[sscjjo]

我也是一样，不知道什么问题

[BulldozerPete]

I don’t understand.

Hi! @BulldozerPete did you manage to find a solution? i have the same problem. I keep getting internal error when i try to generate a new ssl certificate, or when i try to renew the old one,

[GGontijo]

Same here... Has anyone found a solution? I’m not using the challenge method though.

[BulldozerPete]

No solution yet.

[marlowleon]

@BulldozerPete any work arounds? coming close to a mass of sites expiring

Hi @BulldozerPete @marlowleon @GGontijo @Petrut-u
Had the same / similar issue.

Even if you run the correct image, pull it again with the docker pull command: docker pull jc21/nginx-proxy-manager:latest.

I was already running that image but somehow run in to the error, after repulling the image everything worked as expected.

Let me know if it also fixed the issue for you :)

[AlfaJackal]

Same issue here...

[BulldozerPete]

Fix doesn’t work

The issue appears to be that the certbot-dns-multi package on PyPI is not available for ARM architecture (PyPI files for that package). I do not know if it ever was or if this is only the case for the latest version of this package, but at least for the couple of older versions I checked, I never found an ARM package. So the package has to be build during the installation. This fails as no Go compiler is available in the Docker container.

As a workaround you could build a new Docker container based on the official one containing the Go compiler and other build requisites:
Unfortunately the Go compiler from the Debian packages is too old (also the one in bookworm-backports is too old according to some issue comments in alexzorin/certbot-dns-multi), so one has to download a version from https://go.dev/dl/, i.e. https://go.dev/dl/go1.24.5.linux-arm64.tar.gz. This archive should be next to a Dockerfile looking like
