Public bug reported: After upgrading my installation to 20.04, I decided to remove all repositories and keep the Ubuntu repositories in sources.list as they were not supported to file this report. I ran "sudo apt update" and removed all packages from all repositories that are not Ubuntu.
When I inspected what mono-* packages were installed, I saw that one of them, which is mono-xbuild, is installed. However, when I ran "xbuild", I saw this following line: >>>> xbuild tool is deprecated and will be removed in future updates, use msbuild instead <<<< So I went ahead and ran "apt list msbuild" and saw nothing, which is weird considering that xbuild is deprecated and that it recommends to use msbuild, which is not available yet. Even worse, the project that I was building requires at least msbuild 15.0. This is what "xbuild /version" returned: XBuild Engine Version 14.0 Mono, Version 6.8.0.105 Copyright (C) 2005-2013 Various Mono authors "lsb_release -rd" output: Description: Ubuntu 20.04 LTS Release: 20.04 "apt-cache policy mono-xbuild" output: mono-xbuild: Installed: 6.8.0.105+dfsg-2 Candidate: 6.8.0.105+dfsg-2 Version table: *** 6.8.0.105+dfsg-2 500 500 http://sy.archive.ubuntu.com/ubuntu focal/universe amd64 Packages 100 /var/lib/dpkg/status ProblemType: Bug DistroRelease: Ubuntu 20.04 Package: mono-xbuild 6.8.0.105+dfsg-2 ProcVersionSignature: Ubuntu 5.4.0-26.30-generic 5.4.30 Uname: Linux 5.4.0-26-generic x86_64 ApportVersion: 2.20.11-0ubuntu27 Architecture: amd64 CasperMD5CheckResult: skip CurrentDesktop: ubuntu:GNOME Date: Wed Apr 29 12:25:08 2020 InstallationDate: Installed on 2019-07-21 (282 days ago) InstallationMedia: Ubuntu 19.10 "Eoan Ermine" - Alpha amd64 (20190715) PackageArchitecture: all SourcePackage: mono UpgradeStatus: No upgrade log present (probably fresh install) ** Affects: mono (Ubuntu) Importance: Undecided Status: New ** Affects: mono (Debian) Importance: Unknown Status: Unknown ** Tags: amd64 apport-bug focal third-party-packages ** Bug watch added: Debian Bug tracker #959045 https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=959045 ** Also affects: mono (Debian) via https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=959045 Importance: Unknown Status: Unknown ** Bug watch added: Debian Bug tracker #959043 https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=959043 ** Changed in: mono (Debian) Remote watch: Debian Bug tracker #959045 => Debian Bug tracker #959043 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1875850 Title: mono-xbuild is deprecated but there is no replacement To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mono/+bug/1875850/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
