installed due to dependency of

If you're using GNOME and want to remove KDE-related packages to streamline your system, you can follow these steps. Keep in mind that removing KDE libraries and applications may affect any KDE applications you have installed or any features that rely on KDE components. sudo apt remove --purge kdeconnect keditbookmarks kaccounts-providers kded5

sudo apt remove --purge kubuntu-desktop kde-plasma-desktop plasma-desktop

sudo apt autoremove --purge
sudo apt clean

I used this script. At the beginning it showed:

Stopping 'snapd.service', but its triggering units are still active:
snapd.socket
Removed "/etc/systemd/system/multi-user.target.wants/snapd.service".
Disabling 'snapd.service', but its triggering units are still active:
snapd.socket
Created symlink /etc/systemd/system/snapd.service → /dev/null.
Masking 'snapd.service', but its triggering units are still active:
snapd.socket
Removing Snapd service...
Reading package lists... Done
Building dependency tree... Done
Reading state information... Done
The following packages will be REMOVED:
  snapd*
0 upgraded, 0 newly installed, 1 to remove and 0 not upgraded.

Is it an issue that it says but its triggering units are still active?

[PagalSarthak]

na its not try snap --version or snapd --version

[rafisics]

Yeah, they are not installed. Thank you so much for your time.

[PagalSarthak]
