Ubuntu 21.04 mono-devel_6.8.0.105+dfsg-3_all.deb install failed

[Mampionona Randrianirina]

When installing mono-devel_6.8.0.105+dfsg-3_all.deb on xubuntu 21.04, there is an error of dependency not met and it is saying: trying to overwrite '/usr/bin/disco', which is also in package discodos 1.0~rc2-1

Thanks for taking your time to report this issue and help making Ubuntu better.

The root problem is that both these packages contains the file '/usr/bin/disco' which cause issues when attempting to install both at the same time. See also the corresponding Debian bug report.

Yes and how does an end user resolve the problem?

[David Aguiar de Aquino (draxdeveloper)]

Ok, I am using ubuntu studio, thus I had discodos even if I not use it.

I was with full broken apt and thus I could not even purge discodos

Then I used

sudo dpkg -l | grep '^rc' | awk '{print $2}' | xargs dpkg --purge discodos

If it's says it's need superuser even if you are using sudo
Sudo su
It will open the superuser terminal, use
sudo dpkg -l | grep '^rc' | awk '{print $2}' | xargs dpkg --purge dicodos

And then close the terminal, for safety reasons

thank you David @draxdeveloper,
this solved the issue for me on ubuntu studio 22.04.

unfortunately discodos and mono both use the 'disco' command, probably making it impossible to install both packages on the same system at the same time as of right now.

Hi, I am the initial uploader of the discodos package. I'd like to remove it from the Debian and Ubuntu repositories entirely to not only solve this issue but also because I don't have the resources to maintain the Debian package anyway. How would I proceed to getting it removed?

In the meantime users running into this issue, here is the direct link on how to install DiscoDOS into the user's home and thus make it possible to co-exist with mono-devel: https://discodos.readthedocs.io/en/latest/CONTRIBUTION.html#macos-or-linux-install-to-user-environment

You can subscribe Ubuntu package archive admins (https://launchpad.net/~ubuntu-archive), either on this issue or by reporting a separate removal request in the form of a bug report. They can remove it from the current Ubuntu development release. Not sure about the Debian process, but would assume that also requires a bug report of some sort, which might be useful to reference.

This bug was fixed in the package discodos - 1.1-1

---------------
