I have cross-posted this on ask.fedora.org as I am still uncertain whether this or the other side has the larger Fedora userbase.



For a few days now I could not install updates due to this error:

I found that one shall do these commands in order to fix it, and I tried, but it has not resolved the problem.



  • dnf clean all

  • dnf makecache

  • rpm --buildddb

On Ask Fedora somebody suggested that dnf is not able to recover from that and that one has to repair the SQLite database manually.



I have tried to run the command given,



sqlite3 history-<date>.sqlite ".dump" | sqlite3 history-<new date>.db && rm history-<date>.sqlite


Doing it on /var/lib/dnf/history/history-2015-10-25.sqlite had no effect. Doing it on /var/lib/dnf/history.sqlite resulted in a new error:

Looking further into the sqlite3 .dump thing, I see this:



/var/lib/dnf# sqlite3 history.sqlite .dump 
PRAGMA foreign_keys=OFF;
BEGIN TRANSACTION;
/**** ERROR: (10) disk I/O error *****/
ROLLBACK; -- due to errors


However, when I copy this history.sqlite into /tmp and execute that .dump there, I get a sensibly looking database. Also opening it with the GUI sqliteman works fine. It seems that the database itself is okay.



Dumping the database into a new file somewhere else and copying it back then gives me this:

How is this on Fedora 29, can I recover from this?

  • dnf clean all

  • dnf makecache

  • rpm --buildddb

On Ask Fedora somebody suggested that dnf is not able to recover from that and that one has to repair the SQLite database manually.



I have tried to run the command given,



sqlite3 history-<date>.sqlite ".dump" | sqlite3 history-<new date>.db && rm history-<date>.sqlite


Doing it on /var/lib/dnf/history/history-2015-10-25.sqlite had no effect. Doing it on /var/lib/dnf/history.sqlite resulted in a new error:

Looking further into the sqlite3 .dump thing, I see this:



/var/lib/dnf# sqlite3 history.sqlite .dump 
PRAGMA foreign_keys=OFF;
BEGIN TRANSACTION;
/**** ERROR: (10) disk I/O error *****/
ROLLBACK; -- due to errors


However, when I copy this history.sqlite into /tmp and execute that .dump there, I get a sensibly looking database. Also opening it with the GUI sqliteman works fine. It seems that the database itself is okay.



Dumping the database into a new file somewhere else and copying it back then gives me this:
