Updating to flatpak 1.14.6-1ubuntu0.1 noble.

Setting up flatpak (1.14.6-1ubuntu0.1) ...
fatal: Only one or two names allowed.
dpkg: error processing package flatpak (--configure):
 installed flatpak package post-installation script subprocess returned error exit status 51

I tried dpkg --configure -a. Same problem. I uninstalled all flatpak related, and tried reinstalling flatpak. Same problem.

installed flatpak package post-installation script subprocess returned error exit status 51

I am getting this message too!

Status changed to 'Confirmed' because the bug affects multiple users.

The bug affected me too under an up2date Ubuntu 24.04.

During installation the packet fails at the postinst step with the error message: `fatal: Only one or two names allowed.`

This error is yielded by the `adduser` execution inside of the postinst script. It has it's cause in the `--gecos "Flatpak system-wide installation helper"` option given to the command. As it seems this gecos option (which by the way is deprecated and could be replaced with --comment, however this does not influence the here described behavior) accepts one word only. As soon as one gives text with white spaces adduser results with the mentioned error. So the fix is to change this text to be one word (or omit the entire option).

[Frank Hempel (red-socks)]

The attached deb file (amd64) has the corrected gecos option in the postinst script. To overcome the half-installed flatpak run `dpkg -i flatpak_1.14.6-1ubuntu0.1_amd64.deb`.

Patched flatpak in #4 works for me.
