===== Troubleshooting =====

==== nss-pem-1.0.3-6.fc27.x86_64 does not belong to a distupgrade repository ====
On upgrading Fedora 27→28, the aforementioned error occurs. This seems to be due to [[https://bugzilla.redhat.com/show_bug.cgi?id=1553646|a bug]] related to dnf.

Solution: <code bash>dnf install nss-pem-1.0.3-9.fc28 --releasever=28</code>

==== OMEMO doesn't work in Gajim ====
<code bash>dnf install python3-devel
python3 `which pip` install python-axolotl</code>
