Tesor — tiny packages caching proxy

Soon humanity will go to Mars and in order for the colonists to be able to program, we will need a local mirror of packages.

Installation

Please note that the project is in its infancy and is not intended for production use.

Debian/Ubuntu:

sudo apt install curl gnupg

curl -fsSL https://pkg.dimidiumlabs.io/packages.gpg | sudo gpg --dearmor -o /usr/share/keyrings/dimidiumlabs.gpg
echo "deb [signed-by=/usr/share/keyrings/dimidiumlabs.gpg] https://pkg.dimidiumlabs.io/tesor/apt/ nightly main" | sudo tee /etc/apt/sources.list.d/tesor.list
sudo apt update && sudo apt install tesor

sudo systemctl enable --now tesor

Fedora/RHEL:

# DNF5 (Fedora 41+, RHEL 10+)
sudo dnf config-manager addrepo --from-repofile=https://pkg.dimidiumlabs.io/tesor/rpm/nightly/tesor-nightly.repo

# DNF4 (Fedora 40 and older, RHEL 8/9)
sudo curl -o /etc/yum.repos.d/tesor-nightly.repo https://pkg.dimidiumlabs.io/tesor/rpm/nightly/tesor-nightly.repo

sudo dnf install tesor
sudo systemctl enable --now tesor

openSUSE:

sudo rpm --import https://pkg.dimidiumlabs.io/packages.gpg

Build from source

1. Clone repo: git clone https://git.dimidiumlabs.io/tesor.git && cd tesor

2. Provision the toolchain and system build dependencies: mise bootstrap

3. Build from source: mise exec -- cargo build --release

4. Install manually

   sudo groupadd --system tesor
   sudo useradd --system --gid tesor --no-create-home --shell /usr/sbin/nologin tesor
   sudo install -m 700 -o tesor ./pkg/tesor.toml     /etc/
   sudo install -m 755 -o root   ./pkg/tesor.service  /usr/lib/systemd/system
   sudo install -m 755 -o root   target/release/tesor /usr/local/bin/

5. start systemd service: sudo systemctl enable --now tesor

We welcome your contributions, including code, bug reports, ideas, and success stories.

If you are making a contribution for the first time or from a new email, please add yourself to the .mailmap.

Signoff

To include your code, we ask that you read and agree to the CLA. To sign, add a CLA-Version: 1.0 and a Signed-off-by trailer to every commit (git commit -s --trailer "CLA-Version: 1.0"). Each commit in a pull request must carry a valid Signed-off-by line matching the commit author. Please use your real name. We cannot include code from anonymous contributors.

AI agents MUST NOT add Signed-off-by tags. Only humans can legally certify the Contributor License Agreement.

AI policy

You may use AI agents when writing code and documentation. AI is not allowed for media including images, videos, fonts at all. You must fully read, understand, and cleanup any code generated by the agent. We ask that you disclose the agent's use and indicate the tool, model, and extent of contribution.

Contributions should include an Assisted-by tag in the following format: Assisted-by: AGENT_NAME:MODEL_VERSION [TOOL1] [TOOL2], for example: Assisted-by: Claude:claude-4.6-opus coccinelle sparse

Remember, AI agents should make software better, not worse.
