Research direction

Start by reproducing the failure in the termux/termux-docker image with pkg upgrade, pkg install gh, and gh auth login; also inspect the referenced Git LFS build.sh section. Trace why certificate authorities are unavailable in termux-docker, then verify that GitHub CLI and Git LFS work without SSH-only access or GIT_SSL_NO_VERIFY=1.

Written by the indexing model from the issue text.

Description

This issue is to track the termux-docker variant of tls: failed to verify certificate: x509: certificate signed by unknown authority.

Every type of termux-docker has this issue, and my recent heavy changes did not introduce it. Unfortunately, I didn't fix it because I don't know how to.

Sometimes, GNU/Linux or normal Android can have tls: failed to verify certificate: x509: certificate signed by unknown authority also, but when they do, it's thought to be due to a different root cause, because generic solutions for this error from GNU/Linux and normal Android don't seem to help.

Some known affected programs:

GitHub CLI
Git LFS

Most programs are not known to be affected.

Reproduction steps
GitHub CLI
docker run -it termux/termux-docker:x86_64 # any architecture
pkg upgrade
pkg install gh
gh auth login
Git LFS
