Hmm... no such file or directory ?
Unfortunately I don't know well the "dpkg" package manager (enigma core OE 2.2+), but I only know the "opkg" package manager (enigma core OE 1.6 / 2.0 or derived OE-Alliance Group).
There were similar problems before. Uninstall and install problem. Some CONTROL / DEBIAN scripts in the case of the "dpkg" manager probably also need delivery parameters, because they behave slightly differently than in the case of the older "opkg" manager. A similar problem has already been seen with regard to installing and reinstalling the plugin on the OE 2.5 core. You probably have an even newer core (since you're using the latest Dreambox genuine firmware). That's why I tried to solve this by gradually uninstalling and then reinstalling it: https://github.com/s3n0/e2plug…icons/src/plugin.py#L1057
Of course I have already treated it in CONTROL / DEBIAN scripts, as someone advised me above - since I do not know well "dpkg" package manager. I do not own any set-top box with OE 2.2 or 2.5 and higher (for a testing purpose).
It is also possible that you were using an older version of the ".deb" plugin package, which used old scripts and maybe they failed the installation. I hope it will be OK from now on. If not, then write about the problem again ;-).
