* Hello,
so yesterday I had the following problem:

At first I tried the build on docker and my desktop machine with the same result. Afterward I started to play with the configuration and finally I found out that the: 'PACKAGE_LIST_ADDITIONAL' option within the `userpatches/lib.config` file caused the error. Here is my configuration just as reference:
lib.config
```
KERNELBRANCH="branch:master"
KERNELSOURCE="https://git.linuxtv.org/media_tree.git/"
```

config-example.conf
```
KERNEL_ONLY="no"
KERNEL_CONFIGURE="yes"
CLEAN_LEVEL="make,debs,oldcache"

DEST_LANG="en_US.UTF-8"

# advanced
EXTERNAL_NEW="prebuilt"
EXPERT="yes"
LIB_TAG="master"
BOARD="nanopct4"
BRANCH="dev"
RELEASE="bullseye"
EXTRAWIFI="no"
WIREGUARD="no"
AUFS="no"
INSTALL_HEADERS="no"
BUILD_MINIMAL="yes"
BUILD_DESKTOP="no"
```

Greetings,
Sebastian
