How to Install Sigil 0.9.8 in Ubuntu / Linux Mint:

Sigil does not offer official Linux binaries. Besides building from the source tarball, you may install Sigil 0.9.8 via my personal PPA.

1. Open terminal by pressing Ctrl+Alt+T or searching for “Terminal” from start menu. When it opens, run command to add the PPA:

sudo add-apt-repository ppa:ubuntuhandbook1/sigil

Type in your password (no visual feedback due to security reason) and hit Enter.

2. Then you can upgrade Sigil editor from an existing release via Software Updater:

Or install /upgrade Sigil via commands:

sudo apt update

sudo apt install sigil

In Addition, for Linux libxml2 bug see HERE. Sorry that I can’t build it with DBUILD_PATCHED_LIBXML2=1 option since it requires cloning source from github.com but Launchpad builders do not have internet access.
