I wanted to remove a build target and got this
$ sfdk tools tooling remove SailfishOS-4.6.0.11EA
^CFailed to list installer-provided packages
(meaning: the error showed up after pressing ctrl-C because nothing was happening for some time. nothing in strace was happening).
With the above list of libraries install, the “solution” was to just log back into X11 and use ssh -X… to use the graphical uninstall method which worked.
So not only is the installation not possible without X libs, removing some things is broken too…
