I followed the test case on a focal system whose sources.list file I changed to hirsute and had no issues.

[Test Case] This can be simply tested with a focal schroot: 1) apt-get install vim libsignon-glib-dev 2) edit /etc/apt/sources.list replacing focal with hirsute 3) apt-get update 4) apt-get install libsignon-glib-dev With the version of libsignon-glib-dev from -proposed you'll no longer receive the 'dpkg: error' from below. Unpacking gir1.2-signon-2.0:amd64 (2.1-3) ... dpkg: error processing archive /var/cache/apt/archives/gir1.2-signon-2.0_2.1-3_amd64.deb (--unpack): trying to overwrite '/usr/lib/python3/dist-packages/gi/overrides/Signon.py', which is also in package gir1.2-signon-1.0 1.14+17.04.20161117-0ubuntu5 Errors were encountered while processing: /var/cache/apt/archives/gir1.2-signon-2.0_2.1-3_amd64.deb E: Sub-process /usr/bin/dpkg returned an error code (1) Probably needs a conflicts/replaces dependency added to the newer hirsute package. [Regression Potential] We are adding a replaces with gir1.2-signon-1.0 so anything that depends on that package would be broken but given that that package is no longer available after focal that seems fine.
