package lyx 2.1.3-1 failed to install/upgrade: Versuch, »/usr/share/icons/hicolor/48x48/apps/lyx.png« zu überschreiben, welches auch in Paket lyx-common 2.1.3-1~utopic~ppa2 ist

[Tobias Frei]

Upgrading to vivid (15.04) using "do-release-upgrade -d" caused this error. I had to run "apt-get -f install" and "apt-get dist-upgrade" to finish the upgrade.

1) vivid (15.04)
2)
tobefree@tobefree-desktop:~$ apt-cache policy lyx
lyx:

        500 http://archive.ubuntu.com/ubuntu/ vivid/universe amd64 Packages

3) I expected an upgrade to happen.
4) Instead, an error appeared and the dist-upgrade / release-upgrade did not finish.

[Jean-Marc Lasgouttes (jmarc)]

Am I right that this is related to upgrade LyX over an older ppa version? Is this supposed to work?

Did you experience the problem again?

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[Juhani Numminen (jsonic)]

Like jmarc, I think this problem comes from the use of a PPA-provided version of lyx. Because of this, the Ubuntu project can not support or fix your particular bug. Please report this bug to the provider of the software package lyx, version 2.1.3-1~utopic~ppa2. Thanks!
