Comment 2 for bug 1659719

Comment from ogra in the mailing list:

bash actually checks the calling process and will not source the env if
it is invoked by sshd or rshd as non-login shell (it checks if
the SSH_CLIENT environment variable is set and uses a different code
path internally).

the follwing works:

$ ssh 192.168.2.91 env|grep PATH
PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/
games:/usr/local/games

$ ssh 192.168.2.91 bash -lc env|grep PATH
PATH=/home/ogra/bin:/home/ogra/.local/bin:/usr/local/sbin:/usr/local/bi
n:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin

you could also do something like:
ssh 192.168.2.91 "source /etc/profile; hello"

i dont think we have a bug open for this and technically it is expected
behaviour (not different from any other ubuntu install), but given how
annoying it is i guess you should file one and we should find a proper
workaround or fix to ship in the image ...
