Yes, with a broken held package, nothing can be installed or removed- Normally. However, removal of the Broken package can be done- as long as we ID it.
What command did you FIRST try running to install codeblocks in the first place?
Was it
sudo apt-get install codeblocks
If so, can you try
sudo apt install --reinstall codeblocks
it gaves me the same error so i think i installed it via .deb o .rpm file
And
sudo dpkg --remove --force-remove --reinstreq
does not work?
IF not… let’s break some locks.
sudo rm /var/lib/apt/lists/lock
sudo rm /var/cache/apt/archives/lock
Test that we broke the locks with
sudo apt-get install synaptic
BTW, only .deb files on this distro- APT cannot install .rpm files. Those are for a different package management system.
nothing happend same error, btw i readed online that ubuntu can also install rpm files and i know that zorin is based on ubuntu 18.04 LTS
Literally, this made my jaw drop.
ok…
Choose your method: You can use the GUI approach with terminal command
pkexec nautilus
If using Zorin Core
OR
pkexec thunar
If using Zorin Lite.
Navigate to
/var/cache/apt/archives and search that directory for ANY codeblocks files and remove them.
Then navigate to
/var/lib/dpkg/info
and search for any codeblocks files and remove them, as well.
You already removed the locks
So— Reboot the puppy to ensure a clean start.
Then try installing Synaptic from terminal after booting up.
" btw i readed online that ubuntu can also install rpm files and i know that zorin is based on ubuntu 18.04 LTS"
Don’t know where you read that but… No. It is only possible to install .rpm packages on Ubuntu if you use “alien” to convert the package to a .deb file- but otherwise, .rpm cannot be directly installed on Ubuntu. Or on Zorin.
i tried ur command it gaves me the following error
Unable to init server: Impossible to connect: connection refused
(nautilus:8080): Gtk-WARNING **: 10:58:19.an another number: cannot open display:
p.s i deleted the last number before gtk-WARNING bcs i think thats my ip
p.s (2) oh ok so that was fake
Are you using Zorin Core or Zorin Lite?
idk i think core btw i typed release -a and it gaves me Distributor ID: Zorin Description: Zorin OS 15.3 Release: 15 Codename: bionic
ok im quite sure it is core bcs i got gnome desktop enviorment
I am honestly at a loss. The commands above to resolve the broken package should have worked. I have faced this problem dozens of times and never had such issues.
But Nautilus failing xhost has me baffled.
The GTK warnings can be ignored- they only deal with the Window Skinning. It does not display your IP or anything, but also would not stop Nautlius from running.
What happens if you open “Files” and run Nautilus normally?
bruh yesterday i trayed for over 3 hours i rebooted at least 20 times but nothing i tried to install cerebro yesterday so i think something goes wrong btw it gaves the same error of Gtk-Warning blah blah
Well, at this time, you at least have access to all your files, right? You can access Nautilus normally?
If you have duplicity (It comes with Zorin) and is listed as “Back ups” - If this was me on my computer, I would back up my personal files (save back ups on seprate partition or drive or cloud) and Wipe and reinstall Zorin at this point.
yeah i was thinking to do so but i wil wait for other help thanks for ur patience bro
I understand. But I would encourage you to make back ups while you wait. 
Personally, I just compress my essential files in Home Folder about once a week or so and save it to USB. Then if it comes down to it, I can wipe and reload on short notice without really losing too much.
After working on a project or finishing a project, I back up those folders by simply adding what I completed or created into the compressed files on the USB (Drag and Drop) so everything is pretty backed up, painlessly.
The combo of teh dpkg locks not releasing in spite of us removing the locks, the other commands failing AND the file manager failing to connect all gives me pause for hope, sadly. I will keep an eye on this thread.
yeah i should do the same thing too but i have a lot of files,c++ programs, screenshots and other stuff that togheter it weights at least 40 gigs and i also personalized gnome and i wan’t to do all that things again
Yes, I understand that. That first back up can take a while, though adding new or changes later are fast.
And I personalize my Zorin Desktop- Heavily. Very heavily. I had to develop tricks over time to make reinstalling easier. Including a reinstall checklist of what to adjust, fix, change, modify… turning off overlay scrollbars and what gets exported in ~/.profile… It helps a lot when something puts a reinstall into Looming view.
I hope this side topic helps you in the future, at least. If nothing else, during the time you are waiting, you can make that time useful. And if you must reinstall- Install Synaptic immediately. That Synaptic broken package fixer would have come in handy.
For me, personally, the dpkg errors are not following what should happen and the Nautilus init error was the deal breaker that made me lose confidence in your current build. Something deeper is affected.
ok u convince me im gonna wipe evrything
sorry me but idk how to reset zorin could you tell me how to do that? (yes i’m a noobie in linux i use it just for few months)
Once you have completed the back ups as covered above, you can install Zorin from your Bootable Media. If you still have the media you used to install Zorin, you can use it. Or you can re-download Zorin 15 from this server using the download button at the top of the page.
I prefer unetbootin for creating a Bootable media. Many Windows users prefer Rufus on Windows.
On each, you need to only follow the prompts.
Then boot into your Bootable media by hitting F12 or F8 Or F10- depending on your manufacturer, It usually says which to press at the boot splash screen to change the boot order.
From the Zorin Demo disk Boot, you can then move forward to Try or Install Zorin OS.
You can select Install Zorin OS once it loads. This will open an installer window- the Ubiquity Installer, which asks you for keyboard and language settings. Location is next, then it asks for the type of install.
At this point- You have a choice:
1.) You can choose to install Zorin alongside of your existing Zorin. What this will afford you is access to all your files- Let’s say that for some reason, you do not want to hassle with a massive back up- This will cause you to be able to load Zorin, then access the partition that has your files on it, and you can move them to your new partition at your leisure as time allows.
This is a viable option, but I do not recommend it for many obvious reasons… But it could help you if time is pressing or 40 gigs is too much to move around all in one go.
In future, once you have moved everything over you want to keep, that partition can be removed (Will require remaking grub, so a new thread will be needed for that). This will put your installation back to only one full partition instead of it being divided between two partitions.
2.) Install Zorin, removing all previous installations. This will delete all your files.
On either, the installer will offer prompts each step along the way, so those actions should be painless. Though you may have some bored moments waiting on it to run.

thx dude i know i’m stressing u, btw i just go to windows and formatted the partition and reinstalled zorin using my old USB where it was already installed, i used balena to create the bootable media, btw i got a unlimited drive space (i got a school account) and so i uploaded all my files there so i got a backup and from now im gonna save evrything there
