    <p>I had a similar problem. My laptop ran out of battery during a git operation. Boo. </p> <p>I didn't have any backups. (N.B. Ubuntu One is not a backup solution for git; it will helpfully overwrite your sane repository with your corrupted one.)</p> <p>To the git wizards, if this was a bad way to fix it, please leave a comment. It did, however, work for me... at least temporarily. </p> <p>Step 1: Make a backup of .git (in fact I do this in between every step that changes something, but with a new copy-to name, e.g. .git-old-1, .git-old-2, etc.): </p> <pre><code>cp -a .git .git-old </code></pre> <p>Step 2: Run <code>git fsck --full</code></p> <pre><code>nathanvan@nathanvan-N61Jq:~/workspace/mcmc-chapter$ git fsck --full error: object file .git/objects/8b/61d0135d3195966b443f6c73fb68466264c68e is empty fatal: loose object 8b61d0135d3195966b443f6c73fb68466264c68e (stored in .git/objects/8b/61d0135d3195966b443f6c73fb68466264c68e) is corrupt </code></pre> <p>Step 3: Remove the empty file. I figured what the heck; its blank anyway. </p> <pre><code>nathanvan@nathanvan-N61Jq:~/workspace/mcmc-chapter$ rm .git/objects/8b/61d0135d3195966b443f6c73fb68466264c68e rm: remove write-protected regular empty file `.git/objects/8b/61d0135d3195966b443f6c73fb68466264c68e'? y </code></pre> <p>Step 3: Run <code>git fsck</code> again. Continue deleting the empty files. You can also <code>cd</code> into the <code>.git</code> directory and run <code>find . -type f -empty -delete -print</code> to remove all empty files. Eventually git started telling me it was actually doing something with the object directories: </p> <pre><code>nathanvan@nathanvan-N61Jq:~/workspace/mcmc-chapter$ git fsck --full Checking object directories: 100% (256/256), done. error: object file .git/objects/e0/cbccee33aea970f4887194047141f79a363636 is empty fatal: loose object e0cbccee33aea970f4887194047141f79a363636 (stored in .git/objects/e0/cbccee33aea970f4887194047141f79a363636) is corrupt </code></pre> <p>Step 4: After deleting all of the empty files, I eventually came to <code>git fsck</code> actually running: </p> <pre><code>nathanvan@nathanvan-N61Jq:~/workspace/mcmc-chapter$ git fsck --full Checking object directories: 100% (256/256), done. error: HEAD: invalid sha1 pointer af9fc0c5939eee40f6be2ed66381d74ec2be895f error: refs/heads/master does not point to a valid object! error: refs/heads/master.u1conflict does not point to a valid object! error: 0e31469d372551bb2f51a186fa32795e39f94d5c: invalid sha1 pointer in cache-tree dangling blob 03511c9868b5dbac4ef1343956776ac508c7c2a2 missing blob 8b61d0135d3195966b443f6c73fb68466264c68e missing blob e89896b1282fbae6cf046bf21b62dd275aaa32f4 dangling blob dd09f7f1f033632b7ef90876d6802f5b5fede79a missing blob caab8e3d18f2b8c8947f79af7885cdeeeae192fd missing blob e4cf65ddf80338d50ecd4abcf1caf1de3127c229 </code></pre> <p>Step 5: Try <code>git reflog</code>. Fail because my HEAD is broken. </p> <pre><code>nathanvan@nathanvan-N61Jq:~/workspace/mcmc-chapter$ git reflog fatal: bad object HEAD </code></pre> <p>Step 6: Google. Find <a href="http://git.661346.n2.nabble.com/corrupted-Git-repository-td6498902.html" rel="noreferrer">this</a>. Manually get the last two lines of the reflog: </p> <pre><code>nathanvan@nathanvan-N61Jq:~/workspace/mcmc-chapter$ tail -n 2 .git/logs/refs/heads/master f2d4c4868ec7719317a8fce9dc18c4f2e00ede04 9f0abf890b113a287e10d56b66dbab66adc1662d Nathan VanHoudnos &lt;nathanvan@gmail.com&gt; 1347306977 -0400 commit: up to p. 24, including correcting spelling of my name 9f0abf890b113a287e10d56b66dbab66adc1662d af9fc0c5939eee40f6be2ed66381d74ec2be895f Nathan VanHoudnos &lt;nathanvan@gmail.com&gt; 1347358589 -0400 commit: fixed up to page 28 </code></pre> <p>Step 7: Note that from Step 6 we learned that the HEAD is currently pointing to the very last commit. So let's try to just look at the parent commit:</p> <pre><code>nathanvan@nathanvan-N61Jq:~/workspace/mcmc-chapter$ git show 9f0abf890b113a287e10d56b66dbab66adc1662d commit 9f0abf890b113a287e10d56b66dbab66adc1662d Author: Nathan VanHoudnos &lt;nathanvan@XXXXXX&gt; Date: Mon Sep 10 15:56:17 2012 -0400 up to p. 24, including correcting spelling of my name diff --git a/tex/MCMC-in-IRT.tex b/tex/MCMC-in-IRT.tex index 86e67a1..b860686 100644 --- a/tex/MCMC-in-IRT.tex +++ b/tex/MCMC-in-IRT.tex </code></pre> <p>It worked!</p> <p>Step 8: So now we need to point HEAD to 9f0abf890b113a287e10d56b66dbab66adc1662d. </p> <pre><code>nathanvan@nathanvan-N61Jq:~/workspace/mcmc-chapter$ git update-ref HEAD 9f0abf890b113a287e10d56b66dbab66adc1662d </code></pre> <p>Which didn't complain.</p> <p>Step 9: See what fsck says:</p> <pre><code>nathanvan@nathanvan-N61Jq:~/workspace/mcmc-chapter$ git fsck --full Checking object directories: 100% (256/256), done. error: refs/heads/master.u1conflict does not point to a valid object! error: 0e31469d372551bb2f51a186fa32795e39f94d5c: invalid sha1 pointer in cache-tree dangling blob 03511c9868b5dbac4ef1343956776ac508c7c2a2 missing blob 8b61d0135d3195966b443f6c73fb68466264c68e missing blob e89896b1282fbae6cf046bf21b62dd275aaa32f4 dangling blob dd09f7f1f033632b7ef90876d6802f5b5fede79a missing blob caab8e3d18f2b8c8947f79af7885cdeeeae192fd missing blob e4cf65ddf80338d50ecd4abcf1caf1de3127c229 </code></pre> <p>Step 10: The invalid sha1 pointer in cache-tree seemed like it was from a (now outdated) index file (<a href="http://www.spinics.net/lists/git/msg96103.html" rel="noreferrer">source</a>). So I killed it and reset the repo.</p> <pre><code>nathanvan@nathanvan-N61Jq:~/workspace/mcmc-chapter$ rm .git/index nathanvan@nathanvan-N61Jq:~/workspace/mcmc-chapter$ git reset Unstaged changes after reset: M tex/MCMC-in-IRT.tex M tex/recipe-example/build-example-plots.R M tex/recipe-example/build-failure-plots.R </code></pre> <p>Step 11: Looking at the fsck again...</p> <pre><code>nathanvan@nathanvan-N61Jq:~/workspace/mcmc-chapter$ git fsck --full Checking object directories: 100% (256/256), done. error: refs/heads/master.u1conflict does not point to a valid object! dangling blob 03511c9868b5dbac4ef1343956776ac508c7c2a2 dangling blob dd09f7f1f033632b7ef90876d6802f5b5fede79a </code></pre> <p>The <a href="https://stackoverflow.com/questions/9955713/git-dangling-blobs">dangling blobs are not errors</a>.

    1. COExcellent answer, together with all the steps and all. I suppose you saved me from googling each and every one of those!

    3. COHmm, my laptop died during a git operation (SparkleShare was trying to commit my notes as it died) and after that the repo was corrupted in this way. I followed your steps up till 6 but it seems like the last several commits were actually supposed to be part of the empty object files that I deleted? In fact the last 3 commits were basically completely broken so I guess there was nothing I could do. Luckily I don't actually need the individual commits from SparkleShare and I can just copy over the dirty file from one machine to another and merge.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
