Checksum mismatch in deb package for .desktop files

Sijainti: Vianhallintajärjestelmät: Github
Avainsanat: Debian, Ubuntu, VSCode

  • VSCode Version: 1.53.0
  • OS Version: Ubuntu Linux 20.04

Steps to Reproduce:

  1. install .deb package
  2. run debsums -s

Does this issue occur when all extensions are disabled?: Yes

I’d like to resurrect #37762: the checksums for .desktop files included in the .deb archive fail to pass post-install.

$ debsums -s code
debsums: changed file /usr/share/applications/code.desktop (from code package)
debsums: changed file /usr/share/applications/code-url-handler.desktop (from code package)

This happens because the postinst script calls desktop-file-install for the .desktop files, which adds an X-Desktop-File-Install-Version entry to them, and hence the checksums change.

I don’t know why the desktop-file-install call is there, as including the .desktop files in the deb archive is sufficient to have them installed (in their proper place under /usr/share/applications/), with the checksum intact.

I built the package with just those desktop-file-install calls removed (see below), after which the checksums pass post-install (with no other changes that I can see).
