Hi,
I currently maintain two packages that use Debconf to decide whether to
conduct some additional cleanup on uninstall, osk-sdl[0] and unl0kr[1].
Osk-sdl is deprecated upstream, so I'm trying to transition users of it
to Unl0kr as part of the Trixie upgrade.
This upgrade process is working fine, with one exception, Unl0kr is
unable to read osk-sdl's Debconf entries and thus leaves the system
configured for it on uninstall, breaking disk encryption password entry
and soft-bricking the user's device.
The code I'm using is at
https://salsa.debian.org/DebianOnMobile-team/unl0kr/-/merge_requests/4/diffs#374a42abd88ea86fce84dcb1830e3f8662e5c597_14_14,
it basically attempts to access the osk-sdl Debconf entry and perform
the cleanup. Reading this entry from `debconf-show unl0kr` works fine
but not in the package prerm script.
What I've tried so far:
* Reading osk-sdl's Debconf from Unl0kr => returns "not set".
* Reading osk-sdl's Debconf from osk-sdl and setting Unl0kr's => Unl0kr
doesn't see it's config as set.
* Cleaning up osk-sdl's config on removal of osk-sdl => This would work,
but I want users to be able to manually remove osk-sdl and retain a
working system. The package will eventually be removed from Debian.
I'm hoping there's something simple I'm missing, but any pointers would
be highly appreciated.
Thanks,
Jarrah.
