It seems like you're facing dependency issues while trying to install libpcl-dev on your Ubuntu system. The error message indicates that libpcl-dev depends on libvtk6-dev and libvtk6-qt-dev, but these packages are not being installed for some reason.
One solution could be to try updating your package lists and upgrading your system packages before attempting to install libpcl-dev again. You can try running the following commands in your terminal:
```
sudo apt-get update
sudo apt-get upgrade
sudo apt-get install libpcl-dev
```
If this doesn't work, you can try manually installing the missing dependencies (libvtk6-dev and libvtk6-qt-dev) using the following commands:
```
sudo apt-get install libvtk6-dev
sudo apt-get install libvtk6-qt-dev
sudo apt-get install libpcl-dev
```
If none of these solutions work, you may need to remove any conflicting packages or fix any broken packages on your system before attempting to install libpcl-dev again.
