46 Install the sandbox dependencies, then run the installer. The sandbox needs bubblewrap 0.8.0 or later and socat, and installing them takes administrator (root or `sudo`) access; if you don't have it, ask your system administrator to install them, or see [Run Claude Science without administrator access](/docs/claude-science/run-on-remote-linux-server#run-claude-science-without-administrator-access).
46 Install the sandbox dependencies, then run the installer. The sandbox needs bubblewrap 0.8.0 or later and socat, and installing them takes administrator (root or `sudo`) access. Claude Science runs them only from system folders such as `/usr/bin` and `/usr/local/bin` and doesn't search your PATH, so install them with your distribution's package manager, not with conda or Homebrew. If you don't have administrator access, ask your system administrator to install them, or see [Run Claude Science without administrator access](/docs/claude-science/run-on-remote-linux-server#run-claude-science-without-administrator-access).

4949 * Fedora or RHEL: `sudo dnf install -y curl bubblewrap socat`
from line 175
175175* The Windows app reports that it couldn't set up the app window engine: the first launch downloads that engine from `downloads.claude.ai`, and this usually means the app couldn't reach it. Check the internet connection, and on a corporate network ask IT to allow that domain (see [Network requirements](/docs/claude-science/network-requirements)).
176176* On Linux, the installer stops with `The download service may be unreachable, or not yet available in your region`: the installer couldn't get the latest version from `storage.googleapis.com`. Check the internet connection, and on a corporate network ask IT to allow that domain (see [Network requirements](/docs/claude-science/network-requirements#app-connections)). Claude Science is available where Anthropic offers claude.ai. See [Supported countries and regions](https://www.anthropic.com/supported-countries).
177177* On Linux, the shell reports `command not found` for `claude-science`: `~/.local/bin` isn't on your PATH. Add the PATH line that the installer printed to your shell profile, then open a new terminal.
178* On Linux, `claude-science serve` stops with `Sandbox unavailable: bwrap not found on PATH`: bubblewrap isn't installed, or isn't on your PATH. Install bubblewrap and socat with the command for your distribution in the Linux tab of [Install](#install).
179* On Linux, `claude-science serve` stops with `Sandbox unavailable: bwrap too old`: the installed bubblewrap is older than 0.8.0. Check the version with `bwrap --version`, then upgrade bubblewrap. Ubuntu 24.04's repositories carry a new enough version and Ubuntu 22.04's don't.
178* On Linux, `claude-science serve` stops with a `Sandbox unavailable:` message that says `bwrap not found in` a list of folders, or `bwrap was found on PATH at` a path: bubblewrap isn't installed in a system folder. Claude Science runs bubblewrap and socat only from the system folders that the message lists, such as `/usr/bin` and `/usr/local/bin`. It doesn't search your PATH, so it doesn't use a copy from conda, Homebrew, or a folder in your home directory. Install bubblewrap and socat with the command for your distribution in the Linux tab of [Install](#install).
179* On Linux, `claude-science serve` stops with a `Sandbox unavailable:` message such as `/usr/bin/bwrap is too old`: the bubblewrap it names is older than 0.8.0. Check its version in a terminal with that path, for example `/usr/bin/bwrap --version`, then upgrade bubblewrap. Ubuntu 24.04's repositories carry a new enough version and Ubuntu 22.04's don't.
180180* On Linux, `claude-science serve` stops with `Sandbox unavailable: bwrap cannot create unprivileged user namespaces`: the kernel or an AppArmor profile blocks the sandbox from creating user namespaces. The rest of the message names the settings to check on Ubuntu, Debian, and other distributions, and changing them takes administrator (`sudo`) access.
181* On Linux, an error says `socat is required for Linux sandbox networking but was not found in PATH`: socat isn't installed, or isn't on your PATH. Install socat with the command for your distribution in the Linux tab of [Install](#install).
181* On Linux, `claude-science serve` stops with `Sandbox unavailable: socat is required for Linux sandbox networking`: socat isn't installed in a system folder (Claude Science doesn't search your PATH, so it doesn't use a copy from conda, Homebrew, or a folder in your home directory). Install socat with the command for your distribution in the Linux tab of [Install](#install).
182182* Projects from another computer don't appear: by design, Claude Science keeps your work on the computer where it's installed, so each computer starts with its own projects. Your earlier projects are still on the other computer. See [Use Claude Science on more than one computer](/docs/claude-science/multiple-computers).
183183* Projects you created under another sign-in on this computer don't appear automatically, for example, after you move from a personal plan to your organization's Team plan: your earlier projects are still in that sign-in's folder. Select the **Review** button on the banner at the top of the home screen, or select **Review** next to **Access previously saved Claude Science work on this computer** under **Settings** > **General** > **Account**, to access them. On Team and Enterprise plans, if there's no banner and the setting is grayed out, your admin controls it. See [Access work from another sign-in on your computer](/docs/claude-science/multiple-computers#access-work-from-another-sign-in-on-your-computer).
184184* Sign-in stops at claude.ai: your account is on the Free plan (upgrade required), the redirect couldn't return (use **Paste code instead**), or your Team or Enterprise organization hasn't [enabled Claude Science](/docs/claude-science/enable-claude-science) yet.
