Dear Leo,

i manage to install Ubuntu Noble 24.04,  by using ISO image of today 
9-3-2024.

The workaround to avoid the below error is to rename the file :

ubuntu.sources    into  ubuntu.sources.old

into  directory "/etc/apt/sources.list.d/

then logout and login and i made installation  again and it worked !!!.

Now  i am using , the new istallation.

Rgds

Santino

    Title:
       /usr/lib/grub/grub-multi-install fails on noble-daily

    Status in subiquity:
       Invalid
    Status in grub2 package in Ubuntu:
       Fix Released

    Bug description:
       I am using subiquity to install the current noble daily ISO (server).

       Subiquity failed the step called "installing grub to target devices"
       and the logs show that /usr/lib/grub/grub-multi-install failed
       silently with exit status 10.

       When running the script with `set -x`, we see the following, which
       seem to indicate that the absence of a debconf selection variable is
       causing trouble:

       + set -e
       + . /usr/share/debconf/confmodule
       ++ '[' '!' '' ']'
       ++ PERL_DL_NONLAZY=1
       ++ export PERL_DL_NONLAZY
       ++ '[' '' ']'
       ++ exec /usr/share/debconf/frontend /usr/lib/grub/grub-multi-install
       + set -e
       + . /usr/share/debconf/confmodule
       ++ '[' '!' 1 ']'
       ++ '[' -z '' ']'
       ++ exec
       ++ '[' '' ']'
       ++ exec
       ++ DEBCONF_REDIR=1
       ++ export DEBCONF_REDIR
       ++ dpkg-query --control-path grub-common templates
       + db_x_loadtemplatefile /var/lib/dpkg/info/grub-common.templates
    grub-common
       + _db_cmd 'X_LOADTEMPLATEFILE
    /var/lib/dpkg/info/grub-common.templates' grub-common
       + _db_internal_IFS='
       '
       + IFS=' '
       + printf '%s\n' 'X_LOADTEMPLATEFILE
    /var/lib/dpkg/info/grub-common.templates grub-common'
       + IFS='

       + read -r _db_internal_line
       + IFS='
       '
       + RET=0
       + case ${_db_internal_line%%[     ]*} in
       + return 0
       + cached_available_ids=
       + db_get grub-efi/cloud_style_installation
       + _db_cmd 'GET grub-efi/cloud_style_installation'
       + _db_internal_IFS='
       '
       + IFS=' '
       + printf '%s\n' 'GET grub-efi/cloud_style_installation'
       + IFS='

       + read -r _db_internal_line
       + IFS='

       + RET='10 grub-efi/cloud_style_installation doesn'\''t exist'
       + case ${_db_internal_line%%[     ]*} in
       + return 10
