Linux Install troubles
The good news is that they are solved - for me - and I have Sigil 0.7 running on LMDE 64 bits.
But I found the install
very uneasy. I do not know why, but some
locked tmp folders have been created during the install, and I could not even launch Firefox except with sudo... I had to reinstall for this reason.
Even now, I can launch Sigil only with a script giving him every time the location of the Qt5 library (this idea coming from Diap Dealer).
I hope I am alone facing these hurdles, because the number of Linux users may drop dramatically if this install is not made clearer.
Here is the install record if this can help the next one..

Beware of the paths, beware of everything...
