[SOLVED] After online upgrade to v. 9, unable to update

frankbell · 12-06-2023, 10:42 PM

I have a strange problem with Mageia after doing an online upgrade from v. 8. to v. 9.

When I try to run an update, I get the follwoing error:

Code:

# urpmi --auto-update
mirror list not found
Could not find a mirror from mirrorlist $MIRRORLIST

I searched for the error message and turne up several Mageia sites, but I could not find much helpful there. These are the sites:

https://wiki.mageia.org/en/Finding_Mageia_rsync_servers

https://mirrors.mageia.org/

https://wiki.mageia.org/en/Mageia_9_Errata

I did follow one of the suggestions. I opened drakconf, went to Software Management-->Configure media sources for install and update-->File-->Add a custom medium and added a repo from the repo list above. It did not work.

Before I do a reinstall, I thought should ask whether anyone has a suggestion as to how I could fix this without a reinstall.

I will add that when I did an online upgrade from v. 7 to v. 8, it went flawlessly.

If a transaction proceeds to remove /etc/resolv.conf, not found errors become expected behavior. I've done multiple Mageia updates in the past two days, and exactly this happened in one of them.

If it is a resolution problem, you can temporarily fix it by creating a resolv.conf file and putting into it the line

Code:

nameserver local_ip_address_of_your_router

.

In a way, I did that in advance. /etc/resolv.conf here is replicated as /etc/resolv.conf.latest, so I need only copy the copy back over the broken one, or into the void left by whatever removal transaction.

Thank you all for your responses. I'm been late getting back to this thread because, frankly, my brain is tired.

The odd thing is that websites seem to resolve properly.

I looked at my resolve.conf and found this. It points to a site belonging to my ISP.

Code:

# cat resolv.conf 
# Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8)
#     DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN
nameserver 68.105.28.11
nameserver 68.105.29.11
nameserver 68.105.28.12

I did a web search for "edit reolve.conf mageia" and the results made my brain even more tired.

Can someone point me to nice, concise, clear tutorial on how to make the edit?

Just seeking clarity, by "remove" do you mean "delete"?

Again, thank you.

They pretty much mean the same thing. However, one can cause the same intended effect with a mv (aka renaming) of resolv.conf to something like resolv.con, which deletes (aka removes) resolv.conf from the directory, replacing it with resolv.con. The file remains, but its original name does not, resulting in broken DNS, as if the file had been physically "deleted" (which we know isn't what delete {rm} actually does either).

Thanks. I just wanted to make sure I understood you correctly. I oft for asking a stupid question over making a stupid mistake any day of the week and twice on Sundays.

I'll try some things tomorrow and let you all know what happens.

(Like I said, everything's working fine except the updates, so I am not in panic mode, at least not yet.)

frankbell · 12-29-2023, 08:57 PM

Sorry for the delay, but it's the holidays and I've been distracted.

I deleted/remove resolv.conf, rebooted and got a new resolv.conf, just like the old resolv.conf.

I still get the same error when I try to run an update.

Code:

# urpmi --auto-update
mirror list not found
Could not find a mirror from mirrorlist $MIRRORLIST

I have also fired up drakconf and get a similar error when I try to updates:

Code:

Unable to update medium; it will be automatically disabled.

Errors:
mirror list not found
Could not find a mirror from mirrorlist $MIRRORLIST

Any additional suggestions as to where I might look would be greatly appreciated.

And, if you don't have any suggestions, thanks for trying.

I know nothing about Red Hat package management but from the error message, it looks to me as if urpmi is a shell script, not a binary. In which case, you ought to be able to find out what $MIRRORLIST is set to and how it relates to the mirrors list file that you actually have.

Are you able to ping your router? As prequel to trying to do a follow-up here, I did a fresh Mageia 9 installation, with my NIC statically configured. ip a and ip route produced expected output, and I have a valid /etc/resolv.conf (same one used on the other 15 distros on that PC), but I couldn't do anything with it. Ping 127.0.0.1 worked, but none other. e.g. ping 192.168.<self> or router produced "ping: sendmsg: Operation not permitted", something I had never seen before. Then it dawned on me this was a default installation, something I hadn't done since early Mandrake days, and thus firewall must have been installed and enabled. Turning it off got everything network working. Did your upgrade add or change your firewall behavior?

Just to wrap things up, I finally got around to doing a fresh install of Mageia v. 9. It went very smoothly.

Since I have a separate /home partition, the great majority of my existing configuration was retained. Firefox and Thunderbird, for example, worked just fine out of the box, with all configuration and plugins still functional.

I did have to install xscreensaver anew and no doubt I shall run across some other speed bumps along the way, but, generally, everything's okay and I can update and add software just fine.
