From: Herpiko Dwi Aguno Date: Thu, 10 Sep 2026 00:00:00 +0700 Subject: fix: use the live medium as the only apt source during install Offline installs failed at bootloader-config: apt resolved grub-pc from the live-build network mirror that unpackfs copies into the target as /etc/apt/sources.list, rather than from the medium repo that sources-media registers under sources.list.d. APT parses sources.list first and does not fall back to another source when the chosen one cannot be fetched, so with no network the install aborted even though grub-pc and grub-pc-bin are both present on the ISO. --- helpers/calamares-sources-media | 8 ++++++++ 1 file changed, 8 insertions(+) diff --git a/helpers/calamares-sources-media b/helpers/calamares-sources-media index f0291a5..467dea1 100755 --- a/helpers/calamares-sources-media +++ b/helpers/calamares-sources-media @@ -22,6 +22,14 @@ fi # Remove the base sources, we will configure sources in a later phase rm -f $CHROOT/etc/apt/sources.list.d/base.list +# unpackfs copies the live-build network mirror into the target as +# /etc/apt/sources.list.
