cowbuilder is used, underlying file system (dedicated to debian pkgs building) is ext4.
but is it a filesystem effect somehow or just a \"partially\" isolated environment aspect (such as those pbuilder/cowbuilder chroots)? The message `gpg: can't connect to the agent: IPC connect call failed` suggests that may be tests pass for you locally as connecting to your gpg agent?

### Please describe the problem.
When you encrypt something to a master key, gpg actually encrypts to its corresponding encryption subkey, but the id of the master key gets recorded in the remote information. It is useful to be able to see the actual subkey id to make sure everything is encrypted as expected in a multi-subkey setup.
### What steps will reproduce the problem?
1. Have a master key with two encryption subkeys
2. Create a remote with `hybrid` encryption with `keyid` set to the key’s email address or master key id
3. Use `git annex enableremote keyid+=` and the `!` suffix to add the second encryption key.
4. Try to use `git annex info` to see which subkeys can be used for decryption.
### What version of git-annex are you using? On what operating system?
7.20181211
### Please provide any additional information below.
I managed to do this for myself by thaking the `cypher` from `remote.log`, decoding base64 and running it through `gpg --list-packets`, but, I guess, it would be nicer to have an easy way to do this: maybe some flag for `git annex info` to do this dance for me, or even just record the subkey in `remote.log`.

### Please describe the problem.
### What steps will reproduce the problem?
Build git-annex with GHC 8.6.
### What version of git-annex are you using? On what operating system?
7.20181211, master
### Please provide any additional information below.
Following the implementation plan for the [MonadFail Proposal](https://wiki.haskell.org/MonadFail_Proposal), GHC 8.6 has enabled `-XMonadFailDesugaring` by default.
Some of the code in git-annex uses failable patterns in `do`-blocks, so it fails to compile starting from GHC 8.6, as there is no `MonadFail` instance for `Annex`. Here is an example of such an error:
Remote/Glacier.hs:165:17: error:
• No instance for (Control.Monad.Fail.MonadFail Annex)
arising from a do statement
with the failable pattern ‘(_, Just h, _, pid)’
• In a stmt of a 'do' block:
(_, Just h, _, pid) <- liftIO $ createProcess cmd
In the expression:
do let cmd = ...
(_, Just h, _, pid) <- liftIO $ createProcess cmd
ok <- ifM
(liftIO $ hIsEOF h)
(return False, sink =<< liftIO (L.hGetContents h))
liftIO $ hClose h
....
In an equation for ‘go’:
go (Just e)
= do let cmd = ...
(_, Just h, _, pid) <- liftIO $ createProcess cmd
ok <- ifM
(liftIO $ hIsEOF h)
(return False, sink =<< liftIO (L.hGetContents h))
....
|
165 | (_, Just h, _, pid) <- liftIO $ createProcess cmd
| ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
### Have you had any luck using git-annex before? (Sometimes we get tired of reading bug reports all day and a lil' positive end note does wonders)
Just trying to start using it. I have built it with `-XNoMonadFailDesugaring` for now.

### Please describe the problem.
`git annex enable-tor` fails on Android/Termux (both when entering the command manually and in the webapp)

Sure thing! git-annex is amazing and usually works really well. Using it to keep files in sync between my pc, laptop and phone.

> If you run git annex info you can see how much of this space is from actual annexed objects local annex size
I don't understand what you mean, `git annex info` tells me nothing about the repository size, and I have no idea where to enter the “local annex size” string.
At any rate, no, I have already run `git annex dropunused` to get rid of all unused files. All the rest seems to be needed for some reason. My question was whether I can move all of this history to one of my volumes which have more space on them.

Hello, I'm having some problems using any BLAKE2 backend (tried with BLAKE2B512E, BLAKE2S256E, and BLAKE2SP256E) on an AMD Turion II Neo N40L Dual-Core Processor. Using default, WORM, or SHA3_512E backend works but after switching to a BLAKE2 variant `git annex add` and `git annex migrate` exit with a SIGILL: `add testfile2 error: git-annex died of signal 4`.

Hi. I have a git-annex repo on a FAT32 file system that only replies:
git-annex: openFile: resource busy (file is locked)
to most commands. Any hint as to what I could do to fix it? It is a v7 repo.
