When I open Ubuntu Software Manager on my machine, sometimes it returns this error:
Any idea about it?
I tried to delete the cache:
DNSSEC supported by current servers: no
Transactions
Current Transactions: 0
Total Transactions: 93545
Cache
Current Cache Size: 4
Cache Hits: 3598
Cache Misses: 17357
DNSSEC Verdicts
Secure: 0
Insecure: 0
Bogus: 0
Indeterminate: 0
and tried to change the server, trying different servers from US, Fr, Ch, Italy, and also trying the select better service
option.
At my eyes, it looks like any server I choose, the IP address remains the same: 151.101.38.49
$ ping p2.shared.global.fastly.net
PING p2.shared.global.fastly.net (151.101.38.49) 56(84) bytes of data.
64 bytes from 151.101.38.49 (151.101.38.49): icmp_seq=1 ttl=56 time=31.7 ms
nslookup cdn.fwupd.org
to see if pinging the histname causes the DNS servers to pick up the address for the site, and then opening updates./etc/apt/sources.list
? It's just a hunch, but I've seen a similar message when I accidentally made a nonsense edit to that file.$ nslookup cdn.fwupd.org
Server: 127.0.0.53 Address: 127.0.0.53#53 Non-authoritative answer: cdn.fwupd.org canonical name = p2.shared.global.fastly.net. Name: p2.shared.global.fastly.net Address: 151.101.38.49
