I2p not available in bookworm

Problem Description
plinth/apps/i2p Installation: i2p page says, “This application is not available in your distribution.”

Are we missing i2p-router package in bookworm? If so, is there a workaround to this while still having the application controlled by FreedomBox (maybe an out-of-process install of i2p-router)?
Instructions for this are at geti2p.net

Steps to Reproduce

  1. Start with frequent-feature update/advanced apps and features enabled Bookworm FreedomBox having i2p installed via plinth (since buster)
  2. do sudo apt install -t bookworm-backports freedombox to correct automatic updates to freedombox
  3. do rerun setup on i2p from plinth
  4. do Uninstall on i2p from plinth
  5. intending to install i2p anew I now see the, “This application is not currently available in your distribution.” message. Surprise! :disappointed:

Expected Results
I expected the application to be available for installation after uninstalling the application. Sadly, it is not.

Actual results
The plinth/apps/i2p page tells me:

This application is currently not available in your distribution.



  • FreedomBox version: You are running Debian GNU/Linux 12 (bookworm) and FreedomBox version 23.16. FreedomBox is up to date.
  • Hardware: intel Atom PC uname -a: Linux fbhostname 6.1.0-11-amd64 #1 SMP PREEMPT_DYNAMIC Debian 6.1.38-4 (2023-08-08) x86_64 GNU/Linux
  • How did you install FreedomBox?:
    • netinst debian buster
    • DEBIAN_FRONTEND=noninteractive apt install freedombox -y
    • unattended upgrade to bullseye
    • upgrade to bookworm

Additional Troubleshooting
The installation issue for i2pd does not appear to be an unresolved dependency. i2p-router package doesn’t seem to be in bookworm, however.

apt search i2p-router gives:

Sorting… Done
Full Text Search… Done

apt search i2p gives:

i2pd/stable 2.45.1-1 amd64
Full-featured C++ implementation of I2P client

aptitude shows dependency issues with i2pd installation. Bookworm distribution packages for libboost-filesystem, libboost-program-options, and libminiupnpc all appear to satisfy the install dependencies for i2pd.

There’s an open Debian bug on i2p for a security issue: “Attackers can de-anonymize i2p hidden services with a message replay attack” that probably led to removal from testing before testing became bookworm.


Thanks for checking bugs. It looks like a FreedomBox users hosting eepsites are at risk. It is not clear to me from reading these whether http/https proxies or i2psnark are at risk. http(s) and i2psnark are not eepsites.

CVE-2023-36325: Attackers can de-anonymize i2p hidden services with a message replay attack synopsis:

If you host eepsites with Java i2p and are running older than i2p 2.3.0, update it as soon as possible.

Users of i2pd are not affected.
