"tdnf check-udpdate" always required "tdnf clean all" to pickup updates

[dlinsley]

tdnf check-update does not appear to behave like yum check-update in how it refreshes the repo cache to determine if new packages are available. Cleaning the meta data is required every time in my experience with tdnf.

Example run:

dlinsley@photon-YRjrxkFmh [ ~ ]$ sudo tdnf check-update

...Expecting a list available package updates here but have nothing...

dlinsley@photon-YRjrxkFmh [ ~ ]$ sudo tdnf update
Nothing to do.
dlinsley@photon-YRjrxkFmh [ ~ ]$ sudo tdnf clean all

tdnf defaults metadata_expire to 48 hours. you can override (using metadata_expire settings per repo) or using --refresh with any command to refresh first, then run the command.

yum has a default expire time of 6 hours. however, dnf has set the default to 48 hours which is what tdnf follows.

Thanks @ppadmavilasom ! I still see this behavior when tdnf update weeks apart. I don't believe I would receive any updates unless a refresh is forced.

@dlinsley tdnf keeps a file called "lastrefresh" for each repo in /var/cache/tdnf/ and uses the file datetime on this file to trigger a refresh. could you check if you have the marker file in the above cache directory

[dlinsley]

Looks like this is working as designed. Noticed my lastrefresh file for a repo had an datetime of 7 days old. ran tdnf check-update and the refresh occured. lastrefresh datetime was updated .
