Permission denied when updating CentOS 8 Streams
by Mathieu Baudier 22 Feb '21

22 Feb '21

Hello, On a remote server (in an IPv6-only infrastructure) I am getting the following error when trying to update CentOS 8 Streams x86_64: $ sudo dnf upgrade --refresh Failed to set locale, defaulting to C.UTF-8 CentOS Stream 8 - AppStream 0.0 B/s | 0 B 00:16 Errors during downloading metadata for repository 'appstream': - Curl error (7): Couldn't connect to server for http://mirrorlist.centos.org/?release=8-stream&arch=x86_64&repo=AppStream&i… [Failed to connect to mirrorlist.centos.org port 80: Permission denied] Error: Failed to download metadata for repo 'appstream': Cannot prepare internal mirrorlist: Curl error (7): Couldn't connect to server for http://mirrorlist.centos.org/?release=8-stream&arch=x86_64&repo=AppStream&i… [Failed to connect to mirrorlist.centos.org port 80: Permission denied] Trying to retrieve the mirror list with wget gives similar errors (see log below). This is a development VM and I was playing with firewalld zones on this interface (drop, block, etc.) in order to see the most restrictive that I could use in order to update a system. But the error also appears if I switch back the zone to public. Could it be that my address has been blacklisted because of all these tests? >From my laptop, also running CentOS 8 Streams, everything is working as expected. Thank in advance for hints on how to analyze further!

Date question
by Jerry Geis 18 Feb '21

18 Feb '21

SO from the man page on date I can do current=`TZ=":America/Indianapolis" date` echo $current current=`TZ=":America/Los_Angeles" date ` echo $current And I get correct data. LA is 3 hours earlier. But doing this: current=`TZ=":America/Indianapolis" date +%s` echo $current current=`TZ=":America/Los_Angeles" date +%s` echo $current I get the same data - its not 3 hours different. What am I not doing correct ? Thanks, Jerry

Using C7 as host to C5 guest
by Jerry Geis 17 Feb '21

17 Feb '21

Hi all, I am using C7 as a host to a C5 image. This used to boot. I tried today to boot up the C5 image and it get stuck now on the boot screen. Any thoughts on why ? It stuck on the screen that shows root (hd0,0) Filesystem type ext2fs partition type 0x83 kernel /boot/vmlinuz-2.16.18-402.el5 Then nothing... I know C5 is way out of date - but have a couple places still using it. Thoughts on getting this to boot up ? Jerry

The search term you're looking for is "NIC bonding". Here's the first hit I get from Google: <https://www.enterprisenetworkingplanet.com/linux_unix/article.php/3850636/U…>

Hi devel I've noticed a while ago that Redhat's Bugzilla has had, in "Red Hat Enterprise Linux 8" as one of the options "CentOS Stream" - which is where I've been recently reporting to. But I wonder about bugs relating to CentOS infra/repos - where to submit those, would you know? many thanks, L.

Delta Chat on CentOS 7
by H 14 Feb '21

14 Feb '21

Has anyone compiled Delta Chat to run on CentOS 7? I know it is available as a Flatpak and as an AppImage (https://delta.chat/en/download) but I wonder if there might be benefits to compile and run natively on CentOS.
