I was unable to reproduce it (recommended 'desktop=lxde' setting, see manual). I figure you used 'desktop=kde' (default kernel command line entry, common for all profiles); in this single case LTSP installation fails reproducibly. In the past I've tested also this case taking into account that reading a manual isn't fun for most people and thus will simply hit return; back then the KDE variant used to work as well, enough space was left. Now, the netinstall ISO image being outdated and a lot of updated packages getting installed after point release 9.4, /var/cache/apt/archives is filled up and about 100 MiB space is missing. (As LTSP mounts the server Apt cache and arch=i386 is the LTSP default, a whole bunch of unneeded packages plus the updated ones show up.) That said, a simple workaround is (if someone really wants KDE for LTSP clients): After the Debian installer reported the LTSP menu item as failed: (1) Activate a Debian installer shell. (2) Run 'rm target/opt/ltsp -rf' (3) Run 'rm target/var/cache/apt/archive/*_amd64.deb' (4) Go back to the installer gui. (5) Choose the LTSP menu item again. One could use an even simpler solution: Once the LTSP changeroot installation has started, do steps (1) and (3); the installation will run without issues. As far as Buster is concerned, the cache issue won't show up as the LTSP chroot arch will be the same as the server one. Wolfgang
