The unison binary from 18.04 (unison-2.48.4-gtk) does not run on my
20.04 machine:

Nor does the newer version run on 18.04:

'''
unison-2.48.4-gtk: /lib/x86_64-linux-gnu/libm.so.6: version `GLIBC_2.29' not found (required by unison-2.48.4-gtk)
unison-2.48.4-gtk: /lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.28' not found (required by unison-2.48.4-gtk)
'''

Any ideas for a workaround?

Title:
  unison incompatible with older ubuntu/debian versions

Status in unison package in Ubuntu:
  Confirmed

Bug description:
  Hi,

  16.04 comes with a new version of unison, which is great.

  Unfortunately, it comes just with that new version, not older ones.
  Unison can synchronize only with precisely the same version on the
  peer, not interact with others. Therefore a 16.04 machine cannot sync
  to any older linux (ubuntu,debian,...), especially not to servers
  running 14.04.

  Older versions of ubuntu therefore came with different versions of
  unison, i.e. at least the version of the last LTS version to keep it
  functional and to have new clients work with older (but still
  supported) LTS servers.
