Modules for new kernels aren't built because there was an error saying I am not root.

      Code:

After digging a bit, /usr/sbin/dkms never initializes the variable UID

      Code:
grep UID /usr/sbin/dkms
    if ((UID != 0)); then
    ((UID == 0)) && return
        if ((UID != 0)) && [[ $force = true ]]; then


Adding the line below somewhere at top the script fixes it:
      Code:
UID=$(id -u)

Without having dug into it deeper (I don't really like the way dkms works), the situation is a bit weird. While $UID is not a variable mandated by POSIX shells, it is defined by bash and - and /usr/sbin/dkms does explicitly use #!/bin/bash as shebang. At least the 'normal' ways dkms appears to be invoked, is via exec, which in turn should use bash to execute the script (thereby defining $UID), but apparently it isn't executed rather than sourced on your system somehow (which would be the only way to end up with your error condition). Unfortunately I don't really see how this would happen (assuming that /bin/bash is indeed provided by bash, check "/bin/bash --version", which it really should be).

In order to debug this further, it would probably make sense to run "debsums -as" on your system, to check for eventual disk corruption and/ or modified conffiles (there typically are several under /etc/, so that isn't a problem per se, but it might hint at potential problems). Furthermore you apparently still have /etc/kernel-img.conf on your system, which isn't supposed to be present anymore (while it shouldn't exactly break havoc, it has the potential to do so - it is safe to remove it).

Ok, this is the bash command
      Code:
 /bin/bash --version ; apt-cache policy bash
GNU bash, version 4.4.11(1)-release (x86_64-pc-linux-gnu)

        500 http://httpredir.debian.org/debian sid/main amd64 Packages
        100 /var/lib/dpkg/status


and this is kernel-img.conf
      Code:
cat /etc/kernel-img.conf
# Kernel Image management overrides
# See kernel-img.conf(5) for details
do_symlinks = Yes
do_bootloader = no
do_initrd = Yes
relative_links = Yes

I'll run debsums -as, too

Thanks slh,
Lat

I decided to dist-upgrade before running debsums -as. During that I saw "/usr/sbin/dkms: line 40: UID: readonly variable" which is where I put my work around. Could it be that it got fixed?

      Code:
...
Building initial module for 4.9.0-0.slh.1-aptosid-amd64
/usr/sbin/dkms: line 40: UID: readonly variable
Done.
/usr/sbin/dkms: line 40: UID: readonly variable
/usr/sbin/dkms: line 40: UID: readonly variable
..

sed -n '40 p' < /usr/sbin/dkms
UID=$(id -u)

As mentioned, /etc/kernel-img.conf should be removed and doesn't contain any required/ useful content (anymore).

"UID: readonly variable" does make sense, if the script is executed under bash (given that bash itself sets this variable and overriding it would be problematic under normal circumstances).
