Hello, I cannot install Mono Develop on Debian.
* First way Package downloaded from here ( https://packages.debian.org/jessie/all/monodevelop/download) does not work because of this error: Cannot install 'libglade2.0-cil'. The details (Lintian output) were as follows: W: monodevelop: debian-news-entry-has-unknown-version 0.18.1-1 E: monodevelop: debian-copyright-file-uses-obsolete-national-encoding at line 23 W: monodevelop: manpage-has-errors-from-man usr/share/man/man1/mdtool.1.gz 104: warning: macro `/'' not defined E: monodevelop: menu-icon-not-in-xpm-format usr/share/icons/hicolor/scalable/apps/monodevelop.svg W: monodevelop: script-not-executable usr/lib/monodevelop/AddIns/MonoDevelop.Autotools/templates/autogen.sh.template W: monodevelop: script-not-executable usr/lib/monodevelop/AddIns/MonoDevelop.Autotools/templates/configure.template W: monodevelop: script-not-executable usr/lib/monodevelop/AddIns/MonoDevelop.Autotools/templates/exe.wrapper.in.template W: monodevelop: executable-not-elf-or-script usr/lib/monodevelop/AddIns/MonoDevelop.XmlEditor/schemas/appconfig.xsd W: monodevelop: executable-not-elf-or-script usr/lib/monodevelop/AddIns/MonoDevelop.XmlEditor/schemas/XMLSchema.xsd W: monodevelop: executable-not-elf-or-script usr/lib/monodevelop/AddIns/MonoDevelop.XmlEditor/schemas/W3C-License.html W: monodevelop: executable-not-elf-or-script usr/lib/monodevelop/AddIns/MonoDevelop.XmlEditor/schemas/xslt.xsd W: monodevelop: executable-not-elf-or-script usr/lib/monodevelop/AddIns/MonoDevelop.XmlEditor/schemas/nant.xsd W: monodevelop: executable-not-elf-or-script usr/lib/monodevelop/AddIns/MonoDevelop.AspNet/Schemas/readme.txt W: monodevelop: executable-not-elf-or-script usr/lib/monodevelop/AddIns/MonoDevelop.XmlEditor/schemas/manifest.xsd W: monodevelop: executable-not-elf-or-script usr/lib/monodevelop/AddIns/MonoDevelop.XmlEditor/schemas/readme.txt W: monodevelop: executable-not-elf-or-script usr/lib/monodevelop/AddIns/MonoDevelop.AspNet/Schemas/W3C-License.html Lintian finished with exit status 1 * Second way These three commands ( http://www.mono-project.com/docs/getting-started/install/linux/#debian-ubuntu-and-derivatives) worked so my package repository was updated. But then thing described in 'Usage' section did not: root@myusername:~# sudo apt-get install mono-devel Reading package lists... Done Building dependency tree Reading state information... Done Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming. The following information may help to resolve the situation: The following packages have unmet dependencies: mono-devel : Depends: libgdiplus (>= 2.6.7) but it is not going to be installed Depends: libmono-system-design4.0-cil (>= 1.0) but it is not going to be installed Depends: libmono-system-drawing4.0-cil (>= 3.0.6) but it is not going to be installed Depends: libmono-system-messaging4.0-cil (>= 2.10.1) but it is not going to be installed Depends: libmono-system-runtime4.0-cil (>= 2.10.1) but it is not going to be installed Depends: libmono-system-servicemodel-activation4.0-cil (>= 1.0) but it is not going to be installed Depends: libmono-system-servicemodel-web4.0-cil (>= 3.2.1) but it is not going to be installed Depends: libmono-system-servicemodel4.0a-cil (>= 3.2.3) but it is not going to be installed Depends: libmono-system-web-extensions4.0-cil (>= 2.10.3) but it is not going to be installed Depends: libmono-system-web-services4.0-cil (>= 1.0) but it is not going to be installed Depends: libmono-system-web4.0-cil (>= 2.10.3) but it is not going to be installed Depends: libmono-system-windows-forms4.0-cil (>= 1.0) but it is not going to be installed Depends: libmono-cil-dev (= 4.2.2.30-0xamarin2) but it is not going to be installed E: Unable to correct problems, you have held broken packages. Similar thing for the second package in 'Usage'. How to install Mono Develop (for C# development of Android apps) on Debian Linux? Thank you!
