After upgrade from 140.12.0esr all (open)pgp keys are gone. I cannot
encrypt any email.
The dialog 'Tools->OpenPGP Key Manager' stays empty. Importing Keys from
the thunderbird version before ist not possible. It throws the Error:

It may be the cause, because the RNP library was removed with 153.4.0
esr release in case of security issues.
What I tested, because I thought it could be a migration error:
1. Downloaded the 153.3.1 esr as tar.xz from the official thunderbird
archive
profile. Result: the keys there at 'OpenPGP Key Manager'.

3. Upgraded the official thunderbird version up to 153.5.1 esr and
started it again. Result: the keys there at 'OpenPGP Key Manager'.

4. After that I startet the debian thunderbird 153.5.1 esr again.
Result: the keys are gone at 'OpenPGP Key Manager'. No keys available. I
cannot read my encrypted mails and I cannot import keys.

Looks like it is not a migration problem.


Is something missing in the debian thunderbird 153.5.1esr
(stable-security) version?


I am on Debian 13 Trixie (stable): Linux fsx13g4 6.12.113+deb13-amd64 #1
SMP PREEMPT_DYNAMIC Debian 6.12.113-1 (2026-10-15) x86_64 GNU/Linux

Help is needed because I am using a mail server with pgp encrypted mails.

Thank you all.

Hello,

that issue was reported already in

#1152139  https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1152139
and
#1152248  https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1152248

I merge the bug report into the other ones.

No keys are deleted or "gone", there are just not accessible due the to
old used librnp0 library from the archive. A fix i on the way.
