Simple overview:
I am using the GDebi linux package installation tool to install RStudio 1.4.1717. It generates multiple dependency errors and gives up. Attempts to resolve them have failed so far.
I also tried to install again a prior version, RStudio 1.3.959 that also fails (I think I succeeded in installing it several years ago under Neon built upon Ubuntu LTS).

Details:
RStudio has been discussed in this forum before. It is a free to individuals for non-profit use proprietary package. It is a fancier GUI front end with sizeable use for developing and modifying R language programs. (I just learned that there is a small KDE project, RKWard, that is a front end for R that I have not installed and tried yet. I would prefer to stay with RStudio that I used a good amount three years ago.)
I am running KDE Neon 5.22 with Kernel 5.4.0-73-generic (64 bit)
I have the Muon Package Manager 5.8.0 (It can access the libc6-i386, etc. but it won't let me Install it--the "Apply Changes" button is greyed out. It is similar with the other 32-bit libraries that the installation attempts identify.
There is discussion also in the Kubuntu community about Muon not being maintained, etc. and that Neon does not support it. I found warnings about directly installing one of the 32 bit libraries potentially causing problems. It might be done with Pkcon. (Maybe there is a way with Discover to resolve this, but I don't know what that would be.)

I am hoping one of the experienced and insightful persons here knows a reasonable path forward.

Here is my last attempt:

You would need to enable 32 bit support ('Multiarch').
Neon does not have 32 bit support turned on by default, but it is easy to enable. After getting that, update your system and try again.

Also, Gdebi it is not necessary on Neon as Discover handles deb files without it.

Thanks, claydoh,

I followed the advice on Linode above to install Multiarch support
I verified i386 support.

I tried to install rstudio-1.4.1717-amd64.deb using Discover and was told it failed because of dependencies.
I tried gdebi also and got more details. I then tried installs of libraries. All failed.

Any suggestions?

I don't know. I had no issues installing the package myself.
Did you update before trying to install the package? You may need to update the package list after enabling 32 bit, not sure if it does this automatically.


However I noticed this:

Code: Select all

Fatal error: The following packages have unmet dependencies:
libc6-i386: Depends: libc6 (= 2.31-0ubuntu9.2) but 2.31-0ubuntu9.3 is to be installed

Now, libc6 should be 2.31-0ubuntu9.2) and your system wants to install 2.31-0ubuntu9.3. This is newer than what is in the normal repos:

Here is mine:

Code: Select all

$ apt policy libc6
libc6:
  Installed: 2.31-0ubuntu9.2
  Candidate: 2.31-0ubuntu9.2
  Version table:
 *** 2.31-0ubuntu9.2 500

        100 /var/lib/dpkg/status
     2.31-0ubuntu9 500
        500 http://archive.ubuntu.com/ubuntu focal/main amd64 Packages


I wonder if you are seeing this bug:
https://bugs.launchpad.net/ubuntu/+sour ... ug/1926918

That bug looks ugly.

Here is what I got:
jim@tabby7:~/Downloads$ apt policy libc6
libc6:

Do I dare trying
pkcon install libc6=2.31-0ubuntu9.2

It may be failsafe if it prompts for the OK to remove > 100 packages.

Would I have to request the 9.3 version's removal?

I will do a bike ride.....

I'd suggest using apt for this job, pkcon might not show all of what it is asking apt to do, though it probably does

this will simulate the process without performing any actual changes:

Code: Select all

sudo apt install --dry-run libc6=2.31-0ubuntu9.2

It wants to remove lots.
There's a long listing. I will try the List button to make it compact.
Sorry, it did not work. How can I put in a scrolling listing. I was not able to find out how?
