I am very new to linux as well as Raspberry Pi. Recently bought a Raspberry Pi 4. Trying to install Monodevelop as I would like to make apps. Following the directions from Monodevelop I am getting the following error.
sudo apt-get install monodevelop
Reading package lists... Done
Building dependency tree
Reading state information... Done
Package monodevelop is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
E: Package 'monodevelop' has no installation candidate
Thinking that maybe there is something wrong with my installation I have formatted and reinstalled Raspberry Pi OS [Within Raspberry Pi Imager I have chosen Raspberry Pi OS (Other) -> Raspberry Pi OS Full (32-bit)]
Despite reinstalling the OS I am getting the exact same error.
Doing research about this error still leaves question marks as I am still not understanding 1, what the issue is 2, what are next steps to address this.
Can't remember where I came across this bit of info, but someone has mentioned trying to do a cache search as shown below you will see that Monodevelop does come pre-installed on the Raspberry Pi OS
sudo apt-cache search monodevelop

I don't know what I need to do with that bit of info. Do I uninstall those packages that it came pre-loaded with it? Really don't know what to do at this point.
Within this stackexchange a possible solution was to install gdeb to properly install the software: https://raspberrypi.stackexchange.com/a/50511/127602
Don't know if this is a valid path to go down.
Can someone make some recommendations for me try? Would really like to get Monodevelop installed. That is my hope.
Update 1:
Ran the following commmand
cat /etc/apt/sources.list.d/mono-official-vs.list
deb https://download.mono-project.com/repo/debian vs-buster main
Would like to mention that I have tried modifying the sourc list "mono-official-vs.list" file. Currently, that's what the file says.
Have in the past updated the file to include the following...
deb https://download.mono-project.com/repo/debian vs-buster main
deb https://download.mono-project.com/repo/debian buster main
Or...
deb https://download.mono-project.com/repo/debian vs-buster main
deb https://download.mono-project.com/repo/debian stable-buster/snapshots/6.10.0 main
The last one generated the following error message
W: Conflicting distribution: https://download.mono-project.com/repo/debian stable-buster/snapshots/6.10.0 InRelease (expected stable-buster/snapshots/6.10.0 but got buster)
Both of which have failed to install monodevelop. Any other suggestions that you think might help, I am all willing to try.
Update 2:
Started from scratch again. Here are the steps that I have taken.
- Raspberry Pi Imager [Formatted SD card, just in case left over data?]
- Once format was complete chosen to install "Raspberry Pi OS (32-bit) [Recommended choice]
- After installation and boot up. Ran the update recommended update when it was offered
- Once updated was completed went to Monodevelop website and followed their step-by-step guide to install their software on Debian 10 see output below...

What am I doing wrong?
