Using netboot to install eLxr, getting and installation failure due to incorrect mirror

[deepak]

I am attempting to use the netboot found here (https://mirror.elxr.dev/elxr/dists/aria/main/installer-amd64/current/images/netboot/index.html) to install eLxr.
Now, the problem is:
When trying to install, after I choose the mirror, the installation fails for me saying that the “installer has failed to download files from the mirror”
I understand that I need to use ‘mirror.elxr.dev’ to download the packages. But where and how do I need to make the changes? Note that I am trying to manually install and not use some automation scripts.

Here is a PXE template we use to install eLxr using netboot. We use the Foreman project to fully automate the network boot. Some of the workarounds may not be necessary.

### Partitioning
# The presently available methods are: "regular", "lvm" and "crypto"
d-i partman-auto/method string regular

# If one of the disks that are going to be automatically partitioned
# contains an old LVM configuration, the user will normally receive a
# warning. This can be preseeded away...
d-i partman-lvm/device_remove_lvm boolean true
# The same applies to pre-existing software RAID array:
d-i partman-md/device_remove_md boolean true
# And the same goes for the confirmation to write the lvm partitions.
d-i partman-lvm/confirm boolean true
d-i partman-lvm/confirm_nooverwrite boolean true

# You can choose one of the three predefined partitioning recipes:
# - atomic: all files in one partition
# - home:   separate /home partition
# - multi:  separate /home, /var, and /tmp partitions (/usr was removed in jessie)
d-i partman-auto/choose_recipe select atomic

# If you just want to change the default filesystem to something
# else, you can do that without providing a full recipe.

# This makes partman automatically partition without confirmation, provided
# that you told it what to do using one of the methods above.
