Did you recently update libmount1:i386 to version 2.35.2-5 or later?

If yes, then this is probably #963525, which is a bug in the proprietary
upstream Steam binaries, triggered by extra dependencies being added
to Debian's libmount1, and cannot be fixed by the Debian steam
package. Because this is to do with the upstream Steam binaries, it
affects all versions of this package, not just 1.0.0.63-1.

Workarounds include (any one of these will probably work, choose
whichever one looks least bad to you):

- Downgrade libmount1:i386 to 2.35.2-4 and put it on apt hold for now
- Remove libglib2.0-0:i386 (this only works if you do not have packages
  that need it, such as 32-bit Wine)
- Install Steam from Flathub instead of via the steam package

This is unsupported, and its probability of working successfully drops
over time as we get further away from the Steam binaries' minimal
distribution (Ubuntu 12.04). Since it's now 8 years since the release
of that base distribution, there's basically no chance of it working
(you would have to construct a special OS distribution around Steam's
expectations, which is basically what the Steam Runtime is).
