Witam!
W ogólnej pomocy znalazłem taki opis:
Installation
Debian 9 Stretch
1. Download the latest Adobe Flash Player for Linux from https://get.adobe.com/flashplayer/
On 64bit systems, it should be: flash_player_npapi_linux.x86_64.tar.gz
On 32bit systems, it should be: flash_player_npapi_linux.i386.tar.gz
Alternatively, you can download it from: https://get.adobe.com/flashplayer/otherversions/
2. Unpack the tar.gz file: tar -xzf flash_player_npapi_linux*.tar.gz
3. Identify the location of the browser plugins directory, based on your Linux distribution and Firefox version:
Example: Debian 9 Stretch + Firefox 52.4.0 (64-Bit): /usr/lib/mozilla/plugins/
4. Copy libflashplayer.so to the appropriate browser plugins directory: sudo cp libflashplayer.so <browserpluginlocation>
Example: sudo cp libflashplayer.so /usr/lib/mozilla/plugins/
5. Copy the Flash Player Local Settings configurations files to the /usr directory: sudo cp -r usr/* /usr
Wszystko rozumiem krok po kroku oprócz pkt. 5.
Co mam tam zrobić i co skopiować do /usr?
