The rebase froze, the terminal hung, and seconds stretched into minutes. You hit Ctrl+C, but the process refused to die. This is the Git rebase Linux terminal bug that has been frustrating developers across distributions.
A Git rebase should run cleanly, applying commits and stopping only for conflicts. On some Linux systems, however, rebasing can lock up without warning. The bug often shows up when rebasing large branches or working with repos on network-mounted filesystems. Processes remain in an uninterruptible state, leaving you with a stalled terminal and a dirty index.
Root causes vary. In many cases, the issue involves how Git interacts with the terminal’s stdin/stdout under certain shell configurations. Some users report that their rebase hangs when Git tries to prompt for input after extended operations. This can happen in interactive rebases if the terminal environment variables are mis-set or when the pseudo-terminal fails to pass signals correctly.
If you encounter this bug, first try rebasing with --no-interactive or --committer-date-is-author-date to reduce prompt usage. Running git rebase with GIT_TRACE=1 can help you see which stage triggers the hang. In some shells, switching from bash to zsh or running Git under script can bypass the problem. Another workaround is to avoid the terminal completely for the rebase step, using a GUI or a CI pipeline.
Updating to the latest Git release can resolve known cases, since some patch notes explicitly mention fixes for Linux terminal I/O bugs. Check your distro’s package version — many older defaults still ship with problematic builds. Compiling Git from source ensures you have the newest commit handling logic.
For teams working in fast-moving environments, this bug is more than an annoyance. It disrupts rebases, blocks merges, and can waste hours waiting for processes that never finish. Automating rebases or isolating them in clean, containerized shells minimizes exposure.
