Package repositories

Installing the deb or rpm package from a file also adds the Astela repository, so the browser updates together with the system. To add the repository first instead:

Debian and Ubuntu

curl -fsSL https://secoolioo.github.io/astela/linux-repo.asc |
  sudo tee /usr/share/keyrings/astela.asc >/dev/null
sudo tee /etc/apt/sources.list.d/astela.sources >/dev/null <<EOF
Types: deb
URIs: https://secoolioo.github.io/astela/apt
Suites: beta
Components: main
Signed-By: /usr/share/keyrings/astela.asc
EOF
sudo apt update && sudo apt install astela

Fedora and RHEL

sudo tee /etc/yum.repos.d/astela.repo >/dev/null <<EOF
[astela]
name=Astela
baseurl=https://secoolioo.github.io/astela/rpm/beta
enabled=1
gpgcheck=1
repo_gpgcheck=1
gpgkey=https://secoolioo.github.io/astela/linux-repo.asc
EOF
sudo dnf install astela

Until the first stable release, packages are published on the beta channel only. It also receives every stable release.

Verify a download

SHA256SUMS lists every file of a release. It is signed with the package repository key (SHA256SUMS.asc) and with the update key (SHA256SUMS.sig). Each file also has a build provenance attestation from the release workflow.

sha256sum --check --ignore-missing SHA256SUMS
curl -fsSL https://secoolioo.github.io/astela/linux-repo.asc | gpg --import
gpg --verify SHA256SUMS.asc SHA256SUMS
gh attestation verify astela-linux-x86_64.AppImage --repo Secoolioo/astela

Notes

• Windows and macOS ask for confirmation on the first start until the packages are signed with publicly trusted certificates.
• The MSI package is meant for managed deployment and is published for stable releases only.
• The AppImage needs no installation. On Ubuntu 24.04 and later it explains how to enable the browser sandbox on its first start.
