* rootless: Tell the user what was led to the error, not just what it isAndrej Shadura2021-04-27
| | | | | | | | | | | | | | | | | | Users coming e.g. from Docker do not always read the manual and expect podman to not require sudo or uidmap, for them the default message is not very helpful: Error: Cannot connect to the Podman socket, make sure there is a Podman REST API service running.: cannot find newuidmap: exec: "newuidmap": executable file not found in $PATH Adding a bit more context to this would help to nudge them into the right direction and tell them what to look for in the documentation: command required for rootless mode with multiple IDs: exec: "newuidmap": executable file not found in $PATH Signed-off-by: Andrej Shadura <andrew.shadura@collabora.co.uk> [NO TESTS NEEDED]

* Switch references of /var/run -> /runDaniel J Walsh2021-01-07

* [CI:DOCS] Add note on run image fuse problem - try 2TomSweeneyRedHat2020-09-04
| | | | | | | | | | | | | | | | | | We've recently had a number of issues reported against our pre-fabricated images on quay.io and a couple of rhel repositories throwing a fuse error when run: ``` fuse: device not found, try 'modprobe fuse' first ``` The tip on modprobe fuse is not always seen by or displayed to the end user. Adding a couple of doc pointers to hopefully help. Arises from this BZ: https://bugzilla.redhat.com/show_bug.cgi?id=1867892 and several others.

* troubleshooting: Add console syntax highlightingW. Trevor King2018-05-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | These blocks include both shell input and command output. GitHub uses Linuguist for syntax highlighting [1]. Linguist defines a ShellSession language to highlight those [2], although I prefer the shorter 'console' alias. This commit also makes this file more consistent about including the leading prompt and sudo. I'd also be fine using the traditional '#' prompt for privileged users instead of '$ sudo', to be less opinionated about *how* the user acquires the privileges (via sudo or otherwise). Linguist's shell-session grammar is from Atom [3], and that grammar recognizes any of >$#% as the final prompt character [4]. But I've left this facet alone for now.
