Package: ftp Version: 20210827-3 Severity: normal Usertags: warnings When I upgraded the ftp binary package from 0.17-35 to 20210827-3, the tnftp invocation of update-alternatives gave a warning about the netkit-ftp alternative being missing.
The warnings is trigger by tnftp.postinst when user never install tnftp before when upgrade.
First tnftp was unpacked, then the old ftp package files removed, the new ftp transitional package files unpacked, then the tnftp postinst was run and then the ftp transitional package postinst was run. https://www.debian.org/doc/debian-policy/ap-flowcharts.html I think the correct solution is for the new ftp preinst to remove the netkit-ftp alternative before the old ftp files are removed.
Yes, it's a good way to fix this bug. I'd git commit in salsa and tested in my local: 1. apt purge ftp tnftp -y;apt -y install ftp/stable [...] 2. dpkg --debug=2 -i ./ftp_20210827-4_all.deb ./tnftp_20210827-4_amd64.deb (Reading database ... 270326 files and directories currently installed.)

There is not warnings now. I just upload the new version to mentors.d.n [1], welcome to help to review. [1] https://mentors.debian.net/package/tnftp/
Another solution might be for the tnftp postinst to remove the netkit-ftp alternative before adding the tnftp alternative. I didn't test either of the potential solutions though.
