[Message part 1 (text/plain, inline)]

Hello,

The accountsservice service hasn't access to dbus' interfaces throwing
an error when they're needed.The problem, at least, appears with LightDM.
The error looks like:

WARNING: Error updating user /org/freedesktop/Accounts/User1000:
GDBus.Error:org.freedesktop.DBus.Error.InvalidArgs: No such interface
"org.freedesktop.DisplayManager.AccountsService"

For information, it already occured[0] and was resolved[1][2] in NixOS.

After testing, simply wrapping the accountsservice package with relevant
XDG_DATA_DIRS directories as done in the attached patch resolves the
issue. However, there might be a proper solution I'm not aware of.
Also the patch used in [2] doesn't seem to be needed in Guix.

Have a nice day,

L  p R n  d n
