Troubleshooting

Problem

1. I can't install packages via apt-get install inside the container

2. I cannot create files or folders (no write permissions)

Solution

1. If the package is not found first apt-get update and then try again. If there is no connection check your dns settings.

2. In the container, execute once the script Rechtesetup/setpermissions.sh to gain write access in /home/fenics/shared

    cd /home/fenics/shared/Rechtesetup & sudo ./setpermissions.sh
