Apt full-upgrade fails because of gzserver

Hi everyone,

I’m trying to follow the MoveIt tutorial in a rosject, but when I try to upgrade the system it fails with the following error message:

After this, the package remains broken and apt can’t be used.

Does anyone know why this happens and how to fix it?

Hi @ceranco ,

Welcome to the Community!

Could you please copy-paste the entire error as **text** and not as an image here? Console outputs can be copy pasted as text strings!

Also, please inform what command you used that got you this error. That would help us give you a favorable if not tested solution.


The commands are:

sudo apt update
sudo apt full-upgrade

The sudo apt full-upgrade command fails with:

Errors were encountered while processing:
E: Sub-process /usr/bin/dpkg returned an error code (1)

Try to avoid this command.
