Module install error

[licaon-kter]

$ sudo ejabberdctl module_install mod_cron
Error: error
Error: not_available

Umm then how?

ejabberd HEAD (processone/ejabberd@be60263), Debian Bullseye, arm64, Erlang (SMP,ASYNC_THREADS) (BEAM) emulator version 13.1.2

Is it listed in modules_available? Do other modules install correctly, or all fail?

$ ejabberdctl module_install mod_cron
Error: error
Error: not_available

$ ejabberdctl modules_available

$ ejabberdctl modules_update_specs

$ ejabberdctl modules_available
mod_cron        Execute scheduled commands
...

$ ejabberdctl module_install mod_cron
Module mod_cron has been installed and started.
It's configured in the file:
  /home/vscode/.ejabberd-modules/mod_cron/conf/mod_cron.yml
Configure the module in that file, or remove it
and configure in your main ejabberd.yml

Ok, indeed I missed those two commands.

Available comes up empty, as expected I guess.

But

$ sudo ejabberdctl modules_update_specs
Error: {repository,"https://github.com/processone/ejabberd-contrib",
                   {error,enoent}}

The default configuration in most cases results in something like this:

$ make relive
...

> ext_mod:modules_dir().
"/home/badlop/.ejabberd-modules"

I try to reproduce the error message you get:

$ sudo mkdir /tmp/onlyroot

$ CONTRIB_MODULES_PATH=/tmp/onlyroot make relive
...

> ext_mod:modules_dir().
"/tmp/onlyroot"

> ext_mod:update().

 {error, eacces}
 {repository,"https://github.com/processone/ejabberd-contrib",
            {error,eacces}}

The error messages mean:

eacces:
Missing search or write permissions for the parent directories of Dir.

enoent:
The directory does not exist.

It seems the problem in your case is that the parent dir doesn't exist. So I try setting a path with a parent that doesn't exist... and ext_mod succeeds in creating the parent one correctly:

$ CONTRIB_MODULES_PATH=/tmp/abcdefg make relive
...

> ext_mod:modules_dir().
"/tmp/abcdefg"

> ext_mod:update().

Some ideas for you to check:

• What's the result of ext_mod:modules_dir() in your case?
• Does ejabberd have write access to that path?
• Can you try setting other values to CONTRIB_MODULES_PATH?

[licaon-kter]

(ejabberd@localhost)1> ext_mod:modules_dir().
"/var/lib/ejabberd/.ejabberd-modules"

I've checked that path before writing

$ sudo -u ejabberd stat /var/lib/ejabberd/
Access: (0750/drwxr-x---)  Uid: ( 1001/ejabberd)   Gid: ( 1001/ejabberd)

Let's create the folder just in case

$ sudo -u ejabberd mkdir /var/lib/ejabberd/.ejabberd-modules
$ sudo -u ejabberd stat /var/lib/ejabberd/.ejabberd-modules
Access: (0755/drwxr-xr-x)  Uid: ( 1001/ejabberd)   Gid: ( 1001/ejabberd)

Progress, error changed a bit

$ sudo -u ejabberd ejabberdctl modules_update_specs
Error: {repository,"https://github.com/processone/ejabberd-contrib",
                   {error,erofs}}

erofs - Read-only file system

I couldn't reproduce that exact error, I guess I didn't yet reproduce your exact case

(ejabberd@localhost)3> file:make_dir("/tmp/asd").
ok
(ejabberd@localhost)4> file:make_dir("/asd").    
{error,eacces}
(ejabberd@localhost)5> file:make_dir("/bin/asd").
{error,eacces}
(ejabberd@localhost)8> file:make_dir("/bin/").   
{error,eexist}

Anyway, can you try setting other values to CONTRIB_MODULES_PATH? You can set that option in ejabberdctl.cfg.

Set for example to /tmp, does then work? In that case, what username and permissions does the created path have? If you reproduce those permissions in the initial path, does then the command work?
