[Bug 1659719] Re: ssh can't call a binary from a snap without the full path

[Brian Murray]

Hello Leo, or anyone else affected,

Accepted pam into bionic-proposed. The package will build now and be
available at
https://launchpad.net/ubuntu/+source/pam/1.1.8-3.6ubuntu2.18.04.2 in a
few hours, and then in the -proposed repository.

Please help us by testing this new package.  See
https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how
to enable and use -proposed.  Your feedback will aid us getting this
update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug,
mentioning the version of the package you tested, what testing has been
performed on the package and change the tag from verification-needed-
bionic to verification-done-bionic. If it does not fix the bug for you,
please add a comment stating that, and change the tag to verification-
failed-bionic. In either case, without details of your testing we will
not be able to proceed.

Further information regarding the verification process can be found at
https://wiki.ubuntu.com/QATeam/PerformingSRUVerification .  Thank you in
advance for helping!

N.B. The updated package will be released to -updates after the bug(s)
fixed by this package have been verified and the package has been in
-proposed for a minimum of 7 days.

Bug description:
  [impact]
  ssh can't call a binary from a snap, it will only work using the full path.

  [test case]
  Create a container. Install the go snap (and make sure golang-go is not installed). Run "ssh <container-ip> go version" and check the binary is found.

  [regression potential]
  It's a pam change an they are always a bit scary but the code follows the existing pattern for updating PATH in /etc/environment and has been tested in groovy.

  [original description]

  Let's say I have the hello snap installed in 192.168.122.24. Then:

  elopio at ubuntu-xenial:~/mosh$ ssh 192.168.122.24 hello
  elopio at 192.168.122.24's password:
  bash: hello: command not found
  elopio at ubuntu-xenial:~/mosh$ ssh 192.168.122.24 /snap/bin/hello
  elopio at 192.168.122.24's password:
  Hello, world!
