[Bug 1782110] Re: unhelpful error message when snap is installed already
Em dashes cannot be part of a snap name. They _could_ be part of an intentional 'snap set' command, something like snap set mysnap foo=—o— in which case, if the "snap set" fails, the user will get the above message, followed by whatever error. Like so: $ snap set bofh foo=—o— Your command included some characters that look like dashes but are not: "snap set bofh foo=\u2014o\u2014" in some situations you might find that when copying from an online source such as a blog you need to replace “typographic” dashes and quotes with their ASCII equivalent. Dashes in particular are homoglyphs on most terminals and in most fixed-width fonts, so it can be hard to tell. error: cannot perform the following tasks: - Run configure hook of "bofh" snap (snap "bofh" has no "configure" hook) I think this is reasonable unless we want to actually parse the em dashes, which seems like a lot more work for this corner case. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1782110 Title: unhelpful error message when snap is installed already To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/snapd/+bug/1782110/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Are they allowed characters or forbidden? Could there be commands that "look" safe but in reality operate on pacakges with funny names?

[Bug 1782110] Re: unhelpful error message when snap is installed already
There's something very strange going on. This is what I get: $ snap install atom --classic atom 1.28.2 from 'snapcrafters' installed $ snap install atom --classic snap "atom" is already installed, see 'snap help refresh' $ the 'already installed' error is returned before even looking at the store; there's just no way to get to that error just like this. Can you reproduce this? How? If not, could you get us the output of 'snap tasks' for the change in question? (look at 'snap changes' to figure out which one it is). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1782110 Title: unhelpful error message when snap is installed already To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/snapd/+bug/1782110/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
