Bug#1028099: [libtepl-6-2] package upgrade error

Fri Jan 6 20:33:42 GMT 2023

Package: libtepl-6-2
Version: 6.4.0-3
Severity: serious

Ran into an upgrade issue on Sid today. Seems libtepl-6-1 did not get
removed before trying to install libtepl-6-2, causing the libtepl-6-2
install to fail, and consequently cascading failures from there.

Output of first aptitude upgrade command:

```
$ sudo aptitude upgrade

I presume maintainer simply forgot to add a 'not compatible with
libtepl-6-1' marker to libtepl-6-2.

I manually managed to resolve this by removing libtepl-6-1 and
reattempting the upgrade, but of course this needs fixing please for
everyone else. Thanks. :)
