ADDITIONAL INFORMATION
Comment 1 benjamin 2022-07-23 20:33:35 UTC
the problem stems from a kernel update on a full disk encryption exceding 100mb for the initial ramdisk.
i suspect every system with full disk encryption will be affected by this bug.
i could work arround it by setting modules=dep in the initramdisk tools config file and generate new init ramdisks.
it sounds way easier than it is. it costed me a week to get back into my system.
this bug is critical and should be fixed asap

Thank you for your bug report! 
However this bug report was created/provided previous to 01/01/2023 and also has not received any updates since  before 01/01/2025. 
Unfortunately KDE neon no longer provides updates for anything older than noble 24.04 based edition's.
Please upgrade to KDE neon noble and if you can reproduce the issue after upgrading to an active version, feel free to re-open this bug report.
Thanks for understanding!
