IOHK will launch Daedalus for Linux with the next major Daedalus release (0.12.0 with Cardano 2.0.0). We appreciate the community feedback following the recent Linux beta release, and have prepared an updated beta release based on the latest version, Daedalus 0.11.2 with Cardano 1.3.2. Previous beta releases are no longer compatible with mainnet. See this announcement for more context.

This beta test is aimed at Linux users who are comfortable running a script in a terminal.

Disclaimer

This is beta software we are releasing for public testing. If you test this build with Ada we would like to ask:

Use small amounts of Ada Confirm the 12-word Daedalus wallet recovery phrase restores your wallet in a supported Windows or macOS build As always, keep your wallet recovery phrase safe

In supported Windows and macOS builds there is a mechanism for fetching update versions from the blockchain. That feature is disabled in this Linux beta release. Consequently, when the production Linux release is available you won’t be prompted to update to the next version. Instead you will have to install the initial production release manually.

Usage

These steps assume you are comfortable running scripts in a Linux terminal and are logged into a graphical desktop session as a user other than root.

Download the installer: https://ci-output-sink.s3.amazonaws.com/csl-daedalus/daedalus-0.11.2-cardano-sl-1.3.2-mainnet-x86_64-linux-3541.bin Verify the sha256 hash: sha256sum ~/Downloads/daedalus-0.11.2-cardano-sl-1.3.2-mainnet-x86_64-linux-3541.bin Expected: 6056799de02309cdc5be1b64eaefda698adc9e2fdc11b05c64cd51eb8fea50bc Run the installer: bash ~/Downloads/daedalus-0.11.2-cardano-sl-1.3.2-mainnet-x86_64-linux-3541.bin On some Linux distributions this may initially fail and request you to run some commands as root to enable kernel.unprivileged_userns_clone. If sudo is available, running these two commands should work: sudo sysctl -w kernel.unprivileged_userns_clone=1 sudo echo kernel.unprivileged_userns_clone=1 > /etc/sysctl.d/nix-user-chroot.conf After doing that try running the installer again. Start Daedalus using any of these methods: Using the desktop Application menu Run ~/.local/bin/daedalus-mainnet Run daedalus-mainnet (works on Linux distributions that put ~/.local/bin in $PATH) If you have used previous Daedalus development builds, Daedalus may hang during startup in the network connection phase, with the following error appearing in the console log: logException: Could not parse saved checkpoint due to the following error: too few bytes To recover you will need to remove the wallet database (DANGER: you will need to restore the wallet from the 12-word Daedalus wallet recovery phrase afterwards!): rm ~/.local/share/Daedalus/mainnet/Wallet/ -rf

Providing feedback

We would like to hear about your experiences, both good and bad. There are two ways to submit feedback directly to us. Either way, please, include the phrase Linux Beta in the submission form.

Click on the bug icon in Daedalus. This is the best option if you had problems because it allows you to submit your logs. Click on the Support button in the Support Portal in the bottom-right of the screen.

Thank you for taking part in this beta test, we appreciate your help in getting this software ready for general release.
