probably an upstream issue. Usually, the user mympd should have been created by the apt package 🤔

I see as well that config directories being moved. Probably we would need to adjust our install procedure.

jalsco · 2022-12-01T12:10:52Z

Thanks @Joulinar - just let me know if anything I can do to help 🙏🏻

MichaIng · 2022-12-01T14:12:30Z

Related to: #5919
So now that it is a "dynamic" service user, a fixed one isn't created anymore (if systemd is used): https://github.com/jcorporation/myMPD/blob/master/contrib/packaging/debian/postinst

@jcorporation
If I'm not mistaken, a dynamic user means one has no chance to grant myMPD write permissions to anywhere without 777 mode, since neither can something be owned by a dynamic user, nor can it be added to a group. How is myMPD now supposed to get write access to the MPD directories via webdav? Furthermore, I'm not sure now how to pre-create the config directory via mympd -c, since it can only have wrong permissions: #5919
Of course it is possible to pre-create the mympd system user, but this obviously breaks the intention of using a dynamic user.

Joulinar · 2022-12-01T14:16:58Z

@MichaIng
we would need to have a deeper look into MyMPD install process. Looks like existing configurations are not excepted currently. Strange behavior for an app to fail just because a config file exists. 🤔 Seems like a bug?

MichaIng · 2022-12-01T14:29:20Z

@Joulinar
Yes this is already known, see my post and linked issue above 😉. A dynamic service user basically makes pre-creation of that directory impossible, so let's see how it's intended by Jürgen.

@jalsco

- DietPi-Software | myMPD: On fresh installs, SSL is now enabled by default on the same port 1333 which was previously used for plain HTTP. For plain HTTP, now port 1332 is used, which redirects to HTTPS automatically, but currently cannot be disabled completely. - DietPi-Software | myMPD: Resolved an issue where the installation as well as the service start after latest myMPD release failed. Many thanks to @jalsco and @sofad for reporting these issues: #5936, #5919

MichaIng · 2022-12-02T18:21:24Z

PR up to solve this: #5944

It will work after next myMPD package release. Currently mympd -c will still fail, but after next release it won't. We do now use the dynamic service user to benefit from the theoretical security benefits.

Thanks so much !! You guys really rock 😁😁✨💖

jcorporation · 2022-12-04T19:57:50Z

myMPD v10.1.4 is out!

jalsco · 2022-12-05T01:25:00Z

Thanks to @jcorporation , @MichaIng and @Joulinar for getting this updated so quickly ! 🙏🏻

I did : sudo apt update && sudo apt full-upgrade
It did inidcate new version of mympd

But I am still having problems to get mympd to run - or to install successfully - on my Dietpi 😢

Maybe it is still half in and half out - because of previous failed attempts to install previous version of mympd ? Anyway , I have tried all the options of - uninstall install, reinstall... But I still have this status:

Note also - mympd - does NOT show in the - installed - list on dietpi-software, and installing via dietpi-software always fails with error message - as before

Joulinar · 2022-12-05T09:01:50Z

Yes configuration directory would need to be removed before trying again

rm -Rf /var/lib/mympd
rm -Rf /var/lib/private/mympd

Yes configuration directory would need to be removed before trying again

rm -Rf /var/lib/mympd
rm -Rf /var/lib/private/mympd

I just did that - and then tried again to install using dietpi-software , but still errors

Joulinar · 2022-12-05T09:22:50Z

probably wait un our upcoming Beta version. There we changed the install process according new mympd version.

jalsco · 2022-12-05T09:28:06Z

ok - is that very close ?

Joulinar · 2022-12-05T09:36:41Z

probably next weekend #5898

In urgent case, you could switch to development branch already.

jalsco · 2022-12-05T09:42:58Z

next week is good

MichaIng · 2022-12-05T15:02:14Z

Just in case, dev branch can be applied via:

G_DEV_BRANCH dev

And to switch back to master, once it gets released:

G_CONFIG_INJECT 'DEV_GITBRANCH=' 'DEV_GITBRANCH=master' /boot/dietpi.txt
