Repository version of Sigil won't run on all Ubuntu 20.04 systems.

[Kent Lion]

I doubt there's much point in asking a question about this, because a couple of hours searching the Internet turned up nothing on this problem, on launchpad.net or anywhere else.

When I try to run Sigil 1.1 installed from the Canonical repository on a Dell Optiplex GX620 running 64 bit Xubuntu 20.04 installed from an iso (because do-release-upgrade failed beyond repair), I get the error message:
/usr/local/lib/sigil/sigil: error while loading shared libraries: libpython3.6m.so.1.0: cannot open shared object file: No such file or directory

That tells me that libpython3.6m.so.1.0 doesn't exist (which it doesn't), but on a Dell Optiplex 780 on which do-release-upgrade was successful (but only after I completely removed gnuradio and snap), libpython3.6m.so.1.0 also does not exist, but Sigil 1.1 works.

I found very few references to libpython3.6m.so.1.0 on the Internet, none relating to Sigil, and none that helped (including one that suggested installing python3-venv, which installed successfully, but told me I needed to install python3-venv when I entered pyvenv --help or python3-venv --help).

So I can't tell if this is a bug, or due to a capability missing from the older GX620, or to a forgotten error message being triggered that is no longer valid and therefore tells nothing about the error that triggered it...

Hi,

I just tried, and here sigil runs seamlessly on focal.

I can't imagine how it could be looking for libpython3.6m.so, when sigl in focal was built against python 3.8.

Can we double checkout that you are actually running the sigil I expect you to? Please run

sha256sum /usr/lib/x86_64-linux-gnu/sigil/sigil

and try to run that binary instead of plain `sigil`
