fatal: failed to set up maintenance schedule

[alexanderilyin]

I'm trying scalar in Dev Containersand getting some errors & fatals:

⬢ [Docker] ❯ scalar register
error: another process is scheduling background maintenance
fatal: failed to set up maintenance schedule
error: another process is scheduling background maintenance
fatal: failed to set up maintenance schedule
error: another process is scheduling background maintenance
fatal: failed to set up maintenance schedule
warning: could not turn on maintenance

Here is distro in the image:

⬢ [Docker] ❯ lsb_release -a
No LSB modules are available.
Distributor ID: Debian
Description:    Debian GNU/Linux 12 (bookworm)
Release:        12
Codename:       bookworm

And this is the image I'm in:

FROM mcr.microsoft.com/devcontainers/typescript-node:1-22-bookworm

Here is VS Code version but it probably does not matter:

⬢ [Docker] ❯ code --version
1.95.3
f1a4fb101478ce6ec82fe9627c43efbf9e98c813
x64

Here is what's running in container:

I also had https://starship.rs/ which been causing some git problems but getting rid of it does not help with error/fatal.

Frequently, containers don't provide access to the systemd scheduler. Likely, we would be able to see that if you reran git maintenance start with GIT_TRACE2_PERF=1 so you could see the child processes that are executed and what their exit codes are.

"systemd" is not running in this container due to its overhead.
Use the "service" command to start services instead. e.g.: 

service --status-all

Thanks for the guidance, my current setup in context is Docker Container in Docker for Desctop, which is WSL2 on Windows 10. My git repo is on the Windows FS so probably I just need to do the new git/scalar thing on host instead of the container. Don't really want to run systemd in container, unless scalar will provide extreme benefits.
