Debians,

From a preseed file I need to download and execute as the last command

Can someone confirm when 'preseed/run' is executed?

In other words, what is the best way to download and execute a script at
the end of the install process.

Any help is appreciated.

Not exactly answering your question, but the installation-guide
has a chapter about this, see https://d-i.debian.org/manual/en.amd64/apbs05.html

I guess, "preseed/late_command is what you want...

Actually I was more hoping for an equivalent of 'preseed/run' to the 'preseed/late_command'.
The late_command will not per default download the *.sh file.

Thanks alot for your answer.

Qoute from that page
#d-i preseed/late_command string apt-install zsh; in-target chsh -s /bin/zsh

This is untested:

d-i preseed/late_command string in-target wget -O /target/myscript http://server.local/install_script ; in-target bash /myscript


Consider to share with the mailinglist (and the mailinglist archive)
what worked for you.

Actually I was more hoping for an equivalent of 'preseed/run' to the
'preseed/late_command'.
The late_command will not per default download the *.sh file.

The preseed/run part is documented in chapter B.5.3 "Chainloading of preconfiguration files":
https://d-i.debian.org/manual/en.amd64/apbs05.html

So I guess this not a functionality to be executed at the end of installation, it only makes sense somewhere at the beginning.

Thank you for this,

I guess you are refering to:

"
# Most flexibly of all, this downloads a program and runs it. The program
# can use commands such as debconf-set to manipulate the debconf database.
# More than one script can be listed, separated by spaces.
# Note that if the filenames are relative, they are taken from the same
# directory as the preconfiguration file that runs them.
#d-i preseed/run string foo.sh"

In the description text, to me at least, it is not clear at what stage
this command is executed!!! :)
Having played a bit more, I can confirm that this command is not
executed at the end of the installation process.

While I was looking to understand what was going on, I came across (1)
and this is where Ubuntu differs from Debian:

"on a web server. In this example, if the preseed file sets preseed/run
to /scripts/late_command.sh then the file will be fetched from http://autoserver.example.com/d-i/focal/./scripts/late_command.sh."

I would love to see a rewording of the above text which would clearly
state at what time the command is executed!!! :)

I realy appreciate your help.

That starts with smiling to the "works for me".
Next step is documenting how to reproduce "how it fails for me"
