For me it behaves as expected and does not allow removing it

[root@JollaC2 ~]# pkcon remove libxml2

Fatal error: This request will break your system!

What do you have in /etc/zypp/systemCheck.d/ ?
Did it remove anything else when you removed libxml2?

Same here on C2 (20 chars…)

Same as in it allows you to remove libxml2 or not?

No, same as in your post, screams about breakage and blocks

Ok, weird. Thanks for testing. Will have to retest.

/etc/zypp has:

nemo@PGJollaC2:~ $ md5sum /etc/zypp/systemCheck.d/*
09a16f863312cdcdd5e821dc693ff17c  /etc/zypp/systemCheck.d/feature-jolla.check
9b883c009c2a88e58d2f4665dd1659d6  /etc/zypp/systemCheck.d/ha.check
3e7c7b8511f7e0799ace4b4bae6b7a30  /etc/zypp/systemCheck.d/jolla-core.check

I did remove other things in the same go, unfortunately the exact command has dropped from shell history by now.

Zypp history indicates that the removal was two packages of my own making, plus libxml2.

zypp history snippet:

libass and libfmt are two I built myself.
