Thunar Shares Plugin 'net usershare' error 255

Support Xfce
10

thunar-shares-plugin does not work since quite some time. I am a bit surprised that actually, there seems to be only low interest in that topic. See Thunar Shares Plugin 'net usershare' error 255 - #8 by ondara for a reference.

Currently, thunar-shares-plugin seems to be broken.
It starts with the fact that there are at least three different thunar-shares-plugin packages available when you search in pamac.

The first, thunar-shares-plugin-manjaro, does not seem to work at all. You simply do not get the Share tab when clicking a folder’s properties. Even tried a reboot, to no avail.

The second, thunar-shares-plugin (without the -manjaro suffix) just spits out the following errors:

Calling "net usershare" created error 255: [2022/01/22 17:25:39,0] ../../lib/util/debug.c:1100(reopen_one_log)
reopen_one_log: Unable to open new log file 'shared/log.net': No such file or directory
net usershare add: share name /home/gerd/shared contains invalid characters (any of %<>*?|/\+-=;:,)

Of course, creating an empty file shared/log.net does not help. And there are also no illegal chars in the path to the folder to be shared.

Finally, I tried thunar-shares-plugin-gtk but it shows the same net usershare add error as thunar-shares-plugin.
According to Thunar Shares Plugin 'net usershare' error 255 - #8 by ondara, this has been introduced by a recent Manjaro update.

UPDATE: The solution is provided by @megavolt here: Samba Nautilus-Share funktioniert nicht mehr - #20 by megavolt

  1. Run makepkg --syncdeps, let it install the dependencies and have a look if it is able to create the package.
  2. Install the newly made package with sudo pacman -U thunar-shares-plugin-0.3.1-1-x86_64.pkg.tar.zst and replace all other versions of thunar-shares-pluigin.
  3. Important: Log out and back in to your X session, or reboot.
  4. Finished: thunar-shares-plugin works again!
