my lxqt session fails to start for about a day (since last night's lucky upgrade)

Some packages were upgraded fairly recently.

It usually takes one to two hours after the package has been built for it to be propagated to mirrors.

Oh, ok, I will wait a little bit more then
Thank you.

This was caused by using qt5-styleplugins. If you happen to use that library (it is set as an environment variable somewhere), it gets loaded anytime you launch a QT application. It was missed during the qt5-base upgrade which is why this happened. I have already rebuilt it against the new qt5-base, so once the mirrors propagate that should fix this issue for good.

Spot on!
qt5-styleplugins was the problem.
I already upgraded and everything Qt dependent is working great again.
Thank you very, very much. This thing was driving me nuts

PS:
Unrelated to this (or maybe not), when I updated, I saw a problem with the "expat" package:
warning: expat: local (2.4.7-1) is newer than system (2.4.6-1)
Is this problem related to the Qt one?

I've been upgraded now. My session boots normally. Thank you!
