Just did a fresh install last weekend for a family member. Used the ISO off the website. Ran into an odd issue, tried to open some .7z files and Ark said it was unsupported. Did some digging and found that p7zip was not installed. Installed that and now it works. Wasn't this installed by default in the past? Or am I possibly just mis-remembering?
Also on this install the right click "extract here" context menu isn't there.
Both installs are the Plasma version. Both are fully up to date and passed a eopkg check (please don't ever remove this feature!)
