Error while loading script

Hi All,

while i try to launch the launch.sh i get the following error massage:

Thanks for the report @chrischd83 — diagnosed. This is a locale bug, not a problem with your setup.

launch.sh's VRAM-budget block formats numbers from kv-calc.py (like 9.0, dot decimal) with printf "%.2f". Your shell is in a German locale where the decimal separator is a comma, so bash printf rejects the dot input → printf: 9.0: Ungültige Zahl and the launcher stops. (Your 9,00 GB with a comma is the same root cause.)

Immediate workaround — works right now, no waiting:

LC_NUMERIC=C bash scripts/launch.sh

That forces C-style numeric parsing for just that run; everything else (including UTF-8 output) is unaffected. The booted container itself was never affected — this only hit the pre-boot budget print.

Permanent fix: PR #160 adds export LC_NUMERIC=C near the top of launch.sh so it's locale-robust out of the box. Once it merges, git pull and the plain bash scripts/launch.sh will work.

One ask: I couldn't reproduce the exact German failure on our rig (no comma-decimal locale data installed there), so the mechanism is certain but you're the perfect validator — could you confirm LC_NUMERIC=C bash scripts/launch.sh clears it for you? That nails it down before we merge.

Cool Nice thanks a lot is running now :)

Merged — PR #160 is on master. After a git pull you can drop the LC_NUMERIC=C prefix; plain bash scripts/launch.sh now works regardless of locale. Thanks for confirming on the German-locale machine — that was the validation we couldn't reproduce on our rig, so it genuinely closed this out. 🎉

nice thanks
