core dumped — это не ошибка сегментации.
ошибка сегментации — это segmentation fault
У Вас как?
А core dumped — означает, что произошла какая-то ошибка в программе и программа аварийно завершила работу, но успела сбросить информацию содержимого памяти для дальнйшего анализа. *Сбрасывается дамп в файл core.

Resolving Segmentation Fault (“Core dumped”) in Ubuntu
This error may strike your Ubuntu at any point at the moment. A few days ago when I was doing my routine work in my Ubuntu laptop, suddenly I encountered with an error “Segmentation fault ( core dumped)” then I got to know that, this error can strike you Ubuntu or any other operating system at any point of the moment as binaries crashing doesn’t depend on us.
Segmentation fault is when your system tries to access a page of memory that doesn’t exist. Core dumped means when a part of code tries to perform read and write operation on a read-only or free location. Segfaults are generally associated with the file named core and It generally happens during up-gradation.
While running some commands during the core-dump situation you may encounter with “Unable to open lock file” this is because the system is trying to capture a bit block which is not existing, This is due to the crashing of binaries of some specific programs.
You may do backtracking or debugging to resolve it but the solution is to repair the broken packages and we can do it by performing the below-mentioned steps:
Command-line:
Step 1: Remove the lock files present at different locations.
Step 2: Remove repository cache.
Step 3: Update and upgrade your repository cache.
Step 4: Now upgrade your distribution, it will update your packages.
Step 5: Find the broken packages and delete them forcefully.
Apart from the command line, the best way which will always work is:
Step 1: Run Ubuntu in startup mode by pressing the Esc key after the restart.
Step 2: Select Advanced options for Ubuntu
Step 3: Run Ubuntu in the recovery mode and you will be listed with many options.
Step 4: First select “Repair broken packages”
Step 5: Then select “Resume normal boot”
So, we have two methods of resolving segmentation fault: CLI and the GUI. Sometimes, it may also happen that the “apt” command is not working because of segfault, so our CLI method will not work, in that case also don’t worry as the GUI method gonna work for us always.
