Troubleshooting

Troubleshooting

Installation

  • Error: ../gosrc/src/github.com/gogs/gogs/cmd/cert.go:79: undefined: elliptic.P224
  • Causes: golang package in RHEL/CentOS does not support Elliptic Curve cryptography (because it's patented) and it's specifically removed from CentOS/RHEL.
  • Solution: download and install Go from golang.org/dl.

SSH

SSH connection hangs for 60 seconds

  • Causes: Gogs will request itself (web service) after every SSH push, and your server firewall or ISP does not allow that happen

Incorrect binary path for update hook

  • Causes: you moved Gogs binary to a different location from previous installation.
  • Solution: go to admin dashboard (/admin) and run two tasks:
    • Rewrite '.ssh/authorized_keys' file
    • Resync pre-receive, update and post-receive hooks of all repositories

Push succeeds, but the dashboard timeline doesn't update

Causes

When using git over SSH, Gogs relies on the hook scripts to update the timeline and repository display. Unfortunately, there are many different ways to disable the execution of these scripts.

This happens more often when you store repositories on a mounted device.

Solutions
  • Ensure that the mount point containing the repositories is not set as noexec by issuing the mount command. If necessary, add the exec option to the mount point in /etc/fstab.
  • For vfat (and possibly cifs) mounts, ensure that the uid, gid, and fmask options permit either the Gogs user or a group to which it belongs to execute files on the mount.
  • For network-mounted shares, ensure that your server (NFS or Samba) isn't set to disallow execution on the remote filesystem (refer to the respective documentation for how to accomplish this).

Git

Public key conflict

  • Error:
    • fatal: 'XX/XX.git' does not appear to be a git repository
    • Pushed commits but still shows as a bare repository
  • Causes: there are duplicated SSH keys in ~/.ssh/authorized_keys file, possibly you are/were using GitLab for same system user.
  • Solution: delete the old one and keep the one that was added by Gogs only.

Cannot call 'git' command by Gogs

  • Error: repo.NewRepoContext(fail to set git user.email):
  • Causes: it happens when Windows users install Git Bash without enabling the cmd option
  • Solution: reinstall and enable cmd option.

Cache

  • Error: cache: unknown adaptername "memcache" (forgotten import?)
  • Causes: To prevent unnecessary import of package, we use build tags to specify when needed
  • Solution:
    • Download: go get -tags memcache github.com/gogs/gogs
    • Build: go build -tags memcache
    • Same steps for redis when you want it to be the cache adapter.

Database

Incorrect MySQL storage engine

  • Error: Error 1071: Specified key was too long; max key length is 1000 bytes

  • Causes: it is caused by MyISAM.

  • Solution: Once you import the config/mysql.sql then login into mysql and run:

     use gogs;
 set global storage_engine=INNODB;

After that, go to http://localhost:3000/install and everything works fine(thanks @linc01n).

Outdated MySQL password setting

  • Error: Database setting is not correct: This server only supports the insecure old password authentication. If you still want to use it, please add 'allowOldPasswords=1' to your DSN. See also https://github.com/go-sql-driver/mysql/wiki/old_passwords
  • Causes: only updated the password for @localhost -- there was a second entry in the user table where @% still had the old password.
  • Solution: GitHub comments

Connect to wrong SQLite3 database

  • Error: Push to repository shows owner is not registered or user table does not exist.
  • Causes: You might start Gogs as service and it is using different SQLite3 file that you expect.
  • Solution: Use absolute path to config SQLite3 database path.

Mailer

Windows

  • Error:
2014/09/18 15:04:40 [repo.go:115 CreatePost()] [E] CreatePost: initRepository: initRepository(git clone): cygwin warning:
MS-DOS style path detected: C:\Users\user\gogs-repositories\unos\test3.git/.git
Preferred POSIX equivalent is: /cygdrive/c/Users/user/gogs-repositories/unos/test3.git/.git
CYGWIN environment variable option "nodosfilewarning" turns off this warning.
Consult the user's guide for more details about POSIX paths:
http://cygwin.com/cygwin-ug-net/using.html#using-pathnames
Cloning into 'C:\Users\user\AppData\Local\Temp\484264900'...
fatal: '/cygdrive/d/svnroot/research/gogs/C:\Users\user\gogs-repositories\unos\test3.git' does not appear to be a git repository
fatal: Could not read from remote repository.
  • Causes: you installed the another shell in system, and has different path style.
  • Solution: please try to start Gogs through default CMD.
  • Error: Resource interpreted as Stylesheet but transferred with MIME type application/x-css
  • Causes: wrong value in the Windows registry
  • Solution: Find .css in HKEY_CLASSES_ROOT in registry and change its Content Type to text/css.

Other

  • Error: extremely slow page response but time show on the bottom looks normal(under 100ms)
  • Causes:
    • (1) it may be caused by Nginx try to resolve IPv4 address as IPv6
    • (2) if you allow for avatar lookup with Gravatar without a valid email address
  • Solution:
    • (1) use explicit hostname 127.0.0.1 instead of localhost when you run the initial http://gogs-server:3000/install setup
    • (2) either use a valid Gravatar email address for the created administrator account or uncheck the avatar lookup in the initial http://gogs-server:3000/install setup
  • Error: Error 1062: Duplicate entry 'Unknown-Mac' for key 'UQE_public_key_name'
  • Causes: it is led by legacy code, public_key table used to have UQE_public_key_name unique rule for SSH key name in very early version.
  • Solution: you can delete that unique rule manually to fix this problem.
  • Error: GLIBC_2.14 not found
  • Solution: try sudo apt-get -t testing install libc6-dev.
  • Error: [Macaron] PANIC: session(start): mkdir data: permission denied
  • Causes: Gogs creates data subdirectory at the same directory where Gogs binary is located.
  • Solution: make sure Gogs has permission to create subdirectory at that directory.
  • Error: ! [remote rejected] master -> master (hook declined)
  • Causes: Git fails to execute the update script for some reason.
  • Solution: make sure you have the bash shell available in your system, all the hook scripts needs it.
