Hello Marius Thanks for the reply. This installation is using supervisor with uwsgi to run Galaxy using a virtualenv, and I did wonder why my install wasn't picking up Mercurial from there.
Based on your suggestion it turned out that I needed to add an 'environment' parameter like e.g.: environment = VIRTUAL_ENV="/srv/galaxy/venv",PATH="/srv/galaxy/venv/bin:%(ENV_PATH)s" to the supervisor .ini file in order to get the virtualenv on the PATH. (I thought I'd tried this before without success but it works now, so I must have done something wrong previously - possibly a type in a path.) (Also, a comment re the documentation: in the "Scaling and Load Balancing" section of the docs, the 'environment' parameter is only mentioned for handler processes and doesn't appear in the example config for web processes: https://docs.galaxyproject.org/en/master/admin/scaling.html#supervisord and since I don't have any handlers (I'm using the uwsgi + mules strategy) it didn't occur to me that I would need it. It might be useful if the docs clarified that 'environment' is also required for the web processes in this case.)

If you're running galaxy in a virtualenv then that virtualenv should have the `hg` script in the bin folder. Depending on how you start galaxy you may need to add the virtualenv's `bin` folder to the `PATH`. Hope that helps, Marius On 25 June 2018 at 07:51, Peter Briggs <[email protected]<mailto:[email protected]>> wrote: Dear devs I've encountered what appears to be a subtle bug with release 18.05, which breaks the installation of tools from the toolshed, and appears to be a result of not having mercurial (hg) available in /usr/bin on the system that Galaxy is installed on (in this case Scientific Linux 6.5). When attempting to install a tool (e.g. devteam/fastqc) from the main toolshed via the admin interface, after clicking "install" the tool installation status goes immediately to "Error". The tool repository isn't cloned to "shed_tools" and no dependencies are installed. I've been unable to find any error messages in the logs. However, attempting to install via the API does return the message: Error cloning repository: [Errno 2] No such file or directory which comes from the "clone_repository" function in lib/tool_shed/util/hg_util.py (when something goes wrong with the "hg clone ..." command). Installing Mercurial 1.3 via yum on the server and attempting tool installation again gives a slightly different error via the API: Error cloning repository: Command '['hg', 'clone', '-r', u'17', u'https://toolshed.g2.bx.psu.edu/repos/devteam/fastqc', u'/XXXXXXXXXXXXXX/shed_tools/toolshed.g2.bx.psu.edu/repos/devteam/fastqc/c15237684a01/fastqc'<http://toolshed.g2.bx.psu.edu/repos/devteam/fastqc/c15237684a01/fastqc'>]' returned non-zero exit status 255 Output was: abort: No such file or directory: /XXXXXXXXXXXXXXXXXX/shed_tools/toolshed.g2.bx.psu.edu/repos/devteam/fastqc/c15237684a01/fastqc<http://toolshed.g2.bx.psu.edu/repos/devteam/fastqc/c15237684a01/fastqc> Uninstalling the system Mercurial and instead installing version 3.7.3 and making a link from /usr/bin/hg seems to fix the problem, and tools can be installed without problems. I couldn't find any evidence of this being reported before, and I don't know if I've missed some configuration detail which means that Galaxy isn't picking up hg from its virtualenv instead of /usr/bin. Has anyone else encountered this problem? and is there a fix/workaround for it (other than horrible links to /usr/bin/hg)? Any advice gratefully received!
