Arman Khan's questions

I'm trying to install InkScape on Ubuntu 19.04 from Discover (KDE plasma store), but it shows error:

Dependencies resolution failed

I tried installing it from PPA

sudo add-apt-repository ppa:inkscape.dev/stable
sudo apt install inkscape -y

but it still shows dependencies unmet. This package or dependency is unmet.

The following packages have unmet dependencies:
inkscape : Depends: libpoppler82 (>= 0.71.0) but it is not installable
            Recommends: python-uniconvertor but it is not installable
E: Unable to correct problems, you have held broken packages.

How to install it, I can't find any solution. Any help will be appreciated.

I recently updated to Ubuntu 19.04 from 18.10.

In this version, RAM consumption is more than before. Also, my PC lags every time I open a new app. Sometimes many apps respond with a force quit option.

In 18.10 everything was working nicely with no more than 2 GB RAM consumption.
