Building dependency tree... libfreetype6-udeb:amd64 Depends on libbrotli1:amd64 < none @un H > (>= 1.0.7) can't be satisfied! Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming. The following information may help to resolve the situation: The following packages have unmet dependencies: libfreetype6-udeb : Depends: libbrotli1 (>= 1.0.7) but it is not installable E: Unable to correct problems, you have held broken packages. Then I tried to download the source code and build it myself. git clone https://salsa.debian.org/installer-team/d-i.git cd d-i ./scripts/git-setup mr checkout cd ./installer/build apt-get build-dep debian-installer make reallyclean make build_cdrom_gtk The same error occurs again Building dependency tree... libfreetype6-udeb:amd64 Depends on libbrotli1:amd64 < none @un H > (>= 1.0.7) can't be satisfied! I think this is a bug, please fix it as soon as possible.
