Dear support,

I tried install a pack we built in our gitlab, and it fails at 3rd step, detail error shown as follows:
the pack dependency: six version seems already exist, not sure why it failed.

Please help!

I finally figured problem, since our production has no internet connection, and we use our pip source repos.

after we add below line to pip.conf, the problem solved.:
trusted-host=repo.matrix.ctripcorp.com

root@a474eb9015f2:~/.pip# cat pip.conf
[global]
index-url = http://repo.matrix.ctripcorp.com/pypi/simple/
trusted-host=repo.matrix.ctripcorp.com

Thanks for double-checking.
Since it's not an issue anymore, closing then.
