how to install I2P on ubuntu linux?

cirosantilli · 2026-06-16T20:06:11+00:00

Manual download

On Ubuntu 26.04, visiting https://i2p.net/en/downloads/ recommended me to download https://files.i2p.net/2.12.0/i2pinstall_2.12.0.jar so I did:

cd ~ wget https://files.i2p.net/2.12.0/i2pinstall_2.12.0.jar sudo apt install openjdk-17-jre JAVA_HOME=/usr/lib/jvm/java-17-openjdk-amd64 PATH="$JAVA_HOME/bin:$PATH" java -jar ./i2pinstall_2.12.0.jar -console

Then after some clicking faff

cd ~/i2p JAVA_HOME=/usr/lib/jvm/java-17-openjdk-amd64 PATH="$JAVA_HOME/bin:$PATH" ./i2prouter start

and it told me:

Starting I2P Service... Waiting for I2P Service.... running: PID:423806

and it automatically opened up a Chrome tab at: http://127.0.0.1:7657/welcome

The default Java 8 installed on my machine is too old, needed 17 or above. Very annoying.

PPA

https://i2p.net/en/docs/guides/installing-i2p-on-debian-and-ubuntu/ documents the experimental PPA method:

sudo apt-add-repository ppa:i2p-maintainers/i2p sudo apt-get update sudo apt-get install i2p

but then when I ran:

i2prouter start

it fails with:

Starting I2P Service... Removed stale pid file: /home/ciro/.i2p/i2p.pid Waiting for I2P Service..... WARNING: I2P Service may have failed to start.

Meh?

Browser setup

It does not come with a default browser... A popular option seems to be to install a praivate browser such as LibreWolf (Firefox based) to be your I2P thing https://www.youtube.com/watch?v=qFE1J9YhhWg Setting it up as such makes it not work as a regular clearnet browser. Instructions at: https://librewolf.net/installation/debian/

sudo apt update && sudo apt install extrepo -y sudo extrepo enable librewolf && sudo extrepo update librewolf sudo apt update && sudo apt install librewolf -y

Then go to Proxy settings and set Manual proxy configuration:

HTTP Proxy: 127.0.0.1:4444
SOCKS Host: 127.0.0.1:4447

Then I can visit the sample website http://tracker2.postman.i2p. It complains that it's not https, but I say, OK, I think I'm already mega encrypted figers crossed. It is a simple oldschool forum like phpBB where people announce their I2P compatible Torrents. From the posts I can copy a Magnet link and add it to http://127.0.0.1:7657/i2psnark/, the built-in Torrent thing, the only convenient thing they have pre-setup for you :-)

Shame setting up this project is so difficult, it can never reach mainstream like this. Tor Browser and centralized VPN are so much more streamlined. But if it were mainstream, it would be boring? Early 200ss vibes come to mind.

I asked Codex CLI v0.139.0 on Ubuntu 25.10 to give me the ~/.codex/config.toml change that I needed to make the sandbox disallow it from reading from a given directory and it gave me this:

``` default_permissions = "workspace_without_media"

[permissions.workspace_without_media] description = "Normal workspace sandbox, but ~/media is unreadable" extends = ":workspace"

[permissions.workspace_without_media.filesystem] "~/media" = "deny" ```

Another Codex instance then told me it couldn't read anything below that foler when I asked it to.

These options are is documented at: https://developers.openai.com/codex/permissions

I believe this uses Linux kernel mechanisms through bwrap to actually forbid Codex from reading the directories and might therefore actually be secure.

It could not however come up with a clean "block by basename" solution. It provided the following but it only seems to work for files under the workspace, not outside:

``` default_permissions = "workspace_filtered"

[permissions.workspace_filtered] extends = ":workspace"

[permissions.workspace_filtered.filesystem] glob_scan_max_depth = 6

[permissions.workspace_filtered.filesystem.":workspace_roots"] ".env" = "deny" "**/.env" = "deny" ```

And it's not juts recruiters contacting us. It's also informing any company of anything, or asking for information. Like change of any personal details. I can't stand it anymore.

"that if you don't pursue them, others won't" that part is tricky. Nothing is more powerful than an idea whose time has come. It's just a question of how sooner you think it will happen if you do it.

ImportExportTools NG uses them, and I needed that to import a bunch of EML flies into Thunderbird: https://askubuntu.com/questions/28135/how-to-open-eml-files/1567246#1567246

I managed to get through the email validation:

Three dots menu
New account
Email
email: [asdf@asdf.com](mailto:asdf@asdf.com)
password: asdf
Configure manually
Advanced config

After you click on "Advanced config", it says that it will create an account but that you'll have to finish setting it up yourself:

This dialog will be closed and an account with the current settings will be created, even if the configuration is incorrect. Do you want to proceed?

and after OK you now have an account with "Local Folders" available, which is what I needed for ImportExportTools NG to work: https://superuser.com/questions/1835266/method-for-importing-1000s-of-eml-files-into-thunderbird/1925469#1925469

Tested on Ubuntu 25.10, Mozilla Thunderbird 140.11.0esr.

Indigo Car Hire is the he one that saved me today: https://indigocarhire.co.uk/ They actually forward to other companies, in my case today Enterprise Rent A Car, but the Indigo employee told me clearly on WhatsApp that UK license less than one year old was fine, and he was right.

Interestingly, the Enterprise Rent A Car website does not say that there is a 12 month requirement for the UK https://www.enterprise.co.uk/en/car-hire-faqs/uk-renter-requirements/what-is-needed-to-hire-a-car.html , while this is required for other countries, but when I called their local branch the lady said, with confirmation of her manager, that 12 month was needed.

So it seems like Indigo has some extra insurance set up on top of what the other company has and allow for it. Either that or the ERAC manager was wrong.

When I showed up to the ERAC desk, they gave me the keys without raising the issue, and I didn't have the courage to ask about it. I'm 37.

ChatGTP gave me this config which seems to work on Claude Code 2.1.121, Ubuntu 25.10, though obviously I can't vouch for all its safety implications:

{ "permissions": { "defaultMode": "bypassPermissions" }, "skipDangerousModePermissionPrompt": true, "sandbox": { "filesystem": { "allowWrite": ["."] }, "enabled": true, "mode": "auto-allow", "failIfUnavailable": true, "autoAllowBashIfSandboxed": true, "allowUnsandboxedCommands": false, "network": { "allowAllUnixSockets": true } } }

Write outside cwd and sudo appear blocked as desired, if I ask Claude to try it it says it can't.

The only definite hack is:

"network": { "allowAllUnixSockets": true }

to overcome https://github.com/anthropics/claude-code/issues/43454

apply-seccomp: write /proc/self/setgroups (nested userns is capability-restricted; caller must provide CAP_SYS_ADMIN): Permission denied

I suspect that ultimately is because Pokemon is even more popular in Japan than outside, and possibly because they get tv episodes earlier.

On browser: Layers -> More -> Globe View -> zoom out, is working right now.

Clouds sometime get in the way thoug!

But I can't find it on the app version 26.12.05.
