@damadam The Legend of Heroes: Trails of Cold Steel III --speedrun-- takes about 95 hours :D

@blade19899 well what is BAD with this game: at the end you go to ng+ and can tranfer certain things into ng+ so you can keep going. This does NOT work for treasure you open. 288 of them. Need to do that in 1 playthrough ... and some of those treasure are hidden or can only be picked up at a specific moment or after a combination of events. Soooooooooo very easy to miss.

hello guys

I was using virtualenv without any problem I could create, delete enviromnets. But after the installation of Anaconda in my machine its not possible to create new virtualenv, but I can use the old ones. Whenever I try to create a new one the following error is showing:

user@user-H270M-D3H:~$ mkvirtualenv test
bash: /home/sysg/.local/bin/virtualenv: /usr/bin/python: bad interpreter: No such file or directory

How to get rid of this. What's the real problem? Any help will be greatly appreciated.

do you have a /usr/bin/python?

how to check that

I used which python and it shows the below path
/usr/local/bin/python

I am trying to understand use of pivot_root in a mount namespace. In most of the resource, explanation is more complex to me. Can anyone kindly explain the use of pivot_root with real-world use-case. Thanks

@SRJ577 how about ls /usr/bin/python

@Rinzwind
Its showing
ls: cannot access '/usr/bin/python': No such file or directory

so there is your answer :)
/home/sysg/.local/bin/virtualenv assumes /usr/bin/python exists

@Rinzwind then what should i do

fix the she bang in /home/sysg/.local/bin/virtualenv OR run it by using "python " in front of it.

see for instance stackoverflow.com/questions/2429511/…
