And, the second error when user connect to the SSH server.

Tell me if you need more debug logs. Thanks

Looks like related with #13684

Looks like related with #13684

@lunny no, it's constantly pouring in the logs (I use helm chart). Not just when a user is actively using the webui. Maybe a k8s probe call.

But why the panic aren't logged properly?

[zeripath]

Update to 1.13.1

[jeanlucmongrain]

Update to 1.13.1

that fixed it... but that logs:

Unable to negotiate with 10.42.0.116 port 49242: no matching key exchange method found. Their offer: diffie-hellman-group14-sha1,diffie-hellman-group-exchange-sha1,diffie-hellman-group1-sha1 [preauth]

Could not load host certificate "/data/ssh/ssh_host_dsa_cert": No such file or directory

is still there in a loop

[zeripath]

Those can be ignored except for that you say they are in a loop indicating that it is constantly restarting which is a configuration issue that you will have to look at.

If you really don't want to see them edit your sshd_config to fix them (either the template or /etc/sshd_config). They will be caused by the:

gitea/docker/root/etc/templates/sshd_config

Line 11 in ac97ea5

HostCertificate /data/ssh/ssh_host_ed25519_cert

gitea/docker/root/etc/templates/sshd_config

Line 13 in ac97ea5

HostCertificate /data/ssh/ssh_host_rsa_cert

gitea/docker/root/etc/templates/sshd_config

Line 15 in ac97ea5

HostCertificate /data/ssh/ssh_host_ecdsa_cert

gitea/docker/root/etc/templates/sshd_config

Line 17 in ac97ea5

HostCertificate /data/ssh/ssh_host_dsa_cert

Which can be removed if you never intend to use certificates.

[mschoettle]

Wouldn't the other way around be better? By default it is disabled and if someone wants to use certs they can customize the config. The comment in PR #13143 "Afaik, adding these lines does nothing unless the file(s) are present" is not true since it does cause errors and spams the log.

How can I edit the template to remove those lines? Is it possible such that an upgrade to Gitea will keep these settings?
