SourceTree cask install fails

[kenahoo]

I just tried to install the sourcetree cask, but it failed like so:

% brew cask install sourcetree
==> Caveats
Cask sourcetree installs files under "/usr/local".  The presence of such
files can cause warnings when running "brew doctor", which is considered
to be a bug in homebrew-cask.

Looks like a permissions issue, does the installer need to run with higher privileges?

My version:

% brew --version
0.9.5 (git revision 407c6; last commit 2015-10-01)

This looks like a duplicate of https://github.com/caskroom/homebrew-cask/issues/7750.

I'm not at this machine anymore and won't be again until Monday, but I do know I installed some non-brew packages, notably LaTeX stuff like MacTeX, and perhaps that screwed around with permissions on /usr/local.

[dardo82]

Then check it out and don't forget to close this issue if you find out it's not homebrew-cask's fault.

Not a problem here, I'm on 10.11. Make sure you run brew doctor and fix permissions as it asks.

@adidalal - I'm sure it's not sourcetree's fault, but I'm not sure where to direct blame. Any suggestions for figuring out whether MacTeX is messing things up, without getting a fresh machine (which I don't have) & installing again?

[dardo82]

Could you virtualize the the fresh machine?

[adidalal]

@kenahoo Run brew doctor and check the output, you'll need to sudo chown -R $(whoami):admin /usr/local to fix permissions after upgrading (it'll tell you in the output)

[kenahoo]

I should clarify - I do know it's a permissions problem on directories in /usr/local, and how to fix it (I prefer doing sudo chown root:admin /usr/local/{bin,share,man,man/man1} and sudo chmod g+w /usr/local/{bin,share,man,man/man1}, because I don't want those directories owned by my personal user), but I don't know how they got their permissions changed.

My brew doctor now looks like this: https://gist.github.com/kenahoo/e5a39fe38ce627f3ac98 .

So I'm confident it's not sourcetree's fault, but I suspect it's some other package that's not playing well with homebrew - MacTeX comes to mind just because I did install it recently, using brew cask install mactex, which gave me /opt/homebrew-cask/Caskroom/mactex/20150613/mactex-20150613.pkg . I'd like to figure out whether that's being naughty.

[kenahoo]

I ran a 'verify' on the MacTeX package (after fixing the permissions on a small handful of directories to make homebrew happy) and got some output: https://gist.github.com/kenahoo/a0d2c48d60b1f22a0c70

So it seems confirmed that the mactex cask is messing up permissions for the rest of homebrew, right? Should the cask try to clean up after itself after installing?

[adidalal]

See https://www.tug.org/mactex/elcapitan.html

Looks like you may have to manually follow this once to upgrade your symlinks, but it shouldn't be a problem with a fresh install.

Alternatively, see if brew uninstall mactex and then following the uninstall guide, and finally reinstalling fixes things. (It should, there's nothing in the cask which should cause a problem afaik)

[kenahoo]

I don't have El Capitan installed, I'm still on Yosemite. Would any of this manifest on Yosemite?

[kenahoo]

@adidalal When you say "there's nothing in the cask which should cause a problem" - what's that based on? Unless I'm interpreting it wrong, it seems like the org.tug.mactex.texlive2015 bundle, which the mactex cask installs, makes some permissions changes that are incompatible with Homebrew.

[adidalal]

According to this StackOverflow post that is not the case - only usr/local/texlive is touched by the installer (and your $PATH, it seems)

[adidalal]

@kenahoo any update?

Regardless, it looks like if there any issues, it'd be with the mactex cask, not sourcetree cask - and I get no errors with a clean install of either formula, for what it's worth

No further reply and this seems to be have affected only one user, so closing.
