I have just installed PuTTY with sudo apt-get install putty command.

When I try to run it, I immediately receive Segmentation fault (core dumped) error.

How can I fix this?

Recommend you check the system software then retry.

Here's the procedure:

sudo apt-get remove putty
  • Open Software Updater and let it check for updates. If there are any, let it apply them, including reboots as necessary.

  • Then run it again just to make sure there are no updates to the updates.

Then go through this sequence of commands:

sudo apt-get update && sudo apt-get upgrade
sudo apt-get dist-upgrade
sudo apt-get autoremove
sudo apt-get clean

sudo apt-get install putty

Then try it again.

FYI, just checked the Snap Store for Putty:


And it reports there is not a Snap version available.

  • Thanks, got it working. The problem was that my package manager wasn't working properly due to incorrect repository names in /etc/apt/sources.list file. I also needed to upgrade to Ubuntu 18.04 LTS – thezin May 16 '18 at 4:59
