Question

linux

Hello!
I'm trying to update packages on the server. I run yum update
I get:

Downloading packages:
Running transaction check
Running transaction test
Transaction test succeeded
Running transaction

sqlite3.ProgrammingError: You must not use 8-bit bytestrings unless you use a text_factory that can interpret 8-bit bytestrings (like text_factory = str). It is highly recommended that you instead just switch your application to Unicode strings.

Has anyone come across? How to fix? Thanks in advance.
PS What I tried, but it helped
yum-complete-transaction
yum history new
rm -rf /var/cache/yum
yum clean all
rm -f /var/lib/rpm/__db*

Answer 1

After they removed:
You should probably do:
rpm -vv –rebuilddb

Answer 2

This error is related to file system corruption. Specifically, there is corrupted information in the yum database.
rpm --rebuilddb won't help in this case.
You can find a corrupted database entry using the 'yumdb info' command
See an example here
