/proc/modules error when trying to install mate with preseed

[kerryhall]

I have been automating dozens of Debian installs for awhile now using a preseed command as follows (or similar):

Code: Select all

d-i preseed/late_command string \
sed -i '/cdrom/d' /target/etc/apt/sources.list;\
echo "kerry ALL=(ALL:ALL) NOPASSWD:ALL" >> /target/etc/sudoers;\
cp /cdrom/playbooks.tar.gz /target/home/kerry;\
tar xzf /target/home/kerry/playbooks.tar.gz -C /target/home/kerry;\
chroot /target mkdir /dev/shm;\
chroot /target mount -t tmpfs none /dev/shm;\
chroot /target mkdir /dev/pts;\
chroot /target mount -t devpts -o gid=4,mode=620 none /dev/pts;\
chroot /target runuser -l kerry -c 'ansible-playbook -i "localhost," -c local /home/kerry/playbooks/base.yaml';\
chroot /target runuser -l kerry -c 'ansible-playbook -i "localhost," -c local /home/kerry/playbooks/desktop-mate.yaml';\
rm /target/home/kerry/playbooks.tar.gz;\
rm -rf /target/home/kerry/playbooks

Running other playbooks as desired. This has worked well for Debian 7, 8, 9, and now trying it with 10.

Unfortunately this was not successful, failing at the installation of mate step. (Just includes a few packages and that's really it)

The installation log is almost a meg so I will not include it here, but I did see the following line:

Code: Select all

Setting up fuse (2.9.9-1) ...\r\nlibkmod: ERROR ../libkmod/libkmod-module.c:1657 kmod_module_new_from_loaded: could not open /proc/modules: No such file or directory

This of course causes the whole package tree to fail installation.

How would I go about working around this?

[p.H]

Looks like /proc is not mounted and is required to be.

[Head_on_a_Stick]

Code: Select all

chroot /target mkdir /dev/shm;\
chroot /target mount -t tmpfs none /dev/shm;\
chroot /target mkdir /dev/pts;\
chroot /target mount -t devpts -o gid=4,mode=620 none /dev/pts;\

Perhaps try this instead:

Code: Select all

for i in proc sys dev{,/pts,/shm} ;\
do mount --bind /$i /target/$i ;\

I had to keep my procedure for shm and pts, but doing the bind mount for proc and sys worked! Thank you!
