Patch for /usr/share/initramfs-tools/scripts/init-bottom/dropbear on
Ubuntu 22.04-LTS
This feels like the better place, as it respects dropbear's original
semantic for IFDOWN on systems which run netplan. Needs to be followed
by update-initramfs -u -k 'all'
/root/dropbear-orig
Confirming the clevis issue.

The same problem occurs when the hdd is automatically decrypted with
clevis and a tang server. The script /usr/share/initramfs-

I can confirm the workaround by boxeus works on Ubuntu 20.04 LTS. To
improve on that, the lines can be added to the /etc/dropbear-
initramfs/config config file instead to avoid upgrade issues. It is
loaded towards the end of /usr/share/initramfs-tools/scripts/init-
bottom/dropbear anyway.
Which version of Mint (or which upstream Ubuntu it is based on?) I
wonder if there is a way to get those rows into the configs rather than
editing packaged files?

The easiest way to fix this on linux mint for me was to edit:
/usr/share/initramfs-tools/scripts/init-bottom/dropbear
add these two lines to the end of file:
rm /run/net-*.conf
rm /run/netplan/*.yaml
save and run:
update-initramfs -u

Title:
DROPBEAR_IFDOWN=* takes interface down
Digging even further back, it turns out that IFDOWN is in itself a
workaround for an equal issue dating back to ~2012. As such, the core of
the issue lies with how initramfs network setup overrides netplan.
Adding that package.
Given the very limited setup /etc/initramfs-tools/initramfs.conf
