 # Troubleshooting
+
+## Removing packages from the PPA:
+
+### Method 1: Using ppa-purge
+In case of our stable PPA:
+```{r, engine='bash'}
+sudo apt update
+sudo apt install ppa-purge
+sudo ppa-purge ppa:thopiekar/cura
+```
+In case of our master PPA:
+```{r, engine='bash'}
+sudo apt update
+sudo apt install ppa-purge
+sudo ppa-purge ppa:thopiekar/cura-master
+```
+### Method 2: Using synaptic
+Using Synaptic you can easily see where your installed packages are from.
+In our case you can easily select the PPA and remove all packages from there.
+For more info on using Synaptic search the web for manuals. There are enough around...
+
+### Method 3: Apt-Pinning
+An easy method for advanced users is to change the PPAs priority using APT pinning.
+While choosing a low "Pin-Priority" you can even tell APT to avoid a repository, if needed.
+Using a low here will tell APT to downgrade to the Ubuntu packages whenever possible.
