curl Error

I am using openSUSE Leap 15.3, 64-bit and KDE environment.

When I execute the zypper up command to update my OS I get the following error message for Firefox and Thunderbird files:

This is not the first time that I get such error messages. How do I fix the issue?

I get those from time to time, though it is usually with Tumbleweed updates.

Hmm, I recently got some when updating Leap 15.4 Alpha.

In your case, this appears to be an SSL error. You might try using the plain “http” (instead of “https”) access for the repos. There’s no real benefit to using “https” there, except for privacy (snoopers knowing what you download). The packages are protected with GPG signatures.

I usually just retry.

After several years of hassle free download from http://download.opensuse.org/ duping Tumbleweed failed with annoying curl errors in the last week. Retrying succeeded in each case.
