I first asked this question on StackOverflow but someone told me there that I have a better chance of getting an answer here

I am trying to install MySQL Workbench on my Google Pixelbook. It runs Linux debian 10 buster.

So I run these commands:

sudo apt-get update

and then

sudo apt-get install mysql-workbench

I get this error:

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:
 mysql-workbench : Depends: gdal-abi-2-1-2
                   Depends: libgdal20 (>= 2.0.1) but it is not going to be installed
                   Depends: libmysqlcppconn7v5 (>= 1.1.7) but it is not going to be installed
                   Recommends: ttf-bitstream-vera but it is not going to be installed
                   Recommends: mysql-utilities but it is not going to be installed
E: Unable to correct problems, you have held broken packages.

When I try to install these dependencies it is a never-ending story of missing dependencies like described in this post: https://askubuntu.com/questions/1005179/unable-to-install-mysql-workbench-for-ubuntu-16-04-lts

I searched a lot on several forum for a solution but nothing works. Most solutions I found was for Ubuntu and not for Debian

FYI, at first I tried to install it by downloading and installing the following file mysql-workbench-community_8.0.23-1ubuntu20.10_amd64.deb and it didn't work.. Maybe it created some kind of conflict that prevents me from installing it with apt or apt-get

Here is the content /etc/apt/sources.list

  GNU nano 3.2                                               /etc/apt/sources.list

Thanks

When I try to purge I got this:

sudo dpkg --purge mysql-workbench-community dpkg: warning: ignoring request to remove mysql-workbench-community which isn't installed sudo dpkg --purge mysql-workbench dpkg: warning: ignoring request to remove mysql-workbench which isn't installed

And when I try to install with snapd I got this

sudo snap install core

error: system does not fully support snapd: cannot mount squashfs image using "squashfs": mount:/tmp/sanity-mountpoint-750692798: mount failed: Operation not permitted.

Snapd and snap are installed:

sudo apt list snapd -a

Listing... Done
snapd/stable,now 2.37.4-1+b1 amd64 [installed]
snapd/oldstable 2.21-2+b1 amd64

sudo apt list snap -a

Listing... Done
snap/stable,now 2013-11-29-9 amd64 [installed]
snap/oldstable 2013-11-29-6 amd64

What are your thoughts dear community?

Yes, the dependency conflicts are likely due to the .deb install.

Specifically, the .deb has lots of dependencies that are not available in your upstream repositories.

Cleanup

First, get back to a clean state.

dpkg --purge mysql-workbench
apt-get autoremove

Snap

In this case, I suggest you try snapd, which is a different package manager that focuses on allowing developers to publish directly to users, rather than using distribution maintainers.

  • pro: faster release cycles
  • con: less assurance of stability/compatibility since it is not packaged by distribution maintainers.

In this case, the package you want is not in the main Debian repository, so snap is a good fallback.

Install

apt update
apt install snapd
snap install core
snap install mysql-workbench-community

  • @LouisChaussé great. You should also remove the `stretch` sources in your `/etc/apt/sources.list`. Mixing versions in your repository sources is not a good idea. –  Feb 18 '21 at 11:28

It seems that the problem was caused by the fact that chromeos was not dealing well with snapd
